REGISTRATION OPEN

Deep in the Sonoran Desert, a lone jaguar once roamed the Sky Island wilderness. Known as El Jefe “The Boss” he became a symbol of the wild resilience of this landscape. The El Jefe Hundred is a tribute to that spirit.

The 105-mile point-to-point course runs almost entirely on remote singletrack through classic Sonoran Desert terrain — saguaro, palo verde, and mesquite stitching a scrubby green canopy across the landscape — all on National Forest Lands.
