Golden Ticket Race

We are excited to announce that Javelina Jundred is a 2022 Western States 100 Mile Endurance Run Qualifier and Golden Ticket Race! The top two (2) female and top two (2) male finishers in each individual race will automatically qualify for entry into the 2022 Western States 100 event. In the case that the first, or second place participant is already in Western States (or decides to opt out), the automatic bid will slide to third place, fourth place, and subsequently down to fifth place as needed (no places below fifth will be accepted). Runners will receive their invitation via email and have two weeks from the qualifying race to complete the registration, including paying the entry fee. There are no deferments or transfers. Elite runners looking to compete in the 100 Mile Golden Ticket race, please email RD jubilee@aravaiparunning.com for consideration.

Jackass Night Trail

The 2021 event features an event within the event: Jackass Night Trail! A unique night race with TWO WAVES that grants participants a ticket to the party at Jackass Junction! Put your party pants or take them off to experience the course for one loop this Jalloween! Invite your friends, crew, family and every runner you know to the Disco the Desert October 30th!


The course is a five loop format with the start/finish area staged out of the Four Peaks Staging Area (Javelina Jeadquarters). Loop one will be 22.3 miles and include the Shallmo, Pemberton, and Escondido Trails. Loops 2-5 will be identical at 19.4 miles including parts of the Cinch, Scenic, Pemberton, and Shallmo Trails. Trails feature rolling single track through the Sonoran Desert. Run past giant Saguaro Cactus, granite boulders, and dry wash-beds as you tour the most popular trail of McDowell Mountain Regional Park. 100-kilometer runners will complete the first three full loops of the 100 Mile course.

Loops are run one way.

Each loop features a gentle 600-foot climb from the start/finish at Javelina Jeadquarters to the high point near the foothills of the McDowell Mountain range. The trail dips in and out of wash beds on the far side of the course before descending back to the start-finish. The trail is a mix of hard-packed granite, rocks, and sand.
