Dirtworx MTB Fest 2026

About the Event

The Donut Run 5k is a unique, challenge-based fitness event scheduled for Saturday, April 25, 2026, at Ada Hayden Heritage Park in Ames, Iowa. This annual competition combines traditional distance running with a strategic eating element, where participants earn significant time deductions from their finishing results for every donut consumed along the 5.0 km course. The race is known for its lighthearted atmosphere and the infamous "Chucky Rule," which requires runners to keep their donuts down until crossing the finish line to maintain their time bonuses.

Event Logistics and Participation

Race day operations begin at 8:00 AM at 5205 Grand Avenue with packet pick-up and same-day registration available for those who missed the online window. The race officially starts at 9:00 AM, looping through the scenic lakefront trails of Ada Hayden Heritage Park. The scoring system is tiered, meaning the time bonus per donut increases as participants consume more, incentivizing high-volume eating for competitive advantage. The awards ceremony is scheduled for 10:30 AM, or as soon as the complex donut-adjusted results are tabulated by Race Director Kyle Swenson and his team.
