Entry Requirements

Runners must meet one of the listed qualifying standards off the race website. The entry fee applies to all runners regardless of qualification time. Runners interested in applying should inquire:

USA 24 Hour Qualifier

The Desert Solstice 24 Hour Run will serve as an ideal qualifier for the USA 24 hour national team to compete in the world 24 hour championship.


Laps will be recorded by the MyLaps active transponder system and will be submitted for USATF record purposes. You will be provided with a transponder to wear around your ankle.

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. Every 4 hours we will change the direction of travel. Your number of laps, distance, and race will be shown on an electronic display near the start.

Race Course

The race route is a certified 400-meter all-weather track located at Central High School in Phoenix, AZ.


Entrants will receive results for their 100-mile split (if they reach that distance) AND the 24-hour. E.g.: This means if you're applying to run a 50KM world record and stop at that point, your ultra signup will reflect 50KM distance for the 24-hour event. All entrants will be registered for the 24-hour event.

If you would like to join our volunteer team, we are looking for help with event setup, main aid station, timing, and event breakdown.
