The Sirs cycle group continues to have a great time getting together for some vigorous adventures and old standby local rides. We have 18 active members in the group that join in the fun and fellowship on our weekly rides. We have grown in numbers as new younger Sir members come in with physical exercising high on their priority list. Most of our rides have been in the 20 to 50 mile range, and our easy rider members still get out for shorter rides.

For those that would like to join us, we plan easy rides on Thursdays and challenging rides on Mondays.

If you are interested in more information about the cycle group please contact co-leaders Bill Corbett or Frank O'Neill (contact information is available in our membership directory).

We resumed riding on Monday June 1st.  Then canceled due to civil unrest.  We did ride on Thursday the 4th and Monday the 8th.  We had 10 riders on Thursday and 8 on Monday.  Moving forward, we will continue to schedule rides every Monday and Thursday.  Challenging rides on Monday and easy rides on Thursday.
We had 4 organized rides during March.  Then on Monday the 16th, we finally had our first rainout of the year!  We were kind of happy, because we really need the water.  Well, as it turned out, our last ride was the prior Thursday.  We all know the rest of the story.  We did have some good turnouts, we averaged 11 riders on our 4 rides.  Went a total of 98 miles.
To all SIRs, wish you good health and be safe!!  Hope to see you soon.
The weather was an unexpected dry month.  So, no rainouts in February!!

Members are able to select from an average of about three rides a week that vary in difficulty. Email messages for upcoming rides are usually sent out several days in advance.


Our rides include easy rides which last for about an hour or so and are on mostly level terrain, usually stopping for refreshments at a local coffee shop, and covering about ten miles.

Our more moderate rides last around two hours and include some short hill work often right here in the San Ramon Valley and will cover about 15-20 miles.

Our moderate/difficult rides are from two to three hours with a bit more hill work and usually covering about 25-30 miles or so.

Our difficult rides are usually from 30-50 miles lasting about four to five hours with more challenging hill work and often include a stop for lunch.

Most of our members have road bikes. We all wear helmets, carry cell phones and liquids, observe traffic laws, and are courteous to walkers, joggers, automobiles, and other cyclists. The pace for each ride is set at a speed that allows all cyclist to stay together.



One of the challenging organized rides that our group has participated in pretty regularly is the Tour de Peninsula. This ride which starts at Coyote Point Park south of SFO offers four routes: 20 miles, 31 miles, 56 miles and the metric century 63 miles.


Another challenging organized ride is the locally sponsored Mount Diablo Challenge which is usually held in October. Traditionally, the Mount Diablo Challenge is an 11.2 mile timed bike ride, starting at Athenian School in Danville and climbing up Southgate Road 3,249 feet to the summit of Mount Diablo. 1,000 cycling enthusiasts compete and prizes are awarded for several categories in a ceremony at the summit with food.
