mtbdarby,

I also think it is doable, but it depends on the type of terrain, too. At the end of last summer I did my first century ride in the area, which is basically flat. I was *exhausted* and my hands were sore (aluminum frame) and a bit of lower back pain, but I was fine. I rode almost every weekend, an occasional ride during the week; my longest ride prior to the century ride was 75 miles. I was, however, jogging 3-4 miles three times per week. During the century ride, I did stop at every rest stop, stretched and ate.

The one thing I have not figured out is what to eat after the ride. I was ravenous during the 48 hours that followed the ride. And I was very tired the day after.
