The Rancho Cañada del Oro Trail Challenge in Morgan Hill, CA guides runners as they traverse single-track trails, fire roads, and climbs. If you’re looking for an easy and flat course, this may not be the right fit for you. But for those up to the challenge, the journey through the foothills of the Rancho Cañada del Oro Open Space Preserve offers exciting vistas of the Santa Cruz Mountains and Bay Area.
