About the race

Dizzy Horse Backyard Ultra is a winter ultramarathon in Idaho Falls, Idaho, held at the Bonneville County Exhibition Hall and Sandy Downs Park. The race is a Backyard Ultra: runners complete a 4.167-mile loop every hour on the hour, until only one person remains (the Last Horse Standing). The course features grass, dirt, horse racetrack, sand, and pavement, with roughly 40–80 feet of elevation gain per lap.

The event emphasizes a social vibe with an indoor transition area, deluxe aid stations, and upgrade options, plus live tracking and a strong crew/volunteer network; it’s a Bronze Qualifying Backyard Ultra. Visit the organization's website for the most recent information.
