Scout Mountain Ultras is an annual trail running celebration held in early June in the mountains of Pocatello, Idaho. With distances ranging from 23 miles to 100 miles, the event is designed to welcome runners of all experience levels, from first-time trail runners to seasoned ultramarathoners. Held across rugged and scenic terrain, the event blends physical challenge with spiritual renewal, celebrating the deeper meaning of running and time spent in nature.

What makes Scout Mountain Ultras truly stand out is its commitment to environmental sustainability and community equity. Race directors Luke and Tanae Nelson view the race as an “environmental event with a running problem,” donating proceeds to conservation organizations, reducing waste, and partnering with grassroots environmental groups. The race also prioritizes inclusivity, reserving 50% of spots for women, femme, and non-binary runners, and actively fosters a welcoming space for all identities.

Participants can expect stunning aspen groves, wildflowers, and expansive ridgelines—along with a strong community vibe. While crew access is limited and tightly managed for environmental and safety reasons, the event is well organized with detailed logistics and a clear focus on runner and volunteer care. It’s more than a race; it’s a gathering of kindred spirits who share a deep respect for nature, movement, and each other.
