About the Betsie Valley Trail Run Half Marathon
North Mitten Events runs this small September race from the Webber Sports Complex in Thompsonville, with 10K, 5K, and one-mile options alongside the half. A share of the proceeds goes to the Friends of the Betsie Valley Trail, the group that keeps the corridor maintained.
Course
The route follows the former Ann Arbor Railroad grade, so it is flat and straight by trail-race standards. The firm aggregate surface works fine in road shoes, and the out-and-back passes wetlands, pine and hardwood forest, and crossings of Dair Creek and the Betsie River.
Race-day weather
Late September in this part of Michigan usually starts in the 40s and warms into the 60s. Tree cover shades much of the trail, and soft spots or wet leaves after rain are the main surface concern.
