Today is our day on the mountain. I've listed the traditional loop ride counterclockwise, but we may need to be flexible and substitute the (even steeper) west side up and back or something else depending on weather and road conditions. We'll finalize the night before at our cocktail hour. The loop has idyllic country roads for the first and last 15 miles, with a steep climb over Mt Fig in the middle and an uncomfortably steep descent on some poor pavement. There is a short section of unpaved road near the start of the big climb, and a slippery stream crossing to be very careful about. Lunch at Panino in Los Olivos, but that is very late in the ride so bring snacks. There is no reliable water available until lunch, so bring plenty.

Current membership in GPC is expected. A cheerful adventurous attitude is encouraged. Load the route into your navigation device or print your own cue sheet. Please pre-register if you would like the leader to keep some track of you.

Happy Valley Ride to the base of Mt Figueroa. And possibly to Los Olivos for Lunch

Starting from Plenty on Bell in Los Alamos, experience the incredible Cat Canyon climb without all of the extra mileage. Cross over Hwy 101, toward Alisos Canyon Road, do an incredibly bumpy frontage road, Ride the smooth and serene Alisos canyon, then follow Foxen Canyon north toward your destiny. Cat Canyon is the bumpiest road that I know of, topped off by grades occasionally over 10%! You'll love it! After this very hard one mile climb, you are treated to many miles of downhill, nearly making it all the way back to Los Alamos. Just before Los Alamos you need to cross highway 101, but you can do it in two parts, then easy cruising back to lunch at Plenty on Bell.

Helmets, cheerful attitude, etc. Be ready to ride at 9:45. It starts off easy.

GPC Tuesday is a Brisk paced loop through the Berkeley / Oakland Hills starting at the Reservoir @ Spruce / Grizzly Blvd. Ride is characterized as fast pace lines with close quarters pack riding skills required. The ride has approximately 6 re-groups along the route. (Slower riders do have limited time to arrive at re-group points, however, as wait times are limited to 4-5 minutes.) Route as follows: Grizzly Peak to Skyline pausing at Sibley (riders can join at approximately 6:05 here at top of Tunnel Rd), Skyline to Redwood Rd, turning left on Pinehurst Rd back to Skyline, returning to ride start or peeling off to return home individually. No E-Bikes.

This is the classic Tuesday night workout & skills ride, M-pace. Please read the ride details and route description at http://www.abriz.net/gpc/tues-ride.html. Bring your high energy, your high attention to safety, and your best bike handling and pack riding skills. Repeats every Tuesday through the last week of September. Preregistration is highly encouraged. No flashing lights please. No e-bikes please. Rain or bad AQI cancels. E-mail Mark if any questions.

Join us for a friendly TM paced paved ride. We meet at the plaza near the water fountain by Spruce and Grizzly Peak. This is an out and back to Chabot Space and Science Center. We'll head out along Grizzly Peak Blvd or Wildcat and up South Park. Then, take Skyline to the Science Center driveway where we'll climb the road to Chabot Space and Science Center. Brief regroups are at the top of South Park, Grizzly Peak at Skyline, and Chabot Science Center. Please carry enough food and water for the entire ride. Please pre-register by 3:30PM day of ride. Rain, bad AQI, or no riders pre-registering might cancel the ride. E-bikes are welcome on this ride.

The pace is TM (approx. 16mph solo effort on flats, up to 3w/kg climbing)

Note the later start time since we will be driving to get to the start. Accessed on our travel day between Solvang and Paso Robles, Pozo Loop offers up stunning scenery! There is good parking at the Community Park. Bring two full water bottles, as the water at the Ranger Station still says non potable. We will watch the temperatures. We generally eat at "The Porch" restaurant in town after the ride.

A cheerful adventurous attitude is encouraged. Strong navigation skills or riding with a buddy who knows the route can be very helpful. Please sign in online if you would like the leader to keep some track of you; there will not be a paper sign in sheet at the ride start. Two full water bottles and some nutrition makes good sense.

Miles and smiles, hills and thrills, lunches and lattes. This listing will be updated when the route and leader have been determined, usually by Monday evening. Meet at 10:00 am (usually) for this ride. Rain cancels. You can also join our web forum and check the forum archives for the current information.

This ride will start at El Cerrito Plaza BART. We will warm up riding the bike path 3 miles to the Alvarado Park entrance to Wildcat Canyon.

Bring warm layers and bright lights to see by on the way home. The majority of the dirt sections will be fire roads with two sections of singletrack at the end. We will have regular regroups and there will be an option to skip the singletrack sections at the end of the ride.

Meet for an early start with a prompt departure so that if you hurry, you could check out by 11 AM. People really will leave at 8 AM, and it will be cold!

I am leading the shorter version, but if you have time, you can extend the standard loop with an additional loop out to Cypress Mountain for a 40 mile ride. Peachy Canyon has one of the nicest, curviest downhills anywhere, and it seems like it never stops, until it makes you climb again and then have even more fun! If you plan on joining us, please let us know in advance, you should attend the happy hour / route planning meeting the night before, or check in with us, so that you are aware of any changes to the route, start time or start location. This is the day that many people will return home, so there often are changes. Bomb cyclones or atmospheric rivers may cancel. Helmets, cheerful attitude, etc.

We will ride to the Emeryville marina, then North on the Bay Trail for a clockwise loop to the Red Oak Victory Ship, Miller-Knox Park, bypass the Ferry Point Tunnel, & lunch @ Little Louie's. There will be an option to ride thru the tunnel.

