Day 1: Holyhead → Rhosneigr
43.9 km / 27.3 mi · 479m↑ · 479m↓ · 7h 6m
A fast opening day covering the entire western coast. From Holyhead the route blasts through the dramatic RSPB South Stack reserve and around Holy Island's rugged coastline to Trearddur Bay. After crossing Four Mile Bridge to mainland Anglesey, the terrain flattens for a fast section through dunes and past RAF Valley to Rhosneigr. The mix of cliff paths, sandy beaches and quiet lanes keeps the running varied.
