Matt – I haven’t done a route yet, but the Meidrim detour would add around 4 miles max, plus a bit of climbing. Rejoin the dual carriageway at Bancyfelin where the cycle path starts. I would then go through Johnstown and up Monument Hill into Carmarthen. We can avoid a bit more traffic/lights by going over the pedestrian bridge in Carmarthen and rejoining the main road near the railway station.
