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.

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

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.
