Keira Henninger is excited to announce the first ever Santa Monica Mountains 100 mile. This out and back route will start in Point Mugu State Park on Friday May 13th, 2022 at 5am, and run all the way to the back country of Zuma Ridge / Zuma Beach, and back. The 100 mile course will combine the best parts of the Ray Miller 50 mile course, and the Sean O'Brien 100k course. With roughly 17k of ascent, and decent this will be one epic 100 mile race! Entrants will be able to apply for one of the very limited 150 spots on November 1st, 2021 at 6am. For those that applied for the lottery in 2020 you have first dibs on spots, and we will email you to invite you to register in November.
