The Bulldog Ultra

The Bulldog Ultra returns to Calabasas, California on Saturday, August 15th, 2026, presenting runners with a challenging course through the scenic Santa Monica Mountains. This long-standing event offers both a 50k and a 25k trail run along single-track paths and fire roads that weave through rugged terrain. On race morning at Malibu Creek State Park, participants can expect temperatures in the high eighties to low nineties with firm trails underfoot and UV levels reaching seven.
The Bulldog Ultra has been an annual tradition for thirty-four years, drawing hundreds of runners each year who come to test their endurance against the mountainous landscape. The race supports local businesses and minority-owned enterprises while raising awareness for trail conservation efforts in Southern California. Runners compete not only for personal bests but also for a significant prize purse totaling $3,500 across various categories.
The course winds through Malibu Creek State Park's trails, offering runners both breathtaking views of the ocean from high points and technical challenges on steep climbs within the canyons. Trail conditions are firm with some soft patches that may require careful footing during descent or ascent phases. Participants should prepare for potentially hot weather in August; UV levels will be at a high seven, making sun protection essential.

The race offers three challenging distances: a 75k Ultra Trail run, a 50k Ultra Trail event, and a more moderate but equally scenic 25k trail option. Each distance has its unique set of challenges, from the full day commitment required for the longest course to the shorter yet still intense trekking offered by the middle-distance race.

Bib pickup occurs on Friday from 4:00pm - 8:00pm at Malibu Creek State Park's parking lot. On Saturday morning, the parking lot opens for participants starting at 5:00am with registration beginning thirty minutes later. The start location is located at 1925 Las Virgenes Rd in Calabasas and runners should arrive early to familiarize themselves with the course layout.
