Desert Solstice Track Invitational
Desert Solstice is an elite level ultrarunning track meet held at Camelback High School in Phoenix, Arizona on December 19-20, 2026. The event features timed and fixed-distance competition on a 400 meter all-weather track with zero feet of elevation gain per loop and a maximum site elevation of 1,123 feet.
The event includes these distances
- 24 Hour timed event
- 100 Mile fixed distance
Entry to Desert Solstice is by invitation or qualification only and the 24 Hour / 100 Mile field is limited to a small number of runners. Electronic chip timing records laps at the start/finish and the 200 meter mark for USATF and IAU record purposes, and results for timed events show the furthest distance reached. For the 24 hour event a separate 100 mile split is indicated while all results are listed under the 24 hour category.
A fully stocked aid station will be available throughout the race, and portable restrooms will be on course. Runners are assigned paired 10 by 10 canopy spaces with two tables and chairs for hydration and nutrition. Pacers are not permitted. The event maintains specific track etiquette and USATF rules for record attempts and equipment, and prize money is awarded to athletes who meet listed performance standards.
Desert Solstice has a history of national and world records set at the meet and uses live tracking for split points during the race. Visit the organization's website for the most recent information.
