Century Challenge: Ride Details
Join us for our first-ever Century Challenge on September 7th, 2025!
Register to Ride
Riders can register as individuals or as part of a team. Some of our biggest fundraisers have been part of a team, either with their friends, family members, or their co-workers! You can find more information about registration here. Please note that participation is limited to youth and adults aged 16 and up.
Fundraising
Riders can manage and view their fundraising efforts on the same site where they register here. You can find detailed instructions for how to set up your fundraising page, how to collect funds, how to meet your fundraising minimum, and more.
Routes
Both routes start and end at Bikes Not Bombs, located at 284 Amory St in Jamaica Plain, MA.
Choose from our two beautiful routes:
105 Mile Route: the Imperial Century
- Our 105 mile route takes riders on familiar roads in Boston, before encountering rolling hills in Weston, scenic farms in Lincoln, historic Concord, then heading further west to rural Acton and Littleton. Climbing in earnest, riders will be rewarded with beautiful views in Harvard, MA before winding their way back to Boston via Stow, Sudbury, Wayland, and Weston.
- 105.7 miles | +5,735 ft elevation gain
- Register for a 7:00am or 7:30am departure, each limited to 50 participants. Please arrive 30 minutes before your departure time for rider check-in and to grab some snacks before your ride!
63 Mile Route: the Metric Century
- Our 63 mile route covers much of the same scenic New England roads as the 105 mile, but with less climbing and more time to enjoy the ride! After reaching historic Concord center, you'll branch off of the 105 mile route down towards scenic conservation land in Lincoln and Sudbury.
- 63.7 miles · +3,120 ft elevation gain
- Register for a 8:00am or 8:30am departure, each limited to 50 participants. Please arrive 30 minutes before your departure time for rider check-in and to grab some snacks before your ride!
