I did my first century last fall and my longest ride going into it was 65 miles. Riding strong on shorter rides, I think, allowed me to do the century at a decent pace even with the additional miles. Also, the first 30 miles were a breeze due to the size and speed of the group like a big peleton just pulling us along. I think we averages 22+mph for that first 30 miles!

Riding with guys can suck but on the other hand, the guys I ride with regularly think riding with me sucks They dont like getting beat by a girl.
