The Bay Ridge Endurance Runs have a new home in Cull Canyon Regional Park, which is about a 5-minute drive from the old start/finish at Lake Chabot but on foot, it’s a spectacular climb on the Bay Area Ridge Trail that many never see! You’ll be up and over in a few hours. Because of this new start/finish area, the Bay Ridge 100k now turns around at Steam Trains. The net elevation of the new course is 8,500 feet.

As in 2017, the Bay Ridge 100k has a start location that is off East Bay Regional Park property. 100k runners will park on the road in front of Cull Canyon and we’ll check you in there. We will start the race at 5am sharp at the entrance to Cull Canyon.

Bay Ridge 100k starts in front of Cull Canyon Regional Park. This is necessary so we can have a 5am start. The East Bay Regional Parks do not allow us onsite until after 5am. (Curfew is 10pm to 5am.) Bring your drop bags for the race and the finish and we will make sure they end up in the right spot. The first map shows this area around Cull Canyon. The second map shows a bigger area, with the course all the way to Bellhurst Lane and Chabot Staging Area.

Outbound: Start to Lake Chabot Staging Area. The race leaves Cull Canyon and runs around the Recreation Area in a counter-clockwise fashion, taking a left turn at Columbia Drive and then entering the trails shortly up the road on the left. This trail will take you around the recreation area, alonside the road and back to the Cull Canyon Parking lot on the Garin to Chabot Trail. You will pass through Cull Canyon on trail and then run through a tunnel that passes under Columbia Drive. Watch you heand! Then you’re off! on single track to the first aid station at Bellhurst Lane.

Bellhurst Lane will be a hydration- and gel-only aid station in the morning. At Bellhurst Lane Aid, runners will pass through stock gates into an area that contains horses, which graze there during the year. We will be feeding the horses in the morning to keep them out of your way. Still. be careful because they are animals and can be startled by your headlamps.

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 fire roads 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 down Redwood Road and after 1 mile will enter the trails again, on Proctor Trail, bearing right. Runners proceed to Ten Hills and turn right, then quickly bear right on Cameron Loop Trail, which runs by the streams and past the bridge that for many years was in the first part of the race. Cameron Loop becomes the East Shore Trail. Runners proceed 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.

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. This is the turn around point for the Dick Collins 50 mile, but not for you — keep going! Beautiful rolling trail and view await.
