$4,000 Podium Prize Purse!!

Welcome to the Southern California’s oldest 50k – this is the Bulldog Ultra’s 31st year in the beautiful, scenic, Santa Monica Mountains!!

Come run the challenging Bulldog Ultra course on Saturday, August 19th! Choose from the 25k Trail Run or the 50k Ultra.

The course offers epic views of untamed terrain and of the endless ocean from single track and fire roads weaving through the mountains. Do not be fooled by the beauty of the mountains and allure of the ocean. Temperatures can reach triple digits in the canyons and the climbs are steep and long. Runners will experience the full power of beauty and the beast.

Step up to the trails, tackle a 50k, crush your past times, or race for the prize purse.

The Bulldog Ultra 50k is the 3rd and final race of the Bulldog Challenge.
