Lake Chabot Trail Marathon

Castro Valley, California

Course Details:

The half marathon course is a scenic, hilly loop, mainly on dirt fire roads.  The ridge-line views look down upon scenic Lake Chabot, surrounding grassy slopes, and eucalyptus groves.  Mt. Diablo and San Francisco Bay are visible along the route. There will not be any support or water stations, so we recommend bringing your own hydration. The 10K loop is what we like to call figure 8. You will have one little loop of the Ten Hills Trail then into a bigger loop on East Shore Trail along the beautiful lake.  The 5k (3.1 miles) course is an out and back that has gentle rolling hills and consists mostly of paved surfaces.
