2017 USATF 24 Hour National Team Selection Procedures & Performance List

This event is by invitation or qualification only.

For the 24 Hour/100 Mile, entry is limited to 30 runners total.  At 20 entrants, entry requirements will be tightened.

Runners interested in applying should inquire: hayley@aravaiparunning.com

Spectators are welcome and encouraged for the duration of the event.

Qualification Standards and Entry Fees
Runners meeting one of the listed qualifying standards may apply for acceptance into Desert Solstice.  The entry fee applies to all runners regardless of qualification time, and all runners are eligible to earn prize money for their performances as listed below.  Runners may request acceptance at other race lengths (e.g. 100k, 12 Hour) for comparable performances.

Runners not meeting listed times may petition acceptance to a given standard for other circumstances (e.g. course difficulty).  However, keep in mind the best way to demonstrate competence for a fast ultra is to run a fast ultra, not a difficult one.

Qualifying marks should be recent, preferably in the last three years.

Race Schedule
7:00am Sat – Packet/Bib Pickup
8:00am Sat – 24 Hour & 100 Mile Start
8:00am Sun – 24 Hour & 100 Mile End

There will be a brief race meeting approximately 20 minutes before the start of each race to announce any last minute information.

Laps will be recorded by electronic chip timing and will be submitted for USATF and IAU 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.


For timed events, there is no DNF. Results will show the furthest distance reached via timed checkpoint. Desert Solstice results will indicate a separate 100 mile split but all results will be listed under 24 hour.

Awards will be given in Male and Female categories for the 24 Hour and 100 Mile.  Runners in the 24 Hour/100 Mile are eligible for both awards.

Average highs for mid-December in the Phoenix area are 67 during the day and a low of 43 at night. Record highs are in the upper 70’s and record lows are in the upper 20’s for this time of year.

Important – Weather in Phoenix in December can be sporadic.  Though the weather is usually clear and mild, we experienced light but steady rain for much of the 2011 and 2012 events.  Be prepared with clothing to handle a wet and cold event.  In case of rain, we will have tents available for crews to keep dry during the race.

Personal Space
We will have tables and chairs for runners to share. There is ample space around the track available to set up your own tables and chairs, blankets, or tents.

Aid Station
We will have a fully stocked aid station throughout the event with water, electrolyte drinks, and food. Volunteers can prepare food upon request and assist runners in every reasonable way.

Race Course
The race route is a 400 meter all-weather track located at Central High School in Phoenix. The direction of travel will change every four hours. Portable restrooms will be available on the course, and showers will be available nearby.

Central High School track is located at:
4500 N 7th St
