From the website (see link):

“Castles Bike Ride is all about having a good time and embracing cycling and friendship whilst raising funds for Macmillan Cancer Support. We believe that by coming together, we can achieve personal growth and success. Teamwork, motivation, support, and inspiration are the qualities that push our cycling community forward.

We host an annual Castles Bike Ride Charity event with 3 routes to choose from, so why not sign up today.”
