Arizona's costumed 100-mile party run and WSER Golden Ticket race
Other trail races within 78 miles
The flagship Javelina Jundred 100 Mile covers one 22-mile opening loop on the Escondido Trail, followed by four 19-mile loops on the Pemberton, Shallmo, and Cinch trails — a five-loop format that cycles runners through the party at Javelina Jeadquarters all night long. The course is fast by desert 100-mile standards, with just over 6,000 feet of gain on rolling Sonoran singletrack, making it popular for debut hundreds and PR attempts alike. The race is a WSER Golden Ticket event — the top 2 men and women earn automatic entry to the following spring's Western States 100 — and all finishers under 30 hours earn a 2027 WSER lottery qualifier. Runners start in two waves: Wave 1 at 6:00 AM for Golden Ticket contenders and sub-24 hopefuls, and Wave 2 at 6:30 AM. Cutoffs run on each wave's own gun time, so both waves get the full 30 hours. Trekking poles are not allowed on the first two loops.
