The Eliminator is a track race with a straightforward rule: complete 20 laps, and after each lap, the final finisher is eliminated. Runners receive a set recovery time between laps, distinguishing it from a continuous 5,000-meter race; it is a recurring challenge of speed, nerve, and timing. Mike Roberts designed the format for runners competing from 800 meters up to 10K, suiting athletes capable of quick laps and sustained pressure.
Events take place on standard tracks, with scheduled locations including Hillsdale College and Kearney Catholic in Nebraska. The race embraces the concept of a "practice champion," offering runners who excel in training a direct competition where each lap counts. As one runner exits each round, the field diminishes in a manner spectators can easily track without needing lap splits or complex scoring. Organizers also encourage teams and communities to host their own iterations, including for fundraising, allowing the format to extend beyond official events.
