Beaverhead Endurance Runs

The Beaverhead Endurance Runs are true mountain races. The route is rugged and challenging over varied terrain all at high altitude. Those who participate, please be prepared. We want all to finish and enjoy this event, thus the 55K has liberal cutoffs, but you still need to be prepared.

Both races are point to point and take place predominantly on the Continental Divide National Scenic Trail (CDT) and the Continental Divider, between Idaho and Montana. You’ll experience some of the beautiful skree fields, but not the cliffs, so we will drop off the Continental Divide at mile 54 and descend into the head waters of Bohannon Creek and onto the finish line. The 55K race covers the second half of the 100K race, starting near the Lemhi Pass aid station.

Runners will always be at a high elevation in the mountains, following the natural elevation changes along the divide. Runners do not descend into the deep creek and river valleys that border the course, except when they drop off the divide to the finish. This course has a good mix of terrain, including climbs, descents, smooth trail and technical sections.

This high, remote, rugged and scenic section of the Beaverhead Mountains is rich in history. The birthplace of Sacajawea, the home of the Lemhi-Shoshone Indians, the Lewis and Clark expedition, and gold mining are just some of the historic highlights from this part of the Rocky Mountains. The landscape along the course is nearly untouched and looks like it did over 200 years ago when Lewis and Clark crossed the divide and the Shoshone traveled to and from their winter and summer grounds over Lemhi Pass.
