I crapped out after lap 3. No way in hell could I have gone on it was so hot. Tell you what though, I have never seen so many people say f-this and call it a day so early in the race... less than 20ish 3's completed the whole thing. I headed back to the feedzone (right across from the rifle range) and assumed water duties with a couple of people we knew.
My teammate managed 4 laps and someone tried to hand him a beer as he was nearing the finish line.
FTR- the 80 mile Lake County race was cake compared to this.
