Yes, all participants are required to wear a US DOT approved or CPSC standard helmet. No brain bucket? Then you can’t ride.

We’re hearty New Englanders and plan to roll rain, snow or shine….unless conditions are absolutely terrible, and then we’ll post cancellation/re-schedule notices.

We will miss you but, sorry, Registration fees are non-refundable.
