Training for marathon swims: Pool vs. open water

Newbie marathon swimmers often wonder how they should allocate their training time between the pool and open water. There’s no simple answer: It depends on a variety of factors unique to the individual. A few questions to ask yourself:

What’s the target swim? Distance, water temp, conditions, etc. The further outside neutral conditions your target swim is, the more open water you’ll want to incorporate into your training. (To train for cold water… swim in cold water.)

Are you training to finish (regardless of time), or are you training to race? The more speed matters in your target swim, the more high-quality interval training in the pool you’ll probably want to do.

What’s most convenient? If you live next to a safe body of open water, but far away from the nearest pool, this may tip the balance towards OWS. In my experience, convenience promotes consistency — and consistency promotes results.

What do you inherently enjoy? If you have access to a high-quality Masters pool squad with good coaching and fun lanemates, this may tip the balance towards the pool. If you get blissed out by open water, this may tip the balance towards OWS. Enjoyment promotes consistency, and consistency promotes results.

Consistency is the main thing, and I’d say whatever formula helps you swim consistently is fine.

For the sake of argument, though, let’s say convenience and enjoyment don’t pose obstacles for you. All else being equal, what’s the ideal combination of pool & open water training?

My personal beliefs are, you can’t beat the pool for improving speed and stroke technique; and you can’t beat open water for acclimating to cold water and rough conditions.

Perhaps that’s just common sense. But there are some less-obvious corollaries:

In my opinion, for many mainstream marathon swims it’s perfectly OK to do most of your training in the pool. When I did the 24-mile Tampa Bay Marathon Swim in April 2011, I hadn’t been in open water since the previous October.  I won by 42 minutes.

I don’t mean to say open-water training isn’t valuable or important; but I do think sometimes marathon swimmers underestimate the value of pool training.

In that vein, I was struck by this recent tweet from Swim Smooth founder and 2013 MIMS champion Paul Newsome:

Like me, Paul comes from a pool-swimming background, but as an adult competes primarily in long-distance open water swims. Like me, he does most of his training in the pool, even for moderately “cold” swims such as MIMS 2013 (61F).

Among elite professional open water swimmers, the ratio of pool to open-water training approaches 100%. In the case of my old friend Mark, who competed in the Beijing Olympic 10K, his pool training didn’t “approach” 100% – it was 100%. Aside from organized races, he did literally zero open water training in preparation for the Olympics.

What are the exceptions to this rule? You probably already know the answer: very long, very cold swims. You must acclimate. The colder and longer the swim, the more longcold water training you should be doing. For me, anything below about 18C (64.4F) for marathon distance, and I’d aim to be doing at least some of my training outside the warm pool, in cold water. At 15C for the target swim, I’d spend proportionally more time in open water. At 12C, even more. Body fat will also be a factor here.

But still, even for long, cold swims — I probably wouldn’t let my ratio of pool-to-OW training go below 50%. The pool is just so, so much better for developing (and maintaining) speed and fitness. The extra speed (resulting in faster times) and extra fitness (resulting in the ability to maintain higher energy output for longer), more than make up for the opportunity costs in cold-water acclimation.

Taking liberty with a well-known proverb:

All OWS and no pool makes Jack a slow swimmer-boy.

Nyad Agonistes: The anatomy of a social media campaign

My collaborator and friend Donal Buckley has been writing an eloquent, impassioned, and probably definitive account of l’Affaire Nyad (Part 1, Part 2, Part 3, Part 4, Part 5). I will collect my thoughts on The Controversy at some point, but in the meantime please consider Donal’s voice as my own.

What follows is my attempt at a real-time narrative of The Controversy, from the start of the swim the morning of August 31 through the evening of September 8, when a New York Times article by Suzanne Sataline finally forced Diana Nyad and her team to speak to the skepticism among her fellow marathon swimmers about the details of her achievement.

I assemble developments from a variety of sources – the Marathon Swimmers Forum, Facebook, national media outlets, and my personal contacts during this time – into a coherent narrative of a remarkable social media campaign.

August 31, 2013. 8:59am, Eastern Daylight Time (all subsequent times also in EDT). According to reports from her crew, Diana Nyad enters the water just west of Havana, Cuba, and begins swimming.

