It'g going to depend on the course and the conditions, so you'll probably want to have 2-3 options. Check this out-

I'm about to build a 42-18. I'm going to use that for baseline, and adjust as I need. Really, I'm just using what's around the basement. I think 39-18 is probably in my future, but I wanted to try out the 42t biopace ring...

i ran a 38x18 most of the time, a 38x20 for hillier courses, the 18 can get pretty rough after 45 minutes when you hit those steep climbing sections, spinning faster is always an option with the 20.

I've got a 46X20 that I use on the fireroads, which seems a little bit steep for the bigger climbs but perfect for flatter areas and more moderate climbs.
