INFERNAL 50k

Are you up for the ultimate challenge? New this year, the Infernal 50k is the ultimate endurance race, that will test the best trail climbers. Boasting more than 7,000 feet of climbing, the course takes you through stunningly beautiful coastal vegetation, climbing one of the steepest hills in Northern California (twice!), all while enjoying spectacular views of the Pacific Ocean and San Francisco County.

The course combines our 30k plus an additional loop of the half marathon, traversing every trail in San Pedro Valley County Park and heading to the summit of North Peak.

The course is tough, but you will be rewarded with jaw-dropping panoramas, an incredible sense of accomplishment, AND a catered all-you-can-eat lunch afterwards!
