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.
