A good B Road this one, pleasant scenary and an interesting selection of straight/corner combinations. Can be busy at peak times.
Staring and ending in Bristol this 254 mile route takes in some of the lesser ridden routes in and around the Brecon Beacons National Park. Aberagvenny Bus Station (not on this route but a short diversion) is home to the Oasis Cafe, a popular biker meeting point. The route at its most westerly point takes in the West End Cafe at Llandovery, another biker haunt and an ideal lunch location. This route was created using Tyre, a free motorcycle route planning tool by Jan Boersma. http://www.tyre.tk/
