oh man... what a tough first century... yep, sounds like you actually had heat exhaustion... I am much like you in that I have ridden when I should have sagged in... mostly cause I'm stubborn and don't want to quit! BUT, I also paid the price because on that ride I blew out my ITL Band and ended up off the bike for a couple months healing... tough lesson, but learn it I did...
