It's hard. It's hilly. The road surfaces are dire. But you will get an outstandingly scenic route, with glorious views, pretty villages, traffic-free roads, and visit corners of the Cotswolds you barely knew existed.
Starting just outside Stroud, the route goes roughly northeast-southwest between Northleach and Dursley. Full details (routesheet, gpx, etc) are on the AUK website.
The start time has been set to allow you to get there easily by train (HQ is about 1km from Stroud station). But if you are coming by car, there is some parking at the HQ and plenty of free overflow parking nearby.
And the name? It's promoted by Dursley RC. Who else?
