Course Details

A large section of the 30 km and 43 km courses takes place on very challenging backcountry trails. These sections are rocky, have plenty of roots, and feature steep ascents and descents. They can be slippery if wet. Runners are expected to be self-reliant in these sections, with distances between aid stations potentially up to 17 km. The event is described as a "graduate" level trail run, best suited for runners with prior trail experience.

Logistics and Registration

The event is capped at 250 participants. Registration includes a race bib, a t-shirt, a custom finisher's medal for those who complete the race, and access to food and drinks at aid stations. The race fee does not include park admission; participants arriving on race day must pay for a day pass at the park gate. Visit the organization's website for the most recent information.
