Yeah, I feel you about a DNF. But you made a judgment call that would let you stay well enough to race more races in the future. IMO, the hardest part of racing is not in the finishing, its doing the right thing when you know you should not start or finish even though your ego is screaming at you to go on and just do it, to h*ll with all consequences.

Someone recently shared some advice on drinks during hot weather, apparently, slushies are more effective than just chilled drinks when racing or training in the heat. If you ever manage the logistics for that, it might be a good thing to try. =) Here's to plenty more terrific races in the future!!
