About

Walnut Creek sits at the foot of Mount Diablo, ringed by protected hills, making it a favorite destination for athletes who want both city convenience and outdoor challenge. The Bay Area's mild Mediterranean climate and scenic setting make this an especially appealing spot, and it's easy to reach by BART or the major freeways. For those looking to test their endurance, the Diablo Summit Stomp offers a demanding route through the steep hills and valleys of Mount Diablo, which tops out at 3,849 feet in Mount Diablo State Park. Runners should come prepared for a tough, varied off-road challenge as they take on the mountain's shifting terrain.
