The crossing

Mumbles ↔ Porthcawl: 22.6 km of shortest route, the shortest loop in the water around the island. No ratified crossing yet.

Distance is the shortest straight line between the start and finish coastal stretches, not the GPS track length: currents cause swimmers to cover much more distance.
