Bleak Midwinter Endurance Run

The Bleak Midwinter Endurance Run is an annual timed endurance event held at the Sac River Mountain Bike Trails near Springfield, Missouri. The race features a challenging 4.15-mile loop of moderately technical single-track trail with rocks, roots, and about 400 feet of elevation gain per lap. Participants can choose from four timed options: 12, 6, 3, or 1 hour runs.

The course winds through hardwood forests and glades, with runners starting counterclockwise but allowed to switch directions after the first lap. A single aid station at the start/finish provides food, drinks, and support. The event offers custom swag and special awards for 50K and 50-mile finishers, with proceeds benefiting the Missouri Baptist Children's Home.
