Mt Umunhum Ultras

Sat June 10 @ 5:00 am - 5:00 pm


It is with great excitement that we present the trail running community with an exclusive trail racing event – the Mt. Umunhum Ultras!

Join us for over 15,000 feet of elevation gain on a 52 Mile, or 50K adventure that will take you through mystical oak forests, endless meadows, and steep climbs in the Santa Clara Valley, Sierra Azul Open Space Preserve, and the Santa Cruz Mountains. Be careful what you wish for, these Ultra Races are not for the faint of heart.

For those wishing for a piece of the epic adventure without all the pain, we also offer our more traditional shorter distances, along with a friendlier later-morning start. Whichever trail run you choose, Mt. Umunhum won’t disappoint and we look forward to seeing you out on the trails.
