Distance Ultra marathon

About Sycamore Canyon 100k / 50K / Half

Sycamore Canyon Preserve consists of 2,272 acres of coastal sage scrub and chaparral-covered hills including the 325-acre Goodan Ranch, a mix of grassland, riparian, coastal sage, oak woodland and mixed chaparral. More than 10 miles of trails lead to grand vistas, abundant wildlife and interesting reminders of the history of human use of the area.

Dirty Feet Productions was founded in 2007 after creation of Orange County’s first ever 50/50 ultra marathon, The Twin Peaks 50/50. Dirty Feet was originally launched to fill the niche of ultra distance trail runs that were not offered at the time in Orange County. Dirty Feet’s mission is to provide dirt, fun, and quality at a reasonable cost. Dirty Feet’s annual Sycamore Canyon, ultra race provides just that. Held on the Goodan Ranch in Sycamore Canyon Preserve runners will enjoy a quality trail race.
