Trail is excellent for training. One steep climb after another with some really good downhill. Very rocky. Trail shared with ORV's so be careful. (They mostly ride weekends and you can hear them coming for the most part.)
East on 565 to Oakwood exit; Oakwood west to Meridian St; north on meridian to Colonial Hills Elementary (on right); park in school parking lot; trail starts on oppostie side of fence; follow to RR tracks and cross over; Main loop goes either direction and is marked white; alternate trails in orange (expert level)
