Wyoming Range 100 Mile Endurance Run Big Piney, WY   Aug 7, 2026

The Wyoming Range 100-Mile Endurance Run is a classic point-to-point along the Wyoming Range National Recreation Trail. Rugged, relentless — and finishable.

The Wyoming Range Trail travels north-south for 75 miles through some of the most beautiful high country imaginable. We placed the WRT at the heart of the Wyoming Range 100 to offer seasoned ultra-marathoners the opportunity to feel immersed in wilderness while still running a supported race. With approximately 24,000 feet of climbing and an average elevation of 8,500 feet, you should prepare yourself for a grueling run that rarely offers breaks.

But don’t worry too much — time is on your side. We designed the Wyoming Range to be challenging but “finishable.” With a relatively generous 48-hour cutoff, we want every runner to complete the 102-mile journey from Big Piney to Hoback.

The point-to-point course runs south to north and has a slight “downhill” profile. Runners will climb approximately 24,000’ over the 100-mile course. The course’s high point of 11,378’ comes early, at mile 8.0. The finish line is the lowest point at 6,214’.

Although we designed the Wyoming Range 100 to be tough, we did not design it to have a low finishing rate. We want every single runner who starts the race to finish the race. To help make this happen, we only have two cutoffs on the course, both of which we believe are manageable:

McDougal Gap (43.1) — 3:00am Saturday (20 hours)
Finish (100.0) — 7:00am Sunday (48 hours)

Every starter will receive a sized and embroidered Stio jacket. Stio is a Jackson-based outdoor apparel company, and they make high-quality, technical gear.

All finishers will receive a custom-made belt buckle that reflects the spirit of the Wyoming Range and commemorates our event.
