Red Rock Sunset Rumble - Topanga, CA - September 19, 2026
The Red Rock Sunset Rumble is a trail event held at Red Rock Canyon Park in Topanga. The main running option is a 10k course that features roughly 1,360 feet of vertical gain and loss and runs mostly on fireroads with about a half mile of singletrack. The route passes through oak forests and chaparral, across red sandstone cliffs and a seasonal creek, with views toward the Backbone Trail, Saddle Peak, Santa Monica and the Pacific Ocean. Two major climbs shape the course and a steep downhill leads to the finish. Aid stations for the 10k serve Skratch Hydration and water at about miles 1.8 and 3.6.
A non timed Hiker's Delight route provides an alternative with less vertical at approximately 4.5 miles and about 1,075 feet of gain and loss; it has an aid station at mile 2.27. The event site includes a beer garden for those 21 and over, a vegan friendly taco breakfast, sports massage services, finish line announcers and music, free course photography, sponsor giveaways, same day results and professional medical support. All SoCalTrail races are cupless.
