paws

Description

The 102 mile course has roughly 8,000 feet of climbing.

The first 73 miles are identical to the metric century. From the start at Campolindo High School it climbs the east side of the Oakland-Berkeley hills via Pinehurst Road, then follows the ridge up and over Grizzly Peak and into Tilden Park to the rest stop at Island Picnic Area. It then drops down alongside San Pablo Reservoir and heads north to the edge of the Bay and the Carquinez Strait to the rest stop at Port Costa. From there it climbs McEwen Road for a run down into Franklin Canyon and Alhambra Valley, then over Pig Farm Hill and through the hills around Briones Reservoir to the rest stop at Briones Regional Park. Then it's back to Moraga and South Pinehurst over to the Firehouse rest stop on Redwood Road. After the rest stop, ride scenic Redwood Road through Chabot Park to the final rest stop at Proctor School, then turn around and return to the start for the post-ride meal.

Alternative Car-Free Start

If you use our optional car-free start at Island Picnic Area, you have a couple of options. Which is best depends on where you started and how you intend to ride home. If you live near Island, then we recommend you follow the standard 102 mile course to the Firehouse rest stop, then continue to Proctor and on to Campolindo for the barbeque. Enjoy your meal, then ride back to Island via the same course everyone else used in the morning. The turns are on your cue sheet. If you live near the South Loop of the course, then you may prefer to follow the Metric Century route to Campolindo and eat your meal first. Afterward, you can continue to the south and leave the course wherever it suits you to get home. Remember, the car-free start is intended for local riders who are familiar with the area and the common cycling roads.

Tricky Bits

At mile 3.1 there is a bridge with one-way alternating traffic controlled by a signal. Use caution and wait for the green.

At mile 4.4 all riders turn right onto Pinehurst Road. The yellow markings on the road will say GPC AM with an arrow to the right. Do not be confused by the marks that say GPC PM, which point to the left. Those are for when you return to this point in the afternoon.

At mile 41.7 in Crockett turn left onto Rolph Ave. In past years the route went straight, so if you are a returning rider you could easily miss the improved route.

At mile 44.6 turn left on Canyon Lake Road and go downhill to the rest stop at Port Costa. It is easy to miss because you will be descending.

At mile 61.9 turn left into Briones Park to go to the rest stop. It is on a fast descent, so easy to miss.

At mile 72.9 turn right onto St. Andrews Drive. The yellow markings on the road will say GPC 102 with a right arrow. At this point, the Metric Century riders will continue straight, so there will be additional road markings for that route. Be carefull not to follow riders who are not on your route.

At mile 73.8 you will encounter the same traffic controlled bridge you crossed at mile 3.1.

At mile 75.1 turn left onto South Pinehurst Road. The yellow markings on the road will say GPC PM with an arrow to the left. You may remember you turned right here in the morning.

At mile 78, after visiting the Firehouse rest stop, turn left on Redwood Road as you leave the rest stop (downhill, back the way you came).

At Mile 98.8 you will encounter the traffic controlled bridge for the third time.