September 1, 8:00pm. Diana Nyad is filmed swimming at Hour 33, at which point, according to her GPS data, she was progressing toward her destination at more than 5 miles per hour (44.7 seconds per 100m).

[YouTube video link]

September 1, 11:00pm. 38 hours into the swim, as reported by Diana’s crew, “winds suddenly rose to 23 knots” and the team “went into squall protocol.”

September 1, 11:38pm. American TV news network CNN, which has financially supported other Nyad swim attempts, reports that Diana “has broken swimmer Penny Palfrey’s 2012 distance record in the Cuba to Florida swim.”

September 2, 1:27am. “Flotilla back in formation” and “free of the storm,” according to crew reports. During the storm, Diana is still progressing at more than 4mph according to her GPS data.

Experienced marathon swimmers who actually know what swimming in 23-knot winds (Beaufort Force VI) is like are… curious.

September 2, 7:15am. Diana’s crew reports: “…the handlers were not stopping her to eat and drink overnight in the hopes that swimming would keep her warm.” 7:30am. Diana’s crew reports: “…the whistle blew for Diana’s first feeding stop since before midnight.”

Experienced marathon swimmers wonder: “No food or drink since midnight? Seven and a half hours without calories or liquids?”

September 2, 12:33pm. As Diana nears Key West, the skeptical comments begin. Triple Crown channel swimmer and 8 Bridges co-founder David Barra writes on Facebook:

….pretty sure the Gulf Stream doesn’t work like that. #smokeandmirrors

The comments on Barra’s Facebook thread anticipate two important directions of the subsequent controversy:

  1. The strong west-to-east Gulf Stream currents – as shown on both predictive models and live data – casting doubt on Diana’s strong south-to-north progress across the Strait. Tampa Bay Marathon Swim race director Ron Collins’ comments are especially helpful.
  2. The lack of qualified, independent observers on Diana’s swim. Triple Crown channel swimmer and professional FINA Grand Prix swimmer Mallory Mead says:

Ultimately the thing I really can’t get over, is why she didn’t have a truly independent observer. Like someone the open water swimming community knows and respects. Diana knows the community doesn’t trust her (and that is nothing new!) so if she cared, she would have made sure to have someone on the boat to verify.

But at the very least she doesn’t give a rats ass about the open water swimming community, because she KNOWS it doesn’t matter what we think, the media will print anything she says as truth.

September 2, 1:26pm. Marathon Swimmers Forum member “bruck” posts a prophetic comment:

IF Diana Nyad swam from Cuba to Florida unassisted, with the jelly costume and face mask being the only deviation from traditional channel rules, then it should be celebrated as one of the world’s greatest endurance feats.

I don’t think a little skepticism about the current swim is unfair or mean, given the dubious circumstances and reporting of her previous swims.

Assuming she finishes, I hope she and her team will make completely clear what, exactly, has been accomplished. Did she swim the whole way? Did she ever rest on the boat? Was she ever towed by the boat? How does she account for the unusually fast progress she made, seemingly far in excess of her personal swim speed?

Then the marathon swimming community can evaluate the claims and the evidence, and decide whether we believe her.

September 2, 1:53pm. Diana Nyad swims ashore in Key West, 53 hours after departing Havana. To experienced marathon swimmers who have undertaken 24-hour swims, much less 53-hour swims, she appears surprisingly sprightly for anyone of any age after such an effort. Penny Palfrey, a younger and much stronger swimmer, was confined to a hospital for a day after her 80-mile, 41-hour attempt last year.

On the beach, Diana amazingly has the presence and clarity of mind to deliver an inspirational sound byte for the cameras:

I have three messages: One is we should never ever give up. Two is you are never too old to chase your dreams. And three is it looks like a solitary sport but it takes a team.

[YouTube video link]

September 2, evening. The story of Diana’s swim is global news. Media outlets (e.g., New York Times, CNN) report that Diana swam 53 hours nonstop between Havana and Key West. These reports, evidently, were based purely on the word of Diana and her team, without fact-checking.

On the Marathon Swimmers Forum, the discussion has already zeroed in on the two most suspicious interesting aspects of the swim:

  1. Diana’s strong south-to-north progress across strong west-to-east currents (according to the live publicly-available oceanography data).
  2. The 7.5-hour stretch on the second night of the swim, during which Diana’s crew reported she went without feeding or drinking.

