Bleak Midwinter Endurance Run
The Bleak Midwinter Endurance Run is a timed endurance event held on an approximately 4.15 mile loop at Sac River Mountain Bike Trails near Springfield, MO. The event offers four timed options: 12 hour, 6 hour, 3 hour, and 1 hour, and includes packet pickup at the trailhead on January 23, 2027.
The loop is moderately technical single track with rocks and roots, passes through hardwood forest and small glades, and is marked with permanent signs plus temporary directional signs, survey flags, and ribbons. Each lap has roughly 400 feet of elevation gain. All participants begin the event running the same direction; after the first lap runners may choose either direction, but must check in between laps. Only completed laps that are checked in count toward a runner's total.
A Base Camp Pavilion aid station at the start and finish provides food, drinks, warmth, and support. There is space for crews to set up tents nearby. Port a potties and first aid are located at the pavilion.
Registration fees are stated by event: $95 for the 12 hour option, $75 for the 6 hour, $55 for the 3 hour, and $35 for the 1 hour. Registration closes January 17 at 11:59 PM CT.
