This is an event for experienced mountain runners, as it is unmarked and almost unsupported (there is only one aid station at the turn-around). This CANNOT be your first 50 miler. There are many cairns and you primarily stay on a ridgeline, but with no course marking it is still possible to get well off-course. You will need to carry supplies for five to nine hours of running, and once you are out on the course there is no easy way out until the turnaround.

This 45 mile out-and-back course takes place in the traditional territory of the Apsaaloké, Tsėhéstáno, & Niitsitapi peoples. You will be running at altitude (mainly at or above 9500 feet) with a spectacular views of the Paradise Valley, Absaroka Mountains, and Spanish Peaks. Elk, mountain goats, and bears (both black and grizzly) may be seen. Hand-drawn and topographic maps are available at the website.

The event starts and finishes at the Hyalite Creek Trailhead. It is on 100% singletrack trail, with one significant climb to Hyalite Peak (10,300 feet) and multiple short steep climbs totaling close to 11,000 feet total vertical gain. It is a deceptively difficult course due to the high elevation, exposed terrain, and rough, rocky trails.

There will multiple small stream crossings in the first (and last) 7 miles. There is a lake at 11 miles (and 39 miles), a very small spring a quarter mile later, and typically a number of snow patches along the course. Water has certainly been frequented by wildlife, so a filter or other water purification is recommended. Cutoff time is 7.5 hours at the turn-around cabin. Please note that no dogs are allowed on the course, and please leave your speakers at home (not everyone wants to listen to your music!).