September 3, 9:04am. In an admittedly purposeful effort to stir up more critical analysis of Diana’s swim, I ask on Facebook:

Did any of the journalists covering Diana Nyad ask her directly if she swam the whole way, under her own power? Just askin’.

It becomes the most engaged post in the history of my personal Facebook account. Most are supportive. Catalina solo record-holder Grace van der Byl says:

Thanks for asking what many have been thinking….

Irish channel swimmer Colm Breathnach cites the famous Sagan aphorism:

Extraordinary claims require extraordinary evidence.

Others seem to take it quite personally. Chicago channel swimmer Nial Funchion declares:

Who gives a fuck about ‘your sport’ your ‘time’, ‘rules’, there is integrity in putting the soul out there for the viewing. When that is done consider it a gift There will always be critics, they suck And hide and throw daggers through the hearts of great spirits. Man she gave us he world as human beings should live it. I’ve been doing marathon swimming w/o the bs rules for 22 years w integrity…reaching, building, mending. I don’t need rules for that.

My brother Garrett responds to Nial:

I have a hard time understanding why a human being would willingly shield himself from attainable knowledge about that which he “believes.” Isn’t curiosity a natural impulse of the reasoning mind? And why not believe in things that have been, to the best of our rational ability, verified? It takes ten minutes to read the Nyad discussion in the forum and to enlarge one’s knowledge about her feat. The idea that Nyad’s biggest fans would knowingly avoid such an experience blows my mind.

See the full, fascinating, and impassioned thread HERE.

September 3, 1:02pm. Over on the Marathon Swimmers Forum, discussion had been building to a crescendo throughout the swim, in two separate threads: Diana Nyad’s epic swim (primarily cheerleading-type comments) and Here we go again… (primarily critical comments). Once the swim ended, I merged a few comments from each into a new thread focusing on the post-swim analysis: 110 miles, 53 hours: Questions for Diana Nyad. This thread would soon become the most read, most commented thread in Forum history, and the subject of national news.

Evening of Sept 4 – Morning of Sept 5. The Forum discussion begins to focus on the technical details of Diana’s speed across the Strait. How did she seemingly swim faster across a strong cross-current than Trent Grimsey swam across the English Channel? Andrew Malinak does some Google Earth trigonometry, and I attempt to derive “speed segments” from the postings on her blog.

September 4, 7pm. Suzanne Sataline, a freelance journalist and CIBBOWS swimmer, leaves me a voicemail. I return her call later that evening. She interviews me for a story she is writing about the marathon swimming community’s skepticism of Diana Nyad’s swim. The story is slated to appear on National Geographic Online.

September 4, 8:10pm. As the controversy on the Forum grows, Steven Munatones CC’s me on an email to Forrest Nelson, asking if he would like to “review the data and documentation that Diana’s team gave to me.” Steve does not specify the nature of the data that Team Nyad has provided to him, but I reply that I would certainly be interested in reviewing it.

Now almost five weeks later, it is still not clear what came of this offer.

September 5, early AM. On the Forum, the curious story of Walter Poenisch is mentioned for the first time.

We also hear, for the first time, from a member of Diana’s Xtreme Dream Team. Her kayak team captain, Don “Woodkayaker” McCumber, says he was on the water with Diana for “approximately 1/3 of the swim,” and claims “she did NOT do ANYTHING to compromise her record.” McCumber notes that Diana was “observed around the clock by two independent observers from the Open Water Swimming Association – Roger McVeigh, and Janet Hinkle.”

For the record, there is no such organization as the “Open Water Swimming Association.”

Forum members are excited to hear from someone who actually witnessed the swim in person, and post several reasonable questions for Mr. McCumber.

Soon thereafter, Xtreme Dream Kayak Team Captain Don “Woodkayaker” McCumber loses his temper and leaves the Forum in a righteous fury:

Why must so many people in this group want to pick apart every little thing? Take a look at yourselves… you are an embarrassment. Accept the FACT that she did this swim. Get a LIFE.

Xtreme Dream Kayak Team Captain Don “Woodkayaker” McCumber also makes the unintentionally revealing suggestion: “Maybe your stodgy little rule book needs to be edited.”

September 5, mid-morning. Suzanne Sataline’s piece for National Geographic, the first mention of the controversy in the national media, is published online.

