Description

The 100K gravel route explores some of the greatest hits in our wonderful East Bay Regional parks. The first half of the day will take you through Sibley, Tilden and Wildcat before turning south to revisit Sibley en route to Chabot where the difficulty ramps up! The route covers about 63 miles with about 7,200 ft of elevation gain. This route will challenge you while helping sharpen your early season fitness and affording you the beauty of the East Bay.

Alternative Car-Free Start
