Lots of nice trails. Best to check out a map in advance as there are lots of variations. This is all from recollection - haven't been back for three years though. My pick would be to start just south of the Rec. You should be able to park along Chestnut. There is a little trail that cuts through some houses and drops into the western end of the woods that are just south of campus and just west of 27. I guess you could just park in the parking lot for this woods - can't recall what it is called. From there, head east under 27. The trail goes out past the big parking lot to the east of campus and under this highway. Lots of other options from here with rolling hills on tight singletrack. I recall one trail that always popped up a hill to a pond and then we'd always exit the trail system far north of campus, past Yager Stadium, take the road back in to town, and then roll the downhill back to the Rec. Sorry can't recall the names, but if you can just get to the trail system, you should be fine.
