About the Javelina Jundred
Javelina Jundred is Aravaipa Running's Halloween-weekend desert ultra at McDowell Mountain Regional Park. The 100-mile race combines competitive Western States stakes with a large, festival-style loop format.
Course
The 100-mile race uses rolling Sonoran Desert singletrack with repeated loops around the Pemberton Trail system. The format makes crew access and pacing predictable, but heat, sun, dust, and night miles still decide many races.
Race-day weather
Late October in the Phoenix area can still be hot in exposed afternoon sections, then cooler after sunset. Runners should plan for desert sun, dry air, and a long overnight push.
