Dan, I was SHOCKED at how challenging the swim was (400 lousy meters.) This is after putting in 1600 hard meters in a pool a few days prior with no problem. I will take your advice and respect the swim, always.
Oh, and I must mention. I received my time results and I burnt almost 13 minutes in T1 getting out of the suit, shoeing up, and looking for my GPS device! I think I can improve on that.
