Last Herron Standing Backyard Ultra

Kalispell, United States • 1-2 Aug 2026

Last Herron Standing - Backyard Ultra

The event is a backyard ultra held at 2310 Foys Lake Rd, Kalispell, Montana, over the dates 08/01/2026 to 08/02/2026. It uses repeated loop laps and tests endurance through repeated hourly laps rather than a fixed total distance.

The solo format is a last-person-standing endurance race. Participants run a 4.167-mile loop each hour; the loop repeats hourly and continues until only one runner remains. The solo entry fee is listed as $100 early and $125 late. The event description notes there is no set mileage and the runner decides how far to continue.

The team relay follows the same lap rules with a 24-hour maximum. Teams are typically 2 to 4 people, and the listed competitive relay distance is 100 miles. If multiple teams finish at the same point, the fastest team wins. Teams may also register as non-competitive Fun Run teams and may include any number of participants. The team fee is listed as $50 per person early and $70 late.

A separate kids fun run covers 3K with a fee of $10. Distances and formats described above are the core event options for participants. Visit the organization's website for the most recent information.
