Marathon

I'm training with CARA (www.cararuns.org) for the Chicago Marathon. Honestly, I haven't had the time to follow the training schedule. However, I ran the 18 miles today with the 10:00 pace group. Actually, we run around 9:45. I couldn't keep up that pace more than probably 16 miles and had to return to the 10 min pace. Luckily, I had someone to slow down and run with. Anyway, while down at 67th street, I had to Gu - Espresso Love. I looked at it and gagged. I mean eyes watering, burps, etc - true gagging. If I don't look, i'm ok.
