Prairie On Fire Backyard Ultra

The Prairie On Fire Backyard Ultra is Central Indiana's only official backyard ultra event, held at Koteewi Park in Noblesville, Indiana. The race features a unique format where runners complete a 4.167-mile loop every hour, starting at 8 am, with each loop beginning on the hour. Participants continue running loops until only one runner remains.

The course includes a mix of dirt and gravel trails through Koteewi Park and a paved out-and-back section along E 234th Street. The event welcomes runners of all levels, from those aiming to beat a 5K personal best to ultra-distance veterans. The 2025 race marks its 4th annual running.
