There is a 3.5 mile race loop with some sweet singletrack and some steep drop in hills. This is a easy race loop for most racers but I think overall this trail with the stream crossings and drop in hills will get the average rider.
In Gorham, Maine at the corner of RT. 25 and RT 114 you will find University Of Southern Maine. If you can find the baseball parks at the school you will find the trails. You will need a parking pass to park at the school. There is on street parking in downtown Gorham only a half mile from the school.
