How to get a place

There is no lottery and no qualifying race. Registration opens on UltraSignup on 1 January, and once a race fills there is a waitlist. Places come off it only when runners withdraw, and you have 72 hours to accept. In October 2026 the 100-mile waitlist had 560 names.

In 2026 the 100-mile cost $525, the 100K $375 and the 31K $195, plus tax and fees, and payment plans were available. There are no cash refunds or transfers. If you withdraw in writing at least 30 days before the race you get a 75% credit for another Aravaipa race, valid for a year.

Charity places through Wander Project waive the entry fee if you raise at least $4,000 for the 100-mile or $3,000 for the 100K.

• How race entry systems work

The course

Every loop starts and finishes at Javelina Jeadquarters and runs one way, mostly on the Pemberton Trail. You cross Shallmo Wash and climb gently about 600 feet towards the McDowell Mountains, through washes and boulders to Jackass Junction, the party aid station about halfway round, then descend gradually to Rattlesnake Ranch and back. The first loop is longer and returns on the Escondido Trail.

The trail is a mix of hard-packed granite, rocks and sand, with saguaro cactus all around and very little shade. Trekking poles are not allowed on the first two loops.

• Choose a race format

Aid, crew and pacers

Crews can only help at Javelina Jeadquarters, so they see you about every 20 miles, and crew tent spaces must be booked. You can leave one drop bag at Jeadquarters and one at Jackass Junction. The race is cupless, so carry your own cup, and take at least two bottles for the long gaps from loop 2.

Pacers can join the 100-mile after three loops or from sunset, whichever comes first, and must run full loops from Jeadquarters. One pacer at a time, and pacers cannot carry your kit.

• Plan your splits in the pace planner
• Crew and drop bags

Each loop passes three aid stations, Coyote Camp, Jackass Junction and Rattlesnake Ranch, before returning to Jeadquarters. The longest gaps are about 6.5 miles. The organiser publishes only the final-loop and finish cutoffs, by gun time for your wave. Source: official race website, checked 19 October 2026.

Records and results

The front of the race has become very fast. In 2025 Will Murray won in 12:10:12, with David Roche and Canyon Woodward also inside the old record, and Tara Dower won in 13:31:47. Finishers under 30 hours get a buckle, and a larger buckle for under 24 hours.

About six in ten 100-mile starters finish. The 100K records are Rajpaul Pannu's 7:15:53 and Anna Louden's 8:13:07, both from 2023.

Golden Tickets and qualifying

Javelina is a Western States Golden Ticket race. In 2026 the first two women and men earn entry to Western States 2027, and tickets roll down as far as fifth place. Any 100-mile finish under 30 hours counts as a Western States qualifier. It is not a Hardrock qualifier. Elite and age-group runners can be drug tested.

History

Phoenix ultrarunner Geri Kilgariff founded the race in 2003 as "the 100-mile party run", and Stephanie Ehret won it outright that first year. The first race raised $10,000 for the park. Jamil Coury became race director in 2008 and founded Aravaipa Running in 2009, which has organised the race ever since. Early races reversed direction each loop; the loops now run one way. The 2026 race is the 24th.

Running for good at Javelina

Aravaipa supports McDowell Mountain Regional Park each year through entry fees, camping permits and runners' contributions. In 2025 nine charity runners raised more than $37,000 through Wander Project, and a charity beer garden supports the Maricopa Trail + Park Foundation. Runners must pack out everything they bring. Volunteers get race credit, free camping and park entry.

Getting there and staying

The park is about 24 miles in a straight line from Phoenix Sky Harbor airport. Runners and crews park along the park road and take a shuttle, because there is no drop-off at Jeadquarters. Tent City, tent and car camping, and RV spaces are sold with registration. Live tracking is on the Aravaipa live site, and Mountain Outpost streams the race.
