Coalfields Backyard Ultra

Coalfields Backyard Ultra

Coalfields Backyard Ultra is a Backyard Ultra-sanctioned, Last Runner Standing event held on Memorial Day weekend, with the main race date on May 22, 2026, in Williamson, West Virginia. The event takes place at Southern West Virginia Community and Technical College and uses an out-and-back loop format where distance accumulates each hour.

Course

The measured loop is 4.1667 miles total, laid out as 2.08 miles out and 2.08 miles back. The route uses asphalt along the West Williamson flood wall river path, passes Williamson PK-8 school on a gravel road, goes through a neighborhood, and passes a recreation area/community center to a turnaround at 2.08 miles. The course is described as very flat and will be marked with cones, arrows, and other markers. One section may be rerouted if saturated from heavy rain.

Logistics and rules

Participants return to the start/finish after each loop. There is a single aid station at the start/finish offering water, hydration, food, and porta potties; personal aid at the start/finish is allowed but no personal aid is permitted on the course. Porta potties will be placed at both ends of the course and the college tech building will be available for restrooms and food. Camping is allowed at the start/finish for a fee of $10 per day. Loops begin every hour and must be completed within that hour; the winner is the last runner to complete a loop. Timing, live results, and a live video feed will be provided by Brunning Endurance Timing. Organizers are seeking Bronze status for 2026.