Swimmers Question Diana Nyad’s Cuba-to-Florida Feat: Some demand more details about the record-setting open-water marathon swim (NationalGeographic.com)

September 5, 6:12pm. Marathon swimming legend Penny Palfrey, whose 2012 attempt was the closest to swimming the Florida Straits unassisted, and whose open-ocean distance record Diana Nyad is claiming to have bested, comments to the Forum:

If an athlete claims to have broken the record of another athlete, surely both events should have been conducted under the same set of rules.

Penny, who used a stinger suit on her 2012 swim, also pointedly mentions she put on and took off the stinger suit by herself, without help from crew.

September 6, mid-morning. Forum member and engineer Andrew Malinak posts the data-analysis-heard-’round-the-world.

September 6, 2:45pm. Outside Magazine, which promoted Diana Nyad as one of their 2013 “Adventurers of the Year,” re-reports Sataline’s National Geographic piece:

Nyad’s Cuba-Florida Swim Under Attack: Team has yet to release data (OutsideOnline.com)

September 6, 3pm. Diana Nyad makes her first public comment about the controversy, on my personal Facebook page. Her claim that she “never of course touched a boat or another person” is notable, given her later admission that actually she did touch other people during the swim, quite frequently.


Forum member and channel swimmer Owen O’Keefe later notes:

She (or whoever was writing on her behalf) is a true master of ambiguity. I’m not an expert on English grammar, but I’m pretty sure that the statement “Those will be judged by the auspices of the sport and different record keepers” does not make one ounce of sense.

September 6, mid-afternoon. Marathonswimmers.org is nearly inaccessible due to slow server response time. I assume we have reached bandwidth limits due to increased visitor traffic, but after consulting with my hosting company’s tech support, it becomes clear that we’ve been the victim of a denial-of-service (DOS) attack. I work with the hosting company to implement enhanced security measures to protect against future attacks.

September 6, 4:42pm. Snarky sports-news website Deadspin picks up the story.

Was Diana Nyad’s Cuba-To-Florida Swim Legit? Haters Want To Know. (Deadspin.com)

Deadspin, which originally broke the Manti T’eo dead-girlfriend-hoax story, is widely read and often foreshadows breaking national news.

September 6, 5:30pm. I speak again with Suzanne Sataline, who is now working on a follow-up story for the New York Times.

September 6, late evening.  I re-format Andrew’s chart with more readily interpretable axes (km per hour instead of km per 6.75 minutes; elapsed hours instead of number of 6.75-minute intervals):

September 7, 6:49pm. Chris Moschini, the man behind the DianaNyad.com website, posts the data from Diana’s SPOT GPS trackers, including (importantly) the timestamps associated with each set of coordinates.

September 8, 2:34pm. As the New York Times nears publication of Suzanne Sataline’s story, the Associated Press goes live with a story quoting Andrew Malinak and an oceanographer named Mitch Roffer, who says it’s possible Nyad caught a rare south-to-north eddy of the Gulf Stream that would explain her quick progress.

Nyad’s Team Responds to Skeptics Doubting Her Swim (bigstory.ap.org)

September 8, 5:58pm. Forum member John Royer re-does Andrew Malinak’s analysis using the timestamped data provided by Chris Moschini. “The main features of the plot are pretty much identical.”

September 8, 8:34pm. Professional journalist and open water swimmer “rosemarymint” posts a comment to the Forum that elegantly summarizes the dilemmas confronting any journalist covering this emerging story:

I was not following the excruciating detail of the swim as it was happening online, nor do I have a TV (or cable.) I do know that CNN had a huge amount of involvement in the swim, even offering their satellite link for the data to the website (per the post by Diana’s web team.) Did CNN have a reporter (staff or freelancer) on any of the boats with the flotilla? This could become a credibility issue for them if they did.

Second: does anyone know any Florida Strait current experts that were NOT involved with the swim? We have now seen the brief visual analysis of the GPS/timestamp info, but there still is a big missing piece. Is there proof from an independent scientific source (and is not commercial in nature) that the currents could have moved the way Diana’s camp says they did and could explain the swim speeds? And could they have moved that way during those exact moments?

