Black Toenail Friday Half Marathon and 7.5 Miler

Join Trivium Racing for our Thanksgiving weekend tradition! Relax on Thanksgiving and hit the trails for your holiday race on Black Friday with a Half Marathon or 7.5 Miler. Join us on the beautiful, well-groomed trails of Proud Lake State Recreation Area and leave the crowds to the mall! One of the best parts about Black Toenail Friday Half and 7.5 Mile is sleeping in. With an 11:00 AM start time, you can relax and enjoy Thanksgiving dinner knowing you have plenty of time before the starting gun goes off the next morning. The Half Marathon is a two loop course; the 7.5 Miler completes one of those laps. Black Toenail Friday is the 6th race in the 6-race Trivium Michigan Mega Medal Series!
