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.

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.
