Seriously, this saturday I'm riding my first century. I have been training, did an 80 mile ride recently. Ride every day for 1 to 2 hours a day. Read all the books, etc. But last saturday I rode around 45 or 50 miles. Midway thru a hill, my legs felt like lead. One of the guys talked me up the rest of the hills, another one gave me one of his energy gels. Anyway, I made it but I felt like a whimp. So now that I have a century on Saturday, I'm getting paranoid.

1. I did not eat before I rode on Saturday would that have done it?
2. Am going with a group and they want me to draft behind them, but should I suggest we ride at my pace not theirs?
3. Should I still go to the gym this week? In addition to riding 1 to 2 hours a day?
4. I'm thinking I should not ride the day before?

Any advice you could offer would be most welcome.
