The Concord-Carlisle Time Trial, held rain or shine (with the exception of heavy thunderstorms), invites all cyclists to test their mettle. Open to both seasoned and novice riders with working bikes and helmets, this event offers a challenging yet welcoming atmosphere for enthusiasts. Participants must register exclusively through BikeReg by 4:30 PM on race day; no on-site registration is permitted. After the final registrations close, participants will receive an email detailing their start order based on date and time of sign-up. A mandatory riders' meeting at 6 PM in the designated lot ensures all rules are clear before the event begins. The course winds through picturesque Concord and Carlisle, following a USAC Non-competitive permit, meaning no licenses are required for participation. Detailed maps can be found online: [RideWithGPS](https://ridewithgps.com/routes/7811601) and [Strava Segment](https://www.strava.com/segments/627553). Weather conditions play a crucial role in the event's outcome, with cancellations communicated via email to all participants. If the race is called off due to adverse weather or road construction, Cyclists will receive a coupon code valid for future events. On race day, remember your start number and shout it out as you cross the finish line—a tradition that adds an exciting flair to proceedings. Results are promptly posted on both the Concord Bicycle Trailers (CBTT) Google group and NEBC’s Facebook page: [NEBC Facebook](https://www.facebook.com/northeastbicycle). Safety is paramount, so please behave respectfully towards local drivers as you navigate through the streets of Concord and Carlisle. Enjoy the scenic route while focusing on your performance.
