Dedicated to the landscape

Tucked away in southwest Wyoming, below the Tetons and above the Wasatch, sits the Wyoming Range. This stretch of mountains is home to the Wyoming Range National Recreation Trail (WRNRT), a 75-mile stroll through some of the most beautiful high country imaginable. The WRNRT sits at the heart of the Wyoming Range 100, giving runners the opportunity to immerse themselves in wilderness while still running a supported race.

Built for a grueling finish

With 24,000’ of climbing and an average elevation of 8,500’, prepare yourself for a grueling run that offers few breaks. Don’t worry too much, though — time is on your side. With a generous 48-hour cutoff, we want every runner to complete the 108-mile epic. We designed the Wyoming Range to be challenging but finishable.

Hardock 100 qualifier

This is a graduate-level race with no shortage of challenges. You'll run in grizzly country. You'll have ten-mile stretches between aid stations. You'll cover rough and disappearing trail. You could run through snow, lightning, and white-out conditions. At this race, you must be prepared for everything.
