The Corn Belt Running Club 24 Hour Run, taking place from Saturday, May 2nd to Sunday, May 3rd, 2026, in Davenport, IA, offers a truly distinctive challenge for ultrarunners. This historic event, known as the longest-running fixed-time race in the USA, invites participants to test their limits over a full 24 hours on an all-weather 400-meter track at Brady Street Stadium. Embracing a "go-as-you-please" format, runners, walkers, and even crawlers are all welcome to see how many miles they can accumulate.

What truly sets this race apart is its intimate atmosphere and unwavering support. Limited to just 60 runners, the event fosters a strong sense of camaraderie, where participants interact closely with dedicated manual lap counters who not only track mileage but also provide invaluable encouragement throughout the grueling challenge. The course is flat, offering a pure test of endurance, and lap direction changes periodically to keep the experience dynamic. Typical race day conditions in early May feature comfortable highs around 67°F and lows around 45°F, with an 18% chance of precipitation.

Runners can anticipate a well-managed event with restroom facilities conveniently located near the track. While the race provides water and Gatorade, participants are encouraged to bring their own handlers and additional aid. Beyond personal achievement, entering this race supports a great cause, with proceeds benefiting the CBRC Children's Running Programs. Finishers receive a T-shirt, and those who complete over 100 km are awarded a plaque, with trophies for the overall male and female winners.
