Watch the spectacle as 150 swimmers swim and walk between Scilly's main islands in just one day.
Starting at sunrise from Bar on St Mary's north side the swiimmers head first to St Martin's arriving at Higher Town Quay. They then walk the length of the island to Lower Town Quay. Here they set off for Tresco, to Old Grimsby Quay passing Tean and St Helen's.
After walking across the backbone of Tresco to New Grimsby, they head off once again for the shortest of the swims to Bryher and then on to Samson. From Samson, comes the penultimate swim and arguably one of the toughest - through the deep channel to St Agnes.
And then the longest swim of all to wrap up the challenge - from St Agnes to Porthcressa Beach back on St. Mary's.
