There is a fantastic route out from Stratford that heads out to Broadway then across to Chipping Campden before heading around Mickleton and back to Stratford. Its one of my favourite training rides as it manages to take in a few nice hills.
I have started delivering a few bikes out to people staying in farms and cottages over past Mickleton and keep thinking to myself it must be a fantastic place to spend a week. Loads of cycling and perfectly placed to take in Stratford as well as the Cotwolds. If you are thinking of heading that way I would thoroughly recommend one place called Lowerfield Farm to anyone!
Dont forget to call and hire bikes before you set off though!!!!
