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. Loops weave through saguaros and sandy washes, with a sunset disco vibe that keeps spirits high when the miles get long. Costumes are encouraged and the energy at Jeadquarters feels like a festival with timing mats — but it's also a serious race with a deep field and big goals. Three distances: 100 Mile, 100K, and the evening-start 31K (Javelina Jackass Night).
Land Acknowledgement
Javelina Jundred takes place on the ancestral lands of the Akimel O'odham and Yavapai peoples in the Sonoran Desert.
