There are lots of lovely cycle routes in Wiltshire and plenty that run north-south and west-east across the Pewsey Vale.
Wiltshire Council promotes a route from Everleigh to Great Bedwyn with alternatives to shorten the route. They also have a route from Great Bedwyn to Marlborough.
Sustrans also maps routes across the country, with Route 45 being the main route around and across Wiltshire.
At a local level Pewsey Velo, run by Nick Gordon, has lots of advice on local routes for you and also provides help with repairs and servicing if the need arises whilst you are in the Pewsey Vale.
