Javelina Jundred 100K
A hundred kilometres of Sonoran Desert singletrack: the 22.3-mile opening lap on the Shallmo, Pemberton and Escondido trails, then two of the 19.4-mile laps in alternating directions. It shares the start, the aid stations, the crowd and the finish arch with the hundred-mile race, and it takes in the hottest hours of the Arizona day without the compensation of a full night in the cooler dark.
For most of the field it is a one-day race that ends in the evening, which makes it the busiest finish of the weekend. This page belongs to the 2026 running of the 100K. On Livebib, family and crew see the runner moving along the real loop with lap splits, aid-station times and an arrival estimate for the next pass through Javelina Jeadquarters.
