Advise needed for race day swim cramp!
I've just completed my first 70.3 (first triathlon full stop) and am now starting training for the next one. My problem is with the swim, im not the best swimmer or the fastest and not having any experience of swimming in a group didn't help (yep didn't follow that advice either).
So started the swim, couldn't get a rhythm so reverted to breaststroke and moved to the outside of the pack (I had already positioned myself for the 55min finish group). My intention was to swim like that to the halfway mark then when the group had dispersed brake in to front crawl but the second I did my right calf completely cramped up, so I swam arms only until it freed off then had another go, same thing, so ended up swimming the entire course breaststroke! I finished in 59 mins so quite surprising for an inefficient stroke, but no good log term as just sapped my energy levels.
so my question is any advise as to what the cause is and how to stop this happening? I have read about causes but nothing seams to fit. Any advise welcome.
