I made a couple of nutrition mistakes Saturday morning that killed me: I ran out of milk (so no cereal ), so I had a yogurt. I also put grape gatorade in one of my bottles. It wasn't hot, maybe high 60s or low 70s, but horribly humid. I had to pull over for a while to keep from throwing up. I had a time limit as one of my friends was picking me up for a little trip to Pittsburgh, but I still got around 8 miles in with hills. I improved my average speed too.
