Prepare for an unforgettable challenge at the Tough Topanga, returning on June 20, 2026, to the stunning Topanga State Park in Topanga, CA. This iconic event, known as one of Southern California's hardest 10K races, also offers a new, gnarly 15K course following the historic SoCalTrail Turkey Trot route, along with a Hiker's Delight and a Jr 1k for younger runners. Runners will navigate rugged, steep trails that wind through oak forests, chaparral wildflowers, and dramatic sandstone cliffs, offering breathtaking valley vistas and expansive views of the San Gabriel mountains and the Pacific Ocean. Typical race day conditions in June see comfortable lows around 58F and highs around 91F, with virtually no chance of rain.

The courses, starting and finishing at Trippet Ranch, feature significant climbs broken into sections, interspersed with welcomed descents that challenge every runner. The 10K route includes approximately 1,100 feet of climbing, taking participants up to landmarks like Eagle Rock and past Hub Junction. The new 15K extends the adventure with an additional four miles of exciting singletrack. Both distances culminate in the thrilling "Downhill Mile" challenge, offering a cash bonus for the fastest splits. This fully-supported race, lauded by runners for its "beautifully brutal" course, provides expertly marked trails and aid stations staffed by local run clubs, complete with professional medical support.

Beyond the challenging terrain, the Tough Topanga experience is a vibrant community celebration. Participants receive handcrafted medals and race tees, and can look forward to a complimentary post-race breakfast, hot cocoa, coffee, and a beer garden for those 21+. Free race day photos and post-race sports massages by Vision For Enrichment ensure a memorable finish. The event proudly supports LA Fire Station 69, with a portion of the proceeds dedicated to keeping the Santa Monica Mountains safe. As part of the prestigious Bulldog Challenge Series, the Tough Topanga is more than a race; it's a test of grit amidst unparalleled natural beauty, attracting a diverse range of competitors and historically selling out.
