The start and finish will be at Castle Rock Park in Walnut Creek. For custom directions, click on "View Larger Map" and then click on "Get Directions".
Parking will be limited, so please carpool if at all possible! The main lot will be the Orachard Staging area, just before the park entrance. After that lot is full, overflow parking will be at North Gate High School. There is a short walk (about 1/4 mile) from the park entrance to the start/finish area.
