Tough Topanga

A grueling trail run in the Santa Monica Mountains Race #1 of the Bulldog Challenge Series!! Our most popular 10k trail run is back…with a brand new 15k distance and $2,500 Prize Purse!! This event historically sells out!! What used to be a no-holds barred run up a mountain in the 1970's, turned grassroots community running event, has become one of Los Angeles’ favorite trail races!! This classic trail run is one of the hardest 10k races in Southern California and offers a winner takes all cash prize, a "Downhill Mile" cash bonus, and the fastest "Local Legend" award!! We’re excited to introduce a gnarly “new” 15k race course dating back to the former Topanga Turkey Trot. The Hiker's Delight is non-timed, featuring an early start, full access to all aid stations and all the swag. Kids, get ready to race! The 1-kilometer course climbs along the Tough Topanga 10k course, but veers off and heads downhill on a super fun singletrack before the finish chute. All SoCalTrail events are CUPLESS.
