Race organizers say runners need to be ready to “get dirty on Diablo” when they climb the sometimes steep hills and valleys at the Mount Diablo Trail Adventure & Summit Run, which includes a 13.1-mile half marathon, a 10K run and a 5K run that takes runners up the slopes of Mount Diablo, which sits at an elevation of about 3,849 feet above sea level in the middle of California’s Mount Diablo State Park.
One of the San Francisco Bay area’s most beautiful parks, Mount Diablo is known for its distinctive rock formations and is filled with miles of trails for hiking, walking, horseback riding and camping. The race is billed also as the “Save Mount Diablo” race, to raise funds to help protect the environment here on the mountain and in the surrounding park area.
The half marathon, full marathon and 10K races share the same starting line at the Castle Rock Park area of the park, just off Castle Rock Road in the northwest corner of the park. From there, the course follows a course that takes runners southward and westward along the fire roads that lead through mountainous terrain, with plenty of water crossings and muddy and rocky areas, all the way up the slopes of Mount Diablo. The course follows an out-and-back loop route, and returns back to the starting line for the finish along Pine Ridge and through Pine Canyon.
While there will be three aid stations set up along the course, runners are encouraged to carry their own water bottle or hydration pack, as this is a trail race and they will need to stay hydrated. Walkers for the half marathon or those planning to take longer than 3.5 hours will start at 7:30 AM, followed by the half marathon start at 8:00 AM.
