The only way is up on the Offas Dyke Marathon! Participants start at Prestatyn seafront and follow the National Trail Waymarkers out of the town and up into the hills - heading in a Southerly direction. Half Marathoners join in the fun at Rhuallt, and follow the same route as the full distance runners - finishing at over 500m above sea level at Foel Fenlli summit. Coach transport is provided from Bwlch Pen Barras back to Prestatyn for those that require it.
