What This Race Counts Toward:
Leona Divide 100K Description
Toe the line where the Pacific Crest Trail meets the high desert. Leona Divide 100K sends runners out from historic Lake Hughes across sun-baked ridgelines, oak-shaded canyons, and rolling fire roads on one of Southern California’s original ultras (racing since 1992). With roughly 10,000 feet of climbing across 62-plus rugged miles, it’s no easy 100K, but it’s a proven Western States qualifier that rewards grit with unforgettable high-desert views. Bomber course marking, generous aid stations, and a start-line-family-reunion vibe make this a bucket-list SoCal ultra for climbers and desert-lovers alike.
Always check the official race website for the most accurate and up-to-date race information and logistics.

Leona Divide 100K Additional Details:
Running the Leona Divide 100K feels like earning every mile of California’s high desert. The Pacific Crest Trail unfurls beneath your feet for hours: sandy singletrack giving way to sun-exposed fire road, then dipping into shaded canyon washes before climbing right back out again. Temperatures swing hard from a chilly pre-dawn start to a blazing afternoon and, for the slower half of the field, a cold nightfall finish, so runners learn to manage heat, wind, and darkness within the same race. The out-and-back structure means you’ll cross paths with friends and rivals mid-course, trading encouragement on the trail. Aid stations run cupless and community-powered, staffed by volunteers who treat every runner like family. It’s remote, exposed, and demanding, but finishing under the Lake Hughes night sky, WSER ticket in hand, is a reward that lingers long after the legs stop aching.
