Pre-registration
It wasn’t raining in sf but it is raining in mill valley
My actual birthday is 9/5, but 9/2 is the date celebrated in my family from ages 5 to ~16, so it's a good day for my Birthday Ride. We are doing Mt Tam Direct so most of us will not regard the summit as optional--the ride is mostly out and back so if you don't want to go to the summit, come along anyway. Some will find this ride too short. Rita will park near the Richmond Bridge, and ride to the ride start.
We'll ride from Mill Valley up to a regroup at Boot Jack and then on to Ridgecrest Blvd and up to the Summit. Bring enough snacks to power you to the top. Lunch will be at the Junction Beer Garden/Pizza Hacker (226 Shoreline Hwy) at mile ~26.
Two variations on the route: Chris and I like to descend Hwy 1, but many people prefer to descend through Mill Valley
https://ridewithgps.com/routes/56722088 Mill Valley descent
https://ridewithgps.com/routes/56722357 Highway 1 descent
PLEASE PREREGISTER--early if you can
It's too early for the weather forecast. Hoping the predicted rain on Mon and Tues will exit the scene

GPC Route: Heather Farm, Morgan Territory, Diablo Junction

Pre-registration
This is a scenic loop ride with two big climbs: Morgan Territory and Diablo Junction. Meet at Heather Farm by the baseball fields near water and restrooms. Heather Farm is close to Pleasant Hill BART and there's lots of free parking. Route can modified to avoid the second climb to the Junction by riding along Danville Blvd. We can figure out who is up for the second climb while having lunch at Tassajara Crossing.
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.

GPC Route: Bears Loop
Start Location: Orinda - San Pablo Dam Rd and Bear Creek Rd
Mandatory pre-registration
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.

It wasn’t raining in sf but it is raining in mill valley
My actual birthday is 9/5, but 9/2 is the date celebrated in my family from ages 5 to ~16, so it's a good day for my Birthday Ride. We are doing Mt Tam Direct so most of us will not regard the summit as optional--the ride is mostly out and back so if you don't want to go to the summit, come along anyway. Some will find this ride too short. Rita will park near the Richmond Bridge, and ride to the ride start.
We'll ride from Mill Valley up to a regroup at Boot Jack and then on to Ridgecrest Blvd and up to the Summit. Bring enough snacks to power you to the top. Lunch will be at the Junction Beer Garden/Pizza Hacker (226 Shoreline Hwy) at mile ~26.
Two variations on the route: Chris and I like to descend Hwy 1, but many people prefer to descend through Mill Valley

Bears Loop
Start Location:
Orinda - San Pablo Dam Rd and Bear Creek Rd
Mandatory pre-registration
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.

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.

Start Location:
Emeryville - Opposite IKEA
Join us for the Treasure Island lap, starting at the Bay Bridge base of the Alex Zuckermann bike path. This ride features shorter regroups, a faster T to Moderate pace - particularly on the bridge ascent and descent - and sparkling city skylines. Expect one short, steep descent and a challenging half-mile climb off the island (7-10% grade average with some brief spots at over 15%). Daylight permitting, expect short additional climbs to the signal tower and from the base of YBI. Ride typically ends near IKEA before 7pm. Many participants and the group leaders head back north towards Berkeley and beyond as a group at a conversational pace
