I’m training for IMAZ (first IM) and so far everything is going fairly well except recently I’m having increasing trouble with cramping feet and legs while swimming and a really hard time swimming for very long without getting so cold I have to get out. I’ve never had a problem with cramping before and although I do get cold easily, this has been extreme to the point where I can’t feel my fingers and have to quit. Happens in the pool and open water swimming with wetsuit. Anyone else had experience with this? I’m not sure if its nutrition, fatigue, wetsuit doesn’t fit right (or isn’t warm enough)? Or if I’m just a wimp? At this point I’m pretty worried about swimming 2.4 miles on a 55 degree morning at o’dark thirty.
