There are numerous pool-based freediving competitions held throughout the year in various locations around the world. There’s also abundant snorkeling to be had at beautiful reefs all across the globe.

And then there’s the World Bog Snorkeling Championships.

The event, held annually in August in a peat bog in Wales, requires the snorkelers to swim — on the surface — the length of a 65-yard/55-meter, water-filled trench and back, with the quickest time winning. Wetsuits are optional.

This year in a driving rain, Neil Rutter broke the previous men’s World Record with a time of 1 minute and 18.81 seconds. On the women’s side, Elinor MacCormac won with a time of 1 minute 48.46 seconds.
