In recent years, we have only run on the East Side of Lake Chabot, because of trails being made off limit to the race, and because of construction on West Shore. This year, West Shore is back. There is also a new segment on 10 Hill Trail near the start. Click and print the maps below.

Outbound: Start to Lake Chabot Staging Area. The race leaves Cull Canyon and runs around the Recreation Area in a clockwise fashion. Runners then jump onto the road briefly and enter the trails on the left, heading out on single track to the first aid station at Bellhurst Lane. This will be a water-only aid station in the morning. At Bellhurst Lane Aid, runners will enter a gated area that contains horses during the year. A course monitor will help with this gate on the way out. At the far end of the pasture is another gate. If a course monitor is not in position, runners will need to open and close the gate themselves. Runners continue through EBMUD land, along fireroads that offer a panoramic view of San Francisco Bay and Contra Costa County on a rarely-run section of the Bay Area Ridge Trail. The trail descends down sharply and rolls into Lake Chabot Staging Area.

Returning: Race returns along the same route to Bellhurst Lane. On return to the finish line, runners will pass through a tunnel (Watch your head!) and then bear a hard right out of the tunnel and up into the Festival Area.

Map 3: Anthony Chabot and Lake Chabot Regional Parks

On leaving Chabot Staging Area, runners will proceed on single track up and onto the Brandon Trail, turning left (Outbound). They will proceed down Brandon and then, strangely, along the entry to the Redwood Canyon Public Golf Course. Not to worry, you’ll soon be back on singletrack, turning right onto Proctor Trail. Runners proceed to Ten Hills and then down to the East Shore Trail, into the Chabot Marina, the traditional start/finish of the Dick Collins 50 mile. After aid, you’ll proceed out West Shore Trail and onto Grass Valley Aid, then down Jackson Grade to Brandon Trail and onto Bort Meadow. From Bort Meadow, you’ll proceed up and over MacDonald Grade to Big Bear.

You will return on this same route.

Map 4: Redwood Regional Park

From Big Bear, you’ll be in for a special treat, up rolling trails and then down onto the Stream Trail which winds up a watershed under tall redwoods. You’ll enter Skyline Gate Aid at the top of the valley. Now it’s time to turn around!
