This has to be the most extreme way to complete the three peaks challenge - climbing the highest mountains in Wales, England and Scotland. Teams leave Barmouth on Saturday at high tide and sail to Caernarfon. Two of the team then run up Snowdon , on returning to Caernarfon, the crew sails to Whitehaven. The runners then leave the boat again for a 40 mile round trip to cycle and run to the top of Scarfell Pike. A final sailing leg takes the team to Fort William where the runners climb Ben Nevis. The race finishes when they return to Fort William, usually on Tuesday sometime. The start from Barmouth is preceded by a procession of the yachts from the harbour to the start line off shore with events, stalls and music on the quayside. There is also a 10k run across Barmouth bridge, along the estuary and back.
