Virgin Waters: Distances between and around the Channel Islands and the U.S. Mainland

The biggest season in the history of the Santa Barbara Channel Swimming Association officially began yesterday, with a previously “undisclosed” relay crossing from San Clemente Island to the mainland – a distance of 54 miles.

Compared to the most famous Channel Island – Catalina – the remaining seven Channel Islands are still relatively virgin waters for marathon swimmers. Here are the number of successful solo swims, by island:

  • Anacapa to mainland (12.6 miles) – 25 swims by 23 individuals
  • Santa Cruz to mainland (various distances) – 8 swims
  • Santa Rosa to Santa Cruz (6 miles) – 2 swims
  • Santa Barbara to mainland (37.7 miles) – 1 swim
  • Santa Rosa to mainland (27.5 miles) – 1 swim
  • San Miguel to mainland (25.9 miles) – 1 swim
  • Anacapa to Santa Cruz (5.6 miles) – 1 swim

There are 80 possible swimsย between and around the eight Channel Islands (including Catalina) and the U.S. mainland. Only 11 of those have been conquered by solo swimmers. The following table shows the distances (in statute miles) for each of the 80 swims:

Notes:

  • Abbreviations: ml = mainland; SM = San Miguel; SR = Santa Rosa; SCru = Santa Cruz; Ana = Anacapa; SN = San Nicolas; SB = Santa Barbara; Cat = Catalina; SCle = San Clemente

  1. I love looking at cool charts like this. It takes a lot of time to put something like this together but makes it incredible easy for people to do research and analyze…

    1. Thanks Jamie, glad you like it! Clearly some of these swims will probably never be done, but it’s fun to think about!
