I recently noted an unforeseen benefit of doing long swims in a short-course pool: It’s easy to monitor your stroke count without counting!
That’s the good news.
The bad news?
Swimming for a long time without stopping in a short-course pool can increase the risk of tossing your cookies.
I assume this has something to do with flip turns, and I also assume it depends on what you’ve eaten recently. I didn’t have a problem in the One Hour Postal last year, but I occasionally do get nauseated during these swims.
It goes with the territory. Just ask Dave Barra, who did a memorably gruesome 30,000 SCY workout at about this same time last year.
