Prairie On Fire Backyard Ultra - September 12, 2026
Prairie On Fire is the fifth annual Backyard Ultra held at White River Campground in Noblesville, IN, with the site address listed as 11299 E 234th St. The event is organized by MTC and Hamilton County parks and is scheduled for September 12, 2026.
The race uses the Backyard Ultra format. Participants run a repeating loop of 4.167mi that must be completed within an hour; those who complete a loop may begin the next loop. This cycle repeats until only one runner remains.
The loop combines terrain types. Each circuit begins with a dirt and gravel day loop through Koteewi Park and includes a paved out-and-back section along E 234th St. The course is described as identical or very similar to the previous year’s layout.
Additional event notes include a registration deadline of September 10 at 11:59 PM ET. The organizer notes that in 2025 more than 20 runners completed over 100 miles at this event. The description avoids specific start times and focuses on course, format, location, and key dates. Visit the organization's website for the most recent information.
