On Saturday 28th April Mark Harold and his team will begin a demanding challenge cycling 750 miles in just 12 days to raise funds for both the Prostate Cancer Charity and the National Trust BMX project in Plymouth.
Richard Gould, Pete Rogers and Robert Sorrell are supporting Mark in his efforts and there are many others joining the boys for different legs of the journey.
The challenge is to visit 34 National Trust properties in 7 counties in the south west zig-zagging from the north to south coasts seven times starting at Hidcote Manor in Gloucestershire and finishing at Lizard Point!
You can find out more about these charities on the linked pages you need to visit to donate. We'd love you to split your donation between the two, but you might want to choose between them.
We have lots of fun with our cycling and enjoy having company so why don't you join us for one of our days, or for part of a day? We start on 28 April through to 9 May
