The Nine Trails 35 Mile Endurance Run, scheduled for March 14, 2026, in Santa Barbara, California, offers an unparalleled challenge through some of the region's most stunning and formidable terrain. Known as an "absolute classic" in the California ultra-running scene, this race, established by local icon Patsy Dorsey in 1990, is celebrated for its "big climbs, big views, technical trails, and great people." Participants can tackle either the demanding 35-mile ultra or the rigorous 17-mile half, both starting from the Cater Water Treatment Plant. Typical race day conditions in mid-March often bring pleasant highs around 68F and lows around 50F, with only a 9% chance of precipitation, providing ideal weather for a mountain adventure.

The 35-mile course is an out-and-back journey covering most of the Santa Barbara front country trail system, leading from the Jesusita Trailhead to Romero Canyon Trailhead and back. Runners face a "shockingly difficult" route with over 10,500 feet of elevation gain and loss packed into its relatively short distance, prompting many experienced runners to liken it to a tough 50-miler. The terrain is a challenging mix of steep, rocky, and technical single track, dirt roads, and a few miles of pavement, featuring ten sustained climbs and notable sections like Inspiration Point, the rocky Tunnel Trail, and the infamous "Edison Catwalk," locally known as "the wall." While the course is minimally marked, requiring participants to use provided GPX digital mapping, the breathtaking vistas of the mountains and ocean provide constant visual rewards for the effort.

This event is strictly for experienced distance runners, demanding self-sufficiency due to long sections between the strategically placed aid stations at miles 9, 17, 26, and 31. The Nine Trails 35 Mile Endurance Run is more than just a race; it's an exhilarating and physically daunting experience known for fostering a strong sense of community among participants. Prepare for relentless forward progress and a profound sense of accomplishment at this legendary Santa Barbara event.
