DIRECTIONS & PARKING

DIRECTIONS

The start and finish for all race distances will be at Castle Rock Recreation Area in Diablo Foothills in Walnut Creek (1700 Castle Rock Road, Walnut Creek). For custom directions, click on "View Larger Map" and then click on "Get Directions".

PARKING

Parking will be at the Orchard Staging Area, just before the park entrance.  There is a short walk (about 1/4 mile) from the park entrance to the start/finish area.  While we expect all participants to be able to fit in that lot, parking is limited, so if you can carpool (even if that means just parking a few miles away and only bringing one vehicle to the Orchard lot, that will help us.