Leisurely but challenging ride from the peninsula to the coast and back. Hopefully there will be clear skies, but it's always possible fog will take over on the coast. Several highlights: Sweeney Ridge, San Pedro Mountain (AKA Planet of the Apes), Gray Whale Cove Trail, Coastal Trail, Purisima Creek Trail. About a third of this ride is unpaved. It'll be more comfortable with wider tires (35 mm+) but it is entirely doable on a road bike if you're willing to deal with some bumpiness. Bring spare tube and flat-fixing tools. We'll be taking Caltrain, so be prepared with Clipper Card. Also bring enough water to last about 3 hours as there are very few potential water options after lunch.

Part 1: From San Bruno BART, start immediately climbing up Sneath Lane. This will gradually get steeper and eventually turn into Sneath Lane Trail (paved). We will continue until reaching the top of Sweeney Ridge. Loop around Sweeney Ridge and down Bacquiano Trail-this is really the only somewhat technical descent (narrow and windy dirt).

Part 2: Next challenge is San Pedro Mountain Road, formerly open to cars but maintenance lapsed and now it's a an eroded semi-maintained hiking/biking trail. There are a few rocky sections and a couple of sandy areas on the descent so be careful. Optional bathroom stop before looping out to Highway 1 on Gray Whale Cove Trail.

Part 3: Most of the next 10 miles are paved, a couple miles on Highway 1 before taking side roads and trails to Half Moon Bay. Lunch in Half Moon Bay-there are a few nearby options plus Starbucks. This is about the halfway point, but also the last real water and full bathroom until Woodside. If for whatever reason you're not feeling up to the rest of the ride, this is also the last real bail opportunity.

Part 4: From Half Moon Bay, we'll take the Coastal Trail to the end (very scenic, mostly unpaved route, secluded from traffic and right near the ocean), very briefly go onto Highway 1, and ultimately take Purisima Creek Road to Purisima Creek Trail, a fairly steep but well graded dirt climb. Then it's just descending into Woodside and Redwood City to Caltrain. If you want to go all the way to BART, you can take Cañada Road to Sawyer Camp Trail but that's on your own. Caltrain runs every half hour, and there is a discounted transfer between Caltrain and BART. If you end up driving to the start, San Bruno Caltrain is under a mile from San Bruno BART.

If no riders have signed up by 7 a.m. the morning of the ITT/GPC Pace Ride, it will be cancelled. If there is at least one rider signed up, it will go forward and riders can register online up until 9:50 a.m.

Individual Time Trial
Come test your fitness level and get in a great workout by riding the Bears Loop as a time trial. In the ITT, each person rides at his/her own pace (no drafting) to see how fast the Bears Loop can be completed. It’s a great format for pushing yourself to see how fast you can ride the loop.

Pace Group Ride
Ride the Bears Loop at your normal pace to use it to determine your GPC pace (https://www.grizz.org/rides/ratings.php). Or use this ride to train at a particular pace for an upcoming event.

The first rider is off at 10:01 and a rider a minute after that. For the GPC Pace ride, a pace group can start together, or each rider can rider on their own as the ITT riders do. (Regardless of the format, each rider is timed individually.)

Rider finishing times are usually shared in the ride report email to the club. While it is nice to see what times folks ride, reporting of rider times is optional. Also, the ITT is open to both members and non-members; no need to join as in the past.

Bring lights and warm layers.

GPC Tuesday is a Brisk paced loop through the Berkeley / Oakland Hills starting at the Reservoir @ Spruce / Grizzly Blvd. Ride is characterized as fast pace lines with close quarters pack riding skills required. The ride has approximately 6 re-groups along the route. (Slower riders do have limited time to arrive at re-group points, however, as wait times are limited to 4-5 minutes.) Route as follows: Grizzly Peak to Skyline pausing at Sibley (riders can join at approximately 6:05 here at top of Tunnel Rd), Skyline to Redwood Rd, turning left on Pinehurst Rd back to Skyline, returning to ride start or peeling off to return home individually. No E-Bikes.

This is the classic Tuesday night workout & skills ride, M-pace. Please read the ride details and route description at http://www.abriz.net/gpc/tues-ride.html. Bring your high energy, your high attention to safety, and your best bike handling and pack riding skills. Repeats every Tuesday through the last week of September. Preregistration is highly encouraged. No flashing lights please. No e-bikes please. Rain or bad AQI cancels. E-mail Mark if any questions.

Miles and smiles, hills and thrills, lunches and lattes. This listing will be updated when the route and leader have been determined, usually by Monday evening. Meet at 10:00 am (usually) for this ride. Rain cancels. You can also join our web forum and check the forum archives for the current information.

This ride will start at El Cerrito Plaza BART. We will warm up riding the bike path 3 miles to the Alvarado Park entrance to Wildcat Canyon. This will be a no drop ride good for riders new to gravel riding, training for the GPC Gravel Century, or just want to ride at a more chill pace. It is recommended to have 32mm or bigger tires. Bring warm layers and bright lights to see by on the way home. The majority of the dirt sections will be fire roads with two sections of singletrack at the end. We will have regular regroups and there will be an option to skip the singletrack sections at the end of the ride.

This weekly ride often tours through West Marin, but sometimes travels to Napa, Sonoma, or Livermore, depending on the season. We have frequent regroups and usually stop for a real lunch, if it is available on the route. This listing will be updated when the route and leader have been determined, usually by Monday evening. Status updates for weather cancellations will also be posted on the schedule.

There is sometimes a faster (more like M pace) group on this ride, but we all come back together at frequent regroups and lunch. Faster riders should feel free to push on after lunch. Just tell the leader first.

Please join us for this friendly Thursday evening TM ride. We’ll meet at North Berkeley BART (by the main BART entrance) at 5:20 pm, and we’ll be ready to roll at 5:30 pm sharp.

As the days get longer, we’ll add the (optional) out-and-back to Chabot Space and Science Center before heading down Shepherd Canyon. Bring lights and a jacket for the return trip.
