A good route. Quite a lot of turns, though, and a lot of these areas have slow internet. I´d recommend writing a lot of the turns down and keeping them in a pocket or taped to the tank.
If running clockwise, don´t make the same mistakes as me (I started from Banbury):
1) Stow on the Wold - if you continue along Sheep St, you need to go straight at the lights to follow this route (right-left)
1)I wasn´t expecting the double left turn in Tewkesbury from Church Street onto High street onto Mythe road. I had to stop and look at the route.
2)Weston Subedge - looking at the map on a phone, I wasn´t expecting to be turning left!
3) Chipping Camden - the left onto Cidermill lsne is easy to miss as the sign is currently not straight.
4)Some small sections of the B4035 have poor road surface - possibly subsidence - keep a bit in reserve unless you are familiar with the current state of the road.
Scenic route around the Cotswolds. Shipston to Banbury particularly good road.
