This is a link-up of the best singletracks in Groton Town Forest. While it loops back and forth to get to a total length of 10 Miles it does not repeat any trial. Some double tracks riding is necessary to connect the singletracks.
The hardest section comes at mile 1 where there are a 2 challenging climbs. After that it gets a bit easier but there are many more short downhills and climbs to come.
