Come run the challenging and popular Bulldog Ultra on Saturday, August 24th, and choose one of two races - the 25k Trail Run or the 50k Ultra. This is the Bulldog Ultra's 28th year in the beautiful, scenic, Santa Monica Mountains.

The notorious Bulldog Trail was featured in Trail Runner Magazine as their favorite trail for July 2018! For those living in the Los Angeles area, it's easily accessible from both the Pacific Coast Highway and the 101 Freeway. Malibu Creek State Park also offers numerous trails in addition to the Bulldog Ultra race course to train on.

The Bulldog Ultra hosts several Course Preview Training Runs throughout the year. They are a great way to learn the course and meet others!

Official Preview Runs:

Join us at 6:45am by the huge Santa Monica Mountains sign on Las Virgenes and Mulholland for a course talk and group photo and a chance to stock up on Tailwind Nutrition before hitting the marked 15-mile course at 7:00am.
