Who's going to Prairie On Fire Backyard Ultra?

Free. You can start with nothing.

Free, and always will be. NavRun makes money from race-day planning for runners who want it, never from this. Ultras change constantly, sometimes the morning of. Always confirm with the race director and the official website before you rely on anything here.

The course

Where it goes backyard · 1 aid station

One yard is 4.167 miles and starts on the hour. The day yard begins at the White River Campground pavilion, crosses the White River on a historic fixed truss bridge, and runs groomed, mostly crushed-gravel trail through Koteewi Park. From 8 PM the night yard starts at the same pavilion and runs out and back on an asphalt trail along 234th Street, past Indiana farmland. Runners camp next to the start corral and go back to it every hour.

Climb per yard as the organizer lists it: 62 ft on the day yard, 69 ft on the night yard. The day trail can flood. An alternative day course is promised if there is significant rain, to be announced closer to race day. Slower runners must let faster runners pass.

The race

What this one is

Prairie on Fire is a last-person-standing backyard ultra at Koteewi Park, run by Meshingomesia Track Club with Hamilton County Parks. Every hour on the hour, runners start a 4.167-mile yard. Daytime yards run on crushed gravel and dirt trail through the park. From 8 PM the yard moves to a paved out-and-back along 234th Street. It goes until one runner is left. Entrants have gone as few as one yard and as many as 43, and a runner who has never gone past a 5K can come and stretch it by a yard or two.

The 2026 edition was the fifth annual. Results are posted back to 2022. The organizer's 2027 listing calls the next one the sixth installment.

I keep this catalog because the information is scattered and hard to trust. Telling you when it moves is the same job.
