I'm going to do an adventure race in Virginia this April and it includes 60miles of mountain biking. Hybrids are not permitted. There's a combination of wide open trails and single track. I'd like to keep the cost around $1,000, which is a lot for me and I don't want to purchase the wrong bike. I'd like to do a lot more of these races.
I just hit 40 and I'm hopeful these races will help me beat father time :)
