Who Should Run This Race?

This race is ideal for trail runners who want a moderately challenging half marathon with significant elevation and altitude. If you’re comfortable running at higher elevations and want a race that’s less crowded but still well organized, this is a solid pick. It also suits those combining a race weekend with outdoor adventures in Wyoming, Montana, and Idaho.

Getting There

The race start is on Old Airport Road near West Yellowstone, Montana, but many runners opt to stay in nearby Island Park, Idaho. Island Park is about a 45-minute drive from the start and offers more affordable lodging options. Volunteering at packet pickup or on race day is encouraged and adds to the community feel. Plan for an early morning drive to the start to ensure smooth parking and easy access.

Race Morning

Race morning temperatures were around 38°F, so gloves and layered clothing are recommended. The race is a cupless event, so bring your own hydration system. Plan to leave early to account for the 45-minute drive from Island Park and secure parking near the start line. The early start and cold weather make preparation key.

🌄 Course & Elevation

The course is primarily trail with rolling hills and some rocky footing, requiring attention to footing and pacing. Elevation ranges from approximately 6,600 to 7,000 feet, with a total gain of 671 feet. The altitude presents an additional challenge, so be sure to acclimate properly and adjust expectations accordingly.

🏅 My Result

I finished in 1:37:41, placing 9th overall and 2nd in my age group. The race was a solid test of endurance and altitude adaptation, and I was pleased with my pacing and effort given the conditions.
