Javelina Jundred

Javelina Jundred takes place October 31, 2026 at McDowell Mountain Regional Park, Four Peaks Staging Area (Javelina Jeadquarters). The event offers multiple race distances:

• 100 Mile
• 100 Kilometer
• Jackass 31K

The 100 Mile course is a five-loop format staged from the Four Peaks Staging Area. Loop one is 22.3 miles and follows the Shallmo, Pemberton, and Escondido Trails. Loops two through five are identical 19.4-mile loops incorporating parts of the Cinch, Scenic, Pemberton, and Shallmo Trails. Loops are run one way. 100-kilometer entrants complete the first three full loops of the 100 Mile course.

Trail terrain is rolling single track through the Sonoran Desert with Saguaro cactus, granite boulders, and dry wash beds. Surface conditions include hard-packed granite, rocks, and sand. Each loop includes a roughly 600-foot climb from the start area to a high point near the McDowell Mountain foothills, with descents and wash-bed sections on the far side of the course.

Camping and crew arrangements are organized at the event. Crew canopy reservations required a fee and were sold out for 2026. RV and short RV reservations were also sold out for 2026. Car camping is hosted in a designated lot with vehicle-contained overnight setups only; ground tents outside vehicles are not permitted.

The event serves as a Golden Ticket qualifier for the 2025 Western States 100 Mile Endurance Run with automatic bids awarded to top finishers and potential sliding of bids down to fifth place as specified. A separate Jackass Night Trail is offered as a single-loop night race with two waves and access to on-course festivities. Visit the organization's website for the most recent information.
