Century Challenge [9/7/2025]
September 7 @ 6:30 AM - 4:00 PM
On Sunday, September 7th, we will host the “Century Challenge” fundraiser! This includes the metric century (100 kilometers) and imperial century (105-mile) routes you know and love! Please mark your calendar; our event registration will open after our June 8th Bike-A-Thon (get in your training miles now and register for the Bike-A-Thon!)
Event Details:
Challenge yourself to go further this fall when you ride in Bikes Not Bombs’ Century Challenge fundraiser ride! This event combines the long-distance Bike-A-Thon routes that you know and love with a laid-back atmosphere. This ride is largely self-supported, with hand-picked cafes, markets, and public restrooms marked along the route for you. All routes will depart from and return to Bikes Not Bombs in Jamaica Plain.
Exact routes for 2025 are pending, but you can see previous versions from 2024 on Ride With GPS: view the 105 mile route here and the 63 mile (100 kilometer) route here.
