California > Big Trees Trail Run Half Marathon, 10K, 30K & 50K
Oakland, CA  •  Sunday, May 6, 2012  •  Course Map

Towering redwood trees and breathtaking elevation climbs make the Big Trees Trail Run Half Marathon a truly memorable one, as runners will leave the hustle and bustle of city life behind as they trek through the trails of one of Northern California's most beautiful outdoor recreation spots in Redwood Regional Park.

Conveniently located about nine miles outside of Oakland adjacent to Joaquin Miller Park, this loop course takes runners on a journey they will not soon forget. The course climbs some 2,700 feet in overall elevation change over the course of the half marathon's 13.1 miles, with a highest elevation point of 1,400 feet, and is sure to be a favorite for trail runners of all experience levels.

Runners will begin the race in the Pinewood Picnic Area in Joaquin Miller Park. They take off on the Sunset Trail and hop on the Palos Colorado Trail soon thereafter. Runners climb in elevation along the Big Trees Trail for approximately a mile and will began to soak in views of nearby San Francisco once they reach the Sequoia-Bayview Trail at mile marker 1.3. The trail levels off a bit on the Castle Park Trail and Connector Trails before entering the Redwood Regional Park area. The first of three aid stations along the course is just before the mile 3 marker.

Once inside the park, runners head downhill on the East Ridge Trail and for nearly two miles on the French Trail, continuing their descent on the Mill and Stream Trails. The lowest elevation and the halfway point are located on the Bridle Trail deep within the park. Runners have a chance to rehydrate at the aid station right before hitting the Golden Spike Trail, whose small hills are nothing in comparison to the Toyon Trail, where an 800 foot climb over about a 1.5-mile stretch awaits. The climb continues on the West Ridge Trail and peaks at just past mile marker 10.

Runners will spend 2.5 miles along the West Ridge Trail as they head back towards the finish line. They will retrace their steps after they hit the aid station at mile marker 11.6. Winding their way through the Connector Trail and Castle Park Trails will remind runners that the finish line is near. The home stretch of the race descends along the Cinderella Trail, as runners make their way along the final mile on the familiar Sunset Trail in to the finish line.
