A Halloween-weekend desert party where costumes, canyon glow, and fast loops collide
Overview
Javelina Jundred turns McDowell Mountain Regional Park into a neon desert carnival. Five buttery-runnable loops weave through saguaros and sandy washes with sunrise views and a sunset disco vibe that keeps spirits high when the miles get long. Costumes are encouraged, cheering is loud, and the energy at Jeadquarters feels like a festival with timing mats. Beyond the party, this is a serious race with a quick course profile, a deep field, and big goals. The 100 Mile is a 2026 Western States qualifier and a Golden Ticket race, so you’ll toe the line with contenders and community side by side.

The course starts and finishes at Four Peaks Staging Area, known as Javelina Jeadquarters. Expect smooth desert singletrack, firm jeep road, sandy washes, and short punchy climbs that reward consistent pacing. You’ll flow through Shallmo Wash, roll along the Pemberton Trail, pass granite boulders near Jackass Junction, then cruise gradual descents back toward Jeadquarters. Heat and exposure can be factors by day, and the night brings crisp, starry miles that favor steady runners with good lighting.

Requirements
This is a looped desert trail race with heat exposure by day and night running after sunset. Runners are responsible for personal hydration systems due to the event’s cupless policy and should plan lighting for evening and overnight hours.
Qualifying Races
No formal qualifying race is required to enter, but completing the 100 Mile in under 30 hours qualifies you for the 2026 Western States lottery, and top finishers earn Golden Tickets.
Mandatory Gear
Night running lights are strongly recommended for all runners expected to be on course after dusk. Carry sufficient hydration given the cupless policy and desert conditions. Reflective or high-visibility elements are recommended for night segments.