Have to admit, I’m more than a little surprised by the pervasive lack of skepticism among the media. Yes, we all love a good heart-warming story where a human being achieves something absolutely extraordinary, but the initial data do not pass the smell test. I can’t have any conclusions yet because there still are not enough data points to fully answer questions, but my flags are more than waving in the air. The fact that Diana’s swimming peers have such intense skepticism should be enough for a lot of people, but apparently not.

September 8, 10:00pm. Suzanne Sataline’s article for the New York Times goes live.

Celebration Gives Way to Questions and Doubt After a Record Swim (nytimes.com)

September 8, 11:57pm. I and several others receive an email from Steven Munatones, inviting us to hear from Diana Nyad and her team on a Skype conference call scheduled for the evening of September 10.

Non-Swim Report: Tomales Bay White Shark Swimming Association Fall “Chomp”

2013-10-05 16_07_39-www.parks.ca.gov_pages_470_files_TomalesBaySPWebLayout2013.pdfEach fall and spring, the channel swimmer / bubble-cap aficionado / legendary South Ender known as El Sharko (occasionally “Sir Sharko,” sometimes shortened to “Sharko,” and just “Chris” to his wife) organizes a swim & BBQ at Heart’s Desire Beach in Tomales Bay State Park, north of San Francisco.

In homage to the white sharks who breed near the mouth of Tomales Bay, this event is known as the “Tomales Bay White Shark Swimming Association (TBWSSA) Chomp” (alternatively, “Tomales Bay Dangerous ‘Swim with the White Sharks’ Chomp,” often shortened to simply “The Chomp”). Sharko’s sanguine approach to the oft-repressed fact of VW-sized predators in our local waters is encapsulated by his calling card: “I never met a shark I didn’t like.”

The “Fall Chomp” of 2013 fell on what must surely go down as one of the most glorious days of the year: 80 degrees, windless clear skies all the way to the Farallons. Heart’s Desire Beach, about two-thirds of the way inland (8.5 miles) from the Bay mouth, lived up to its name.

I’m coming off a head cold, so I opted for a patch of shade and a book instead of the admittedly inviting Bay waters. Shallow Tomales Bay usually runs a few degrees warmer than San Francisco Bay, and was mid-60s F according to reports.

The swim portion of the Chomp was low-key and non-competitive. They swam north (into the flood) along the western shore for about a mile, and then back, escorted by a few kayaks.

Post-swim, an alternative meaning of the “Chomp” became clear. Hungry swimmers feasted on clam chowder, BBQ’d Tomales Bay oysters, and sundry potluck items.

The Chomp concluded with… wait for it… a poetry reading. A comedic recitation of primarily swimming-, ocean-, or South End-related verse aptly called the “Wet Poets’ Society.”

Some read canonical poems (e.g., Whitman’s “World Below the Brine“), others read original creations (one favorite, an ode to the South End men’s sauna). Cathy sang her own Sharko Song, a cappella to the tune of “Rawhide.”

We made it back to the city by early afternoon, and the day ended even more spectacularly than it began. The sun set directly over the Farallon Islands, clearly visible 30 miles offshore, casting the unusually glassy Pacific in a startling glow.

AP: Nyad’s team responds to skeptics doubting her swim

The Associated Press published a well-reported article on the marathon swimming community’s skepticism of Diana Nyad’s swim from Cuba to Florida. I am re-posting it here, with my comments in blue.

Nyad’s team responds to skeptics doubting her swim

By Jennifer Kay – September 8, 2013. 1:13 PM EDT

MIAMI (AP) — Diana Nyad’s 110-mile swim from Cuba to Florida has generated positive publicity and adoration for the 64-year-old endurance athlete — along with skepticism from some members of the small community of marathon swimmers who are questioning whether she accomplished the feat honestly.

>> Or rather, swimmers who just want more information, to understand how such an incredible swim was accomplished – a swim that even noted open-water swimming commentator Steven Munatones has said is impossible.

On social media and the online Marathon Swimmers Forum, long-distance swimmers have been debating whether Nyad got a boost from the boat that was accompanying her — either by getting in it or holding onto it — during a particularly speedy stretch of her swim. They also question whether she violated the traditions of her sport — many follow strict guidelines known as the English Channel rules — by using a specialized mask and wetsuit to protect herself from jellyfish.

