Welcome to the Sunday Orinda Ride Series. We are an all-pace/all-skill training program. We invite everyone – from novice to speedy – to join us. This years series is a late start/shortened training season, which means we will increase mileage just a little faster in the beginning to get caught up with everyone else.

The 12th week of the Orinda Ride Series starts off with The Bear Loop, but with a twist. After climbing Mama Bear and a Baby Bear or two, we’ll take a left onto Happy Valley Road. You’ll be happy that we’re skipping Papa Bear, but don’t let the name “Happy Valley Road” fool you. It’s quite a climb before descending into Lafayette for a break. Then it’s on to another break in Danville. If you’re up for it, the route takes us out and up to the “Y Junction” on Mt. Diablo. It’s 10 miles out and 10 miles back. You can do as much as you want, as little as you want, or none of it at all. If you skip Mt. Diablo, your ride will be 52 miles. We’ll then head back from Danville via Lafayette, St. Mary’s Road, and Moraga on our way back to Orinda.

All skill levels are welcome! If any ride is too much, we will work with you on making sure you have alternatives to the entire route. You will have a great bike ride. That’s a win! And remember, safety is critical. We will be following all bicycling laws and regulations as well as COVID regulations.!

Reach out with any of your questions or concerns. You really can do this.
