El Jefe Hundred (Arizona, USA) 2027
Also known as: El Jefe 100
A 105.8-mile (170 km) point-to-point run through southern Arizona's Sonoran Desert, from Tiger Mine near Oracle to Superior. Almost all of it is remote singletrack among saguaro, palo verde and mesquite, with about 3,800 m of climbing. 2027 is the first edition, and it covers the same final 105.8 miles as the Arizona Monster 300 on the same weekend.
3,825 m of climbing over 170 km (22 m per km).
