Prairie On Fire Backyard Ultra

The Prairie On Fire Backyard Ultra is Central Indiana's only official Backyard Ultra, held at Koteewi Park in Noblesville, IN. The event 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 dirt and gravel loop through Koteewi Park and a paved out-and-back trail along E 234th Street. Suitable for all levels, the race challenges runners to test their distance limits, with past participants completing anywhere from one to 21 loops. The 2025 race is scheduled for September 6.
