Coming November 30, 2019. OK, it’s almost a tradition to overeat on Thanksgiving, so how about making another tradition: work off some of those extra calories the day after? Then the MCRR Turkey Burnoff is just what you need! The Montgomery County Road Runners host a 5 and 10 mile race at Seneca Creek State Park in Gaithersburg, Maryland. It’s a scenic course through the woods on paved paths with gently rolling hills for a bit of extra burn. Run off those extra T-Day calories at the MCRR Turkey Burnoff!
