I am putting this up specifically for John! (that and the fact I just looked and my marathon training program has me running a half marathon this exact day. Sigh).
This is a super fun but really quite tough trail race out at Fallasburg Park in Lowell. You have the option of a 5k, a half marathon, and a full marathon. It's a small race with good people and snow cones at the end, which I admit, gets me there more than half the time! Plus, the race fees are ridiculously good--$25.00 for the half if you register before 7/20.