>> I assume “wetsuit” is a misunderstanding by the reporter, rather than something Diana’s team actually admitted to. Diana has acknowledged wearing a non-neoprene (non-buoyant) bodysuit to protect against jellyfish stings.

“When you know how hard it is, you kind of want those details,” said Andrew Malinak, a Seattle long-distance swimmer who crunched the data available from the GPS positions tracked on Nyad’s website and concluded that he didn’t trust what he saw.

Nyad’s navigator and one of the swim’s official observers told The Associated Press this weekend that Nyad didn’t cheat and that she was aided during the rapid part of her swim by a swift current. And neither Nyad nor her team ever said she would follow English Channel rules, developed for swimming the waters between England and France. Those rules outlaw neoprene wetsuits and contact with a support boat. Nyad wore a full non-neoprene bodysuit, gloves, booties and a silicone mask at night, when jellyfish are a particular problem, and removed the suit once she got over the reef on her approach to Key West.

>> The marathon swimming community’s questions aren’t really about whether she followed English Channel rules – it was always obvious that she didn’t, and as AP says, she never claimed to follow them anyway. The more important issue is the degree of assistance she received – assistance such as touching or holding the boat or kayak, and being touched by her crew. This is important because, aside from the jellyfish suit and mask, she seems to be claiming an “unassisted” swim – which has a specific meaning to marathon swimmers.

According to Nyad’s team, she finished the swim Monday afternoon after roughly 53 hours in the water, becoming the first to do so without a shark cage. It was her fifth try, an endeavor apparently free from the boat troubles, bad weather, illnesses and jellyfish encounters that have bedeviled Nyad and other swimmers in recent years.

Nyad’s progress was tracked online via GPS by her team, and some critics say they think information is missing.

Many wonder about a roughly seven-hour stretch when Nyad apparently didn’t stop to eat or drink, recalling her 2012 attempt when she got onto the boat for hours during rough weather. Nyad eventually got back into the water to try finishing, but her team was criticized for delaying the release of that information to the public.

Malinak said the hours-long spike in Nyad’s speed after 27 hours of swimming is particularly questionable — she went from her normal pace of roughly 1.5 mph to more than 3 mph, then slowed down again as she approached Key West.

>> Moreover, as shown in this chart, Ms. Nyad briefly averaged 10 km per hour (6.2 mph) over a 40-minute period around Hour 30.

Nyad’s spokeswomen did not immediately return telephone calls this weekend, but her navigator and Janet Hinkle, one of the official observers for the swim, told the AP that Nyad didn’t cheat.

Navigator John Bartlett said the increased speed was due to the fast-moving Gulf Stream working in her favor, nothing more.

“At some points we were doing almost 4 miles an hour,” Bartlett said. “That’s just the way it works. If the current is in your favor at all, that explains it.”

The data collected by Bartlett and two observers will be submitted to three open-water swimming associations and the Guinness World Records for verification, Bartlett said.

>> Which open-water swimming associations? And what record(s) specifically will this swim be considered for in the Guinness Book?

An oceanographer not affiliated with Nyad’s team said the swimmer couldn’t have picked a more perfect current to get from Havana to Key West.

Mitch Roffer of Melbourne-based Roffer’s Ocean Fishing Forecasting Service Inc. said he got an email questioning whether Nyad’s swim was a hoax, so he decided to look at the charts for himself. What he saw convinced him that she could do it.

“Many times that current runs west-east and you’re constantly fighting the current if you’re swimming north. In this case, it was in the shape of an S, and the angle was almost exactly from Havana to Key West,” Roffer said.

>> This is good stuff. I’d love to hear more details about how oceanographers such as Mr. Roffer determine the direction & speed of the currents, and which charts he is using.

Janet Hinkle, a Key West boat captain and acquaintance of Nyad’s, was called to be an observer for the swim when Steve Munatones, a former U.S. national open-water coach, was unable to make it. “I can say unequivocally she swam every stroke without question,” Hinkle said.

>> By that statement, are we to assume Ms. Hinkle remained awake and watching Ms. Nyad for 53 hours continuously?

Critics have said Hinkle was too close to Nyad to be an independent observer of her swim. Hinkle has in the past helped Nyad by providing housing for her when the swimmer stayed in the Florida Keys, but she said she remained on the periphery of Nyad’s team. “I think anyone who knows me knows me as a person of high integrity. I believe that’s why Diana asked me, and I took my job very seriously,” Hinkle said. “She was giving her all and I would give her my best.”

