The event is a 24-hour track race with a variety of race options. Additional options include 50-mile, 12-hour, 50K, 6-hour events, 26.2-mile, and 13.1-mile. Time limits for the distance races are 24-hours for the 100-mile race and 16-hours for the 50-mile race. We recommend dual registration for the 24-hour and 100 mile race if you are concerned about the 24-hour cutoff for the 100 mile race. Participation will be limited to 100 competitors, and registrations will be filled in the order they are received.
The race is a qualifying event for the 2019 IAU 24-Hour World Championship. The race is intentionally held on a certified track to provide participants with a flat, cushioned surface to achieve their best performance. All efforts will be made to respect the endeavors of competitive athletes while promoting safe and fun environment for all participants.
Laps will be recorded by electronic chip timing and will be submitted for USATF record purposes.
You may leave the track at any point in time during the race, but you must return to the same place before continuing. You may not leave and return directly by the timing equipment, to avoid double counting a lap. Your number of laps, distance, and race will be shown on an electronic display near the start.
Awards will be given in Male and Female categories for the 24-Hour, 50-mile, 12-hour, 50K, 6-hour, 26.2-mile, and 13.1-mile overall individual winners and 24-hour overall relay winners. Belt buckles will be provided to 24-Hour and 50-mile finishers.
All runners will receive an event specific race shirt, and all finishers will receive a finisher medal.
