Leona Divide

Leona Divide is run on the Pacific Crest Trail and the fire roads of the high-desert divide above Lake Hughes, at the northern edge of Los Angeles County. It has been held for more than 30 years, and Keira Henninger's KH Races has directed it since 2009. The weekend now offers four ultra distances from the Lake Hughes Community Center, on staggered starts: the 100 miles at 5:30 a.m., the 100K and 50 miles at 6:30 and the 50K at 7:00, with a 30K besides.

The 100-miler is 99.3 miles with 16,446 feet of climbing and a 33-hour limit, closing at 2:30 p.m. on Sunday, and the 100K and 50 miles share that close. The 2027 races are on April 17. Finishes in the 100 miles inside 33 hours and in the 100K inside 20 are Western States 100 qualifiers, and the top two men and women in the 50 miles earn Sterling Silver Tickets to the Angeles Crest 100.

All four ultras start and finish at the Lake Hughes Community Center on Elizabeth Lake Road and run on singletrack and fire road along the Pacific Crest Trail, marked with orange flagging. By the race's own course cards the 100 miles is 99.3 miles with 16,446 feet of climbing, the 100K 63.3 miles with 10,095 feet, the 50 miles 51.2 miles with 8,195 feet and the 50K 30.2 miles with 5,285 feet; the athlete guides' mileages are, in their own words, approximate. The 50 miles turns around at mile 42.5. Spunky Edison is a water-only stop that crews and pacers must hike into, and no crews are allowed at Bouquet Canyon or Lincoln Crest. At the San Fran aid station 100-mile pacers can join only on the second pass, at mile 68. Pacers need no bib or registration, the 50K allows no pacers or crews, and the race is cupless. A 100-miler cannot drop to a shorter distance after starting.

Entry is first-come on UltraSignup, with no lottery or qualifying race. For 2027 registration is open and closes on April 1 at 11:59 p.m. Pacific. The fees are $425 for the 100 miles, $250 for the 100K, $200 for the 50 miles and $185 for the 50K. The race publishes no field caps.
