Bleak Midwinter Endurance Run

The Bleak Midwinter Endurance Run is a timed endurance event on January 23, 2027, at Sac River Mountain Bike Trails in Springfield, MO. The event offers four timed run options.

  • 12 Hour run
  • 6 Hour run
  • 3 Hour run
  • 1 Hour run

The course is a roughly 4.15 mile loop of moderately technical single track with rocks and roots, passing through hardwood forest and small glades. The loop is waymarked with permanent signs and temporary flags and ribbons. Runners will begin the event running in the same direction and, after completing the first lap, may run subsequent laps in either direction. Each lap has about 400 feet of elevation gain. Only completed laps count toward mileage and runners must check in between each lap to have laps recorded.

Aid and logistics are centralized at the Base Camp Pavilion aid station located at the start/finish area; food, drink, warmth, crew tent space, port a potties, and first aid are provided there. Packet pickup is scheduled at Sac River Mountain Bike Trails on the event date. Registration fees are listed per event and range from $35 to $95 depending on the timed option. The event proceeds support Headington Hill Classical Academy, a 501c3 nonprofit; refunds are not offered except for cancellations for safety or other factors beyond the organizer's control. Dogs are allowed on leash; cats are not permitted. Visit the organization's website for the most recent information.
