Hi Richard,
Was having a play with the routes mode - specifically trying to route along EV1, which occasionally deviates from NCN route 4. From fishguard to Llannelli I was able to drag the route across from NCN4 to EV1 except for one section towards the end (see screenshot).
Cheers, Ant

This should be fixed now (c.t has slightly different handling for EuroVelo routes in the UK because they’re not generally signposted).
I’m not entirely convinced that NCN 4 and EV1 do differ in reality – I suspect both follow the new Pembrey railway path, with the old forest route retained as an off-road alternative. But I haven’t been there for a good few years!
