The Biology Trail offers some steep climbs, fun downs and is an all around great place to sneak off for a lunchtime or after work ride or just to train in general. There are several short loops off of the main trail. For the more experienced riders there are a few jumps, some step ups and drop offs as well as creek crossings. On top of the ridge there is 2 miles of boulders. Good luck!! Get your trail map at https://www.southern.edu/biology/Documents/biology.trail.pdf because you will need it.
