Presented by
SoCalTrail’s premier ultra distance event - across the untouched Tehachapi’s on California's largest expanse of private land.
From the producers of the Bulldog Ultra and Pacifico Ultra comes SoCalTrail’s newest adventure!! Taking place entirely on Tejon Ranch, just 1-hour north of Los Angeles, 30 minutes from Bakersfield and conveniently off the 5 freeway, this is the only opportunity to explore these never-been-run trails preserved in time!!
No heatmaps. No FKT’s. No preview runs. No trespassing until race day!!
Discover the world-class diversity of southern California through canyons, along creeks, over mountains and across rolling sagebrush plains. The course runs entirely on fire roads, and may encounter abundant wildlife populations from Rocky Mountain elk, wild turkey, California mule deer, wild boar, black bear, bobcat, coyotes, raptors, to cattle roaming the working ranch.
SoCalUltraTrail at Tejon Ranch covers a full spectrum of pristine eco biomes home to ancient 300-year old oaks, springtime poppy and wildflower blooms, as well as distant Joshua Trees. This one-of-a-kind trail running adventure offers spectacular views from the Tehachapi Mountain range of Mount Pinos in the Angeles National Forest to the high desert and central valley expanses. The 50k and 100k are an ultrarunner’s dream taking on the iconic Grapevine switchbacks, self-powered on two feet, high above the 5 Freeway, while the 11k and 25k explore the local foothills.
Four Exciting Race Distances
Choose from the Tehachapi 100k, the Grapevine 50k, the Castac Lake 25k and the foothills 11k courses. There’s something for everyone at all levels!!
Overnight Camping & Hotels
Reserve your spot and arrive early for overnight camping opportunities for tents, vans and RV’s. Rooms at the Holiday Inn Express will be available with an official special event rate.
Finish Line Festival
Celebrate your finish with a hot cooked meals, beer garden (21+) and the sponsor hydration station. We’ve got everyone covered from pre-race coffee to late night munchies.
Spectators, Crew, Pacers
Reserve your pacer bibs for the climb up the Grapevine switchback and shuttle for the only aid station with crew and spectator parking access. Friends and family can be part of the adventure.
Rain, Shine or Snow
Grapevine Peak is one of the few, special locales in the Los Angeles area to occasionally receive snowfall, and just in case, we’re ready with heated aid stations, a finish festival party tent and warm, yummy food.
