World Bog Snorkelling Championships

Sports in Llanwrtyd Wells (Llanwrtyd)

The most famous of all Llanwrtyd's wacky events. Competitors are allowed wetsuits, snorkels and flippers to traverse a trench cut out of a peat bog, using no recognisable swimming stroke and surfacing only to navigate. Spin-off events include Mountain Bike Bog Snorkelling ('like trying to ride through treacle') and the Bog Snorkelling Triathlon, both held in July.