>> It’s good to hear that Ms. Hinkle is a person of high integrity, but I think the marathon swimming community also wants to know: What (if anything) does she know about open water swimming? What is her previous experience observing swims?

Since none of the various open-water swimming associations dictate how someone should swim from Cuba to Florida — officially accomplished only by Nyad and Susie Maroney, who used a shark cage — Nyad just had to follow generally accepted rules about not getting out of the water or using equipment such as fins.

>> Not making intentional physical contact with other people (crew) or objects (boats, kayaks) is also a “generally accepted” rule of open water swimming – one of the oldest and most fundamental. Was Ms. Nyad following this rule? Photos showing her crew assisting her into her jellyfish suit would seem to indicate otherwise.

Australian Chloe McCardel followed English Channel rules in her attempt to swim the Florida Straits in June. She had to be pulled from the water after 11 hours after being stung jellyfish.

“Generally the rules are: You walk in, you swim across and you walk out, and you do it under your own power,” said Munatones, who consulted with Nyad for this swim and observed her attempts in 2011 and 2012.

The elaborate, full-body wet suit and protective mask Nyad wore to protect herself from venomous jellyfish actually weighed her down, Munatones said.

>> Again, I think the term “wetsuit” here is a misunderstanding by the reporter rather than something Munatones said.

“To put that on is like putting on a wedding gown in the ocean,” he said. “It’s different from the English Channel rules, but the water is different from the English Channel.”

To many, it seems Nyad hasn’t exactly endeared herself to those in the marathon swimming community. Some consider her primarily concerned with gaining the spotlight instead of helping others advance the sport.

At her post-swim news conference on Tuesday, Nyad admitted that she had not been rooting for McCardel and that she was miffed some members of her team would jump ship to work for a competitor.

McCardel said she was disappointed to hear Nyad call those crew members “traitors.”

>> Actually, this doesn’t bother me as much as it seems to bother others. It’s not classy or gracious, but it’s undeniably honest. To me, integrity and transparency are more paramount values in marathon swimming than being a likeable person. So kudos to Diana for her honesty in admitting this.

“One of the greatest things, I believe, about international marathon swimming is how people across the world support crew for and mentor each other. I wouldn’t change this aspect of our sport for the world!” McCardel posted on her Facebook page.

Diana Nyad Week

This past Monday, the most famous and charismatic open water swimmer of modern times, Diana Nyad, emerged from the sea at Key West and fulfilled her dream of swimming the Straits of Florida.

Ms. Nyad’s feat was headline news around the world – probably the biggest mainstream headlines for open water swimming of my lifetime. Millions were inspired by the dogged will of a 64-year old woman, taking on a challenge that had already defeated her four times, and had eluded swimmers half her age and twice her speed.

When she somehow had the presence of mind, still dripping wet, to urge the crowd gathered on the beach: “Never, ever give up… You are never too old to chase your dreams,” well… it was the stuff of movies. Incidentally, a documentary film about Ms. Nyad’s thirty-year quest – The Other Shore – will be released in three weeks.

By temperament, I’m not typically inspired by platitudes. But as a fellow marathon swimmer, I was inspired by the possibilities suggested by Diana’s swim. If it’s possible for a 64-year old to swim 110 miles in 53 hours, then anything is possible.

As a marathon swimmer, I’m also obsessed with details… data… information. Many of us are – I think it’s one reason the Marathon Swimmers Forum works so well. And in reading through Diana’s crew’s live-blog, trying to suss out how this incredible swim happened, I was struck by how little information there actually was. There was a lot of content, but most of it seemed aimed at the casual follower (or even pre-written), with little of the hard data that experienced marathon swimmers seek in piecing together a story of a swim.

Among other reasons, these details matter because Ms. Nyad is claiming – and the media reporting without fact-checking – a new world record for longest-distance nonstop, unassisted ocean swim, previously set by Penny Palfrey. Actually, forget the long-distance record: If Ms. Nyad’s swim was indeed nonstop and unassisted, as claimed, it might be the greatest marathon swim of all time, by any person, of any age.

