Prepare to challenge yourself at The Bulldog Ultra, Southern California's oldest 50K, returning on August 15, 2026, to the stunning yet formidable Santa Monica Mountains in Calabasas, CA. Choose your beast: a demanding 75K, the classic 50K, or a challenging 25K trail run. This historic event, often selling out, is renowned for its epic views of untamed canyons and the vast Pacific Ocean, traversing a mix of rugged single track and fire roads. However, don't let the breathtaking scenery distract you from the significant elevation gains and famously steep, long climbs. The 50K distance, for instance, boasts 5,784 feet of vertical gain over two challenging loops.

Runners consistently describe The Bulldog Ultra as a tough, beastly trail run, with some experienced ultra runners calling it one of the toughest 50K races they've tackled. Typical race day conditions in mid-August feature high temperatures around 97°F and lows near 61°F, with zero chance of precipitation, meaning runners should be prepared for intense heat, which can reach triple digits in the exposed canyons. To support you through this demanding course, fully stocked aid stations featuring Skratch Labs hydration are strategically placed, though runners are advised to carry ample fluids as distances between stations can be up to 5.6 hilly miles. Friendly and supportive volunteers are on hand to offer encouragement, water sprays, and ice-cold towels to help combat the heat.

The Bulldog Ultra offers more than just a race; it's a full experience. Finishers earn a custom medal and race tee, with free course photos to capture your triumph. The post-race festival at Malibu Creek State Park includes complimentary breakfast tacos, a 21+ beer garden, certified sports massages, and a lively atmosphere with a DJ. Competitors in the 50K can vie for a substantial $4,000 podium prize purse, and 50K winners even receive free entries for life, while the 25K offers a $500 course record bonus. As a proud cupless event, runners are encouraged to bring their own hydration vessels to help keep the beautiful Santa Monica Mountains pristine.
