Fast-forward to last Friday, I went to the Bay to try my new swim progress and BAM! it happened again: about 200 yards in my arms are just so tired. I only managed to get 1800 yds in before my left arm was just gone. I couldn't finish the pull, my tricep was just dead.
I have an Xterra wetsuit, one of their low-end models (Vortex 4), and I had this issue last year too, and I thought that with all the swimming I did over the winter (I still swim 4 times per week, about 2500 yards per session, mixture of speed work and endurance, I swim with a Masters Club). But a lot of my friends have similar or the same wetsuit, in fact, a really good swimmer (25min HIM) swims with us and he owns the same wetsuit I have, and he does not have this issue. None of my triathlete friends have this issue.
I went to Xterra today here in San Diego to check if maybe I'm in the wrong size wetsuit. I'm 5'10", and weigh 168lbs, according to their chart I'm an M. They agreed. They offered their high-end suit, the Vengeance:
But before I unload even more money into this sport, I'm trying to figure out if flexibility of the wetsuit really IS my problem, or if it's something else.
Anybody had this issue? How did you overcome it?
