The course

Where it goes point to point · 11 aid stations

No official GPX on file yet. These are the aid station coordinates, not the trail. Have the GPX? Send us the link.

A point-to-point 100-miler along the Wyoming Range National Recreation Trail from Middle Piney Lake to the Box Y Ranch, with three cutoffs and aid stations about ten miles apart.

The Wyoming Range National Recreation Trail is faint or missing in places, mostly above timberline, and runners follow pin flags and the course GPX. Aid stations are about 10 miles apart, there are many stream crossings, and the race is in grizzly country, so bear spray is required.

I keep this catalog because the information is scattered and hard to trust. Telling you when it moves is the same job.
