The online registration will also require all riders to review CRW’s Safety and COVID Guidelines and to agree to follow those guidelines on the ride.


The Bike Thursday Ride this week (7/15/21) will start in Carlisle.  We will be ambling through the hills and back roads of Carlisle, Concord, Acton and Chelmsford.  We will traverse the conveyance section of Chelmsford, streets named for all vehicles of transportation except maybe "buggy," then the bumpy section of Curve Street and on back to our starting point.  If that's not enough for you, bring your hiking boots and enjoy the trails of Carlisle.  Total mileage is just under 22 miles.  

The ride starts at 10:00 AM.  Registration is mandatory and will be limited to 24 participants plus 3 leaders.  We will be following the CRW riding rules.  Riders will be split into 2 or 3 groups depending on the number of riders and pace.  The overall pace of this ride will average between 10 - 13 mph and the groups will stay together.

Please check your calendar before signing up for the ride as you can not cancel through this site.  If you need to cancel please follow the instructions on your confirmation email or email Barbara Jacobs at nyder.jacobs [at]
