if i may offer a slight change of route as this is my manor you slags .
cheltenham to winchcombe to toddington, turn right onto car manufacturers test road to Stow. go straight on to A436 and miss moreton, unless that's a tea stop.
the charlbury to burford road is best done that way............my own personal test track
I've refined the route a little:
Version2I had considered via Winchcombe and Cleeve Hill down to Cheltenham, but decided to try to keep it more flowing. The Charlbury section will do for the tight B road stuff - especially bearing in mind we may have up to 10 bikes in this convoy!
I'm also thinking about the guys doing quite a distance just to get to the start point, so don't want it to get too long.
I've kept Moreton, as the A44 from Chipping Norton to there is a lovely stretch, good surface, winding A road. The route will be done anti-clockwise, partly because I think that the Charlbury section wants people to be fresh - the road has several places where it could easily catch out a tired rider!
Ah bugger, ignore the little loop at Amesbury! Just used the town as a waypoint.
