Heading out on this route: http://ridewithgps.com/routes/4047364 (or similar) at 10am on Sunday. Steady pace, probably finishing up somewhere between 16>18 av mph, with optional stop at Chartwell Barns for cake.
If anyone else fancies it, let me know...as if no takers I'll probably head out via Beddlestead rather than CSS.
Cheers,
Sam
