Trans Cambrian Way to Wessex Way any ideas/opinions on route.

Living at the end of the South Downs Way/Wessex Way I’m tempted to start at Dovey Junction ride the Trans Cambrian to Knighton then go to Weston Super Mare and continue on the Wessex Way, but I can’t seem to find any off road routes between the two, Offas Dyke Way seems to be mainly footpath so any ideas/opinions on route would be great.
Thanks.

Ive done the trans cambrian its a great few days out riding and camping.

Just bump this see if I get any more responses.

If you could find your way to Brecon the Taff Trail would take you down to Cardiff. I think there is a sustrans route then to Bristol.

sorry, to Ponty and then route 4 to Chepstow.
