Hereford on a hybrid (From Swansea)

[SuperHans123]

I reckon Banjo and Aravis are right, and that my initial thought about going via Abergavenny was more led by a fondness for a particular stretch of road than by smart route thinking. The route suggested by Banjo above makes use of the Golden Valley, which is a really nice section and very easy riding. Personally I'd have to iron out the section between Brecon and Talgarth a bit but if you want to cut down on main road sections then his route might be the best option.

Many thanks claud (and others mentioned)
I shall stitch together the two separate pieces of advice to make one route.
My plan now is to start cycling further over the next few months and to ride a chunk of the route beforehand.
I shall update this thread in due course with both progress and my charity link..cheers!
