The small Welsh town of Llanwrtyd Wells – set among the Cambrian Mountains – has played host to the World Bog Snorkelling Championships for more than thirty years. This rather unusual and somewhat dirty competition, requires individuals to swim two lengths of a 55-metre water-filled trench – cut through the middle of the weed-infested Waen Rhydd peat bog – in the shortest possible time. Not your average sporting event, but nevertheless one that is fast growing in popularity. Bizarrely what started as a fundraiser in 1985 has grown into something of a global curiosity, with last year’s event seeing more than 150 hardy competitors pay to throw themselves into the filthy, murky waters. The rules stipulate that competitors must wear a snorkel and flippers and complete their swim without using any conventional swimming strokes. The fastest in the adies and mens categories at the 33rd championships on Sunday 26th August 2018 will be declared the winners.