And so it began. At first, just a discussion; but eventually, a full-fledged social media campaign among the global community of marathon swimmers – at Marathonswimmers.org and on Facebook – to encourage Ms. Nyad and her team to publicly release her swim data. And, in its own way, just as unprecedented as the swim itself.

As a freelance writer and open-water swimmer, Suzanne Sataline was in a perfect position to pick up on this emerging story. Thursday morning, her article went live at National Geographic Online:

The National Geographic piece was soon re-reported by other outlets:

EDIT: A few hours after this post went live, the Associated Press published a well-reported story including statements from Diana’s team:

The story was syndicated by the San Francisco ChronicleUSA Today, and The Guardian.

The result has been unprecedented traffic to Marathonswimmers.org, and even a DoS attack, which frankly I take as a compliment. It’s been an interesting week in the world of marathon swimming – and at my keyboard.

Stay tuned — the story continues to develop…

Swim Report: Kirby Cove to Aquatic Park

Two days before Bay to Breakers in May (yes, it’s a belated report), an oversubscribed volunteer corps opened up a couple spots on another SERC club swim: Kirby Cove to Aquatic Park. Kirby Cove is the same beach on the Marin Headlands where Cathy finished her “Three Bridges” swim in March. Outside the Golden Gate, but not as far as Point Diablo or Point Bonita. At 4.2 miles (current-assisted), it’s one of the longer SERC club swims, so a bit odd to have on the same weekend as Bay to Breakers.

I wasn’t planning to swim that morning and showed up to help kayak or time. It turned out there were plenty of volunteers, so I figured what the hell… I paid my fee and changed, like a chubby Clark Kent, into my drag suit and parka. Game on.

We motored out to Kirby Cove on the Silver Fox, 24 swimmers and a gaggle of paddlers. The swim was scheduled to start just before slack tide at the Golden Gate (0832), building into a 4.7-knot flood (1134).


Exact water temp is unknown because the NOAA-Crissy Field buoy was out, but I’d guess it was about 57F (13.9C). Air temp was mid-50s at the start, becoming warmer and quite sunny as the morning progressed.

Once everyone had swum into shore from the boat, we set off in two “pods” – the six fastest swimmers at 8:15, preceded by everyone else at 8:11.  Heading out I took too straight of a line into the channel, thinking it would get me into the current faster. This was stupid: I should have angled straight for mid-span of the Bridge (there wasn’t much current then anyway). That’s precisely what the leader did, and by the time I corrected my course, I was 25m behind.

Red line = my course. Blue line = straight tangent to Golden Gate Bridge mid-span

We were not assigned paddlers on a one-to-one basis, but within a few minutes I noticed Hank and his son shadowing me in a tandem kayak. I was treating this as a self-navigated swim, but they were a comforting presence and definitely helped keep me on a straighter line with less sighting.

I reached the Golden Gate Bridge, a bit north of mid-span, in 17 minutes, 30 seconds (0.77 miles, 2.64mph). Around this time I lost track of the leader. Oh well, I thought: I’m not trying to race this anyway. Not a race!! 

I saw a wooden rowboat off to my right (toward south tower), but no swimmer. Turned out he was there, but on the other side of the rowboat.

Onward I swam, angling across the shipping channel toward my destination. Meanwhile, it was turning into a glorious day! I felt the warmth of the sun on my back, and the Bay was as calm as it ever gets.

I watched the Palace of Fine Arts come and go, and soon the piers of Fort Mason came into view. Hank was motioning me to head further in, but I ignored him until around Gashouse,  taking my chances on missing the Opening. I did have a bit of a scramble right at the Opening – the flood was really picking up now – but I made it safely at 1 hour, 12 minutes, 12 seconds elapsed time (54:42 for the Bridge-to-Opening segment, 3.2 miles, 3.51 mph).


Once inside the Cove, I saw no one behind me so I took a very relaxed pace toward the SERC beach. This, along with my failing to account for the effect of the flood inside the cove (pushing me too far east), caused a very close call at the finish.

As I approached the SERC pier, I finally noticed I was off course, and started crabbing back. At the same instant, I noticed Darrin suddenly almost even with me, sprinting straight in to the finish. He almost got me. I found a final burst of speed and cleared the water first.

It’s not a race, people. Not a race!

I’m sure the timekeepers were highly entertained. Final time 1:17:06.

And a fine warm-up for Bay to Breakers…
