See all the gloriously muddy pictures from the 31st Bog Snorkelling Championship

Updated: 

When was the last time you dove head-first into a peat bog and swam as fast as you could? Not recently? Well then safe to say you weren't a competitor in this year's Bog Snorkelling Championship, held every August Bank Holiday in Wales.

Bog snorkelling enthusiasts headed to the Waen Rhydd peat bog near Llanwrtyd Wells yesterday for the unusual competition.

Stella McCartney was unfortunately not on hand to design any of the uniforms, but luckily contestants came prepared with their own suitably silly costumes. We're not sure if the man with the toilet on his back won the race, but he's a winner in our eyes.
