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.


CRW’s Winter Century Challenge is to ride one century per month in December, January, February, and March.

You pick the day. You pick the distance.
The imperial century is 100 miles.
The metric century is 100 kilometers.
The “Li Century” is 100 lis (a Li is an ancient Chinese unit, equal to ½ km).

Phillip is posting one imperial century in each month and invites others to join him on that day. However, winter is unpredictable--the roads may be unsafe, the children may be home for the holidays, the skiing in Vermont may be irresistible--so think of these century rides as placeholders. The date and route may change.


Date: Wednesday 12/29/21
Time: 7:00 AM (get there at 6:45 so we can roll at 7)
Start: Lexington Depot, 13 Depot Square, Lexington, MA
Route: Snowflake Century

Disclaimer: Phillip is planning to ride this route on this date but...Winter plans are fluid. If the roads aren’t safe, Phillip will ride a different day. If family commitments (holiday or skiing) change, Phillip will ride a different day.
