CRW Rides are open to members and limited guests. Guests may only attend two rides before joining.
All riders (both Members and Guests) must REGISTER

Register here:

If a rider has not pre-registered, that rider must do so online at the start of the ride. 

The online registration will include a liability waiver that all riders will need to review and accept. 

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.


Starting at the Station Ave parking lot in Groton, we'll bike on the Nashua River rail trail north to Peperell, Brookline, and Hollis.  There will be mix of paved roads, town maintained dirt roads, and park gravel roads.  Conditions will vary and a gravel bike is highly recommended.  Not techy but dirt road maintenance is an iffy thing.  Start at 10:00 and plan on about 5 hours plus whatever time is taken for lunch.  Hollis has a number of eateries and I'll stop at Buckley's for a snack.  I bike at a leisurely pace but feel free to bike at a pace that suits you. Oh, and by the way, there is some climbing involved.  Any questions, call, text, or email Gene at ho.eugene [at] or 617-610-1875
