Qualifier status per the 2026 lists
Founded in 2002 on the Pemberton Trail in McDowell Mountain Regional Park, Javelina Jundred runs five loops through open Sonoran Desert single-track — 7,900 feet of total gain, no shade, daytime temperatures that can push into the 90s. The Halloween timing is the identity: costumes are central, explicit music plays at Javelina Jeadquarters, and the event openly markets itself as R-rated. A Golden Ticket to Western States goes to the top finishers; in 2025, Will Murray and Tara Dower set course records of 12:10 and 13:31.
