Entrants must negotiate two lengths of a 60-yard trench through the peat bog in the quickest possible time without using any conventional swimming strokes.

The participants were dressed in superhero outfits. One man even had a toilet strapped to his back, a woman was dressed as a mermaid and another donned a lifeguard outfit to a crocodile strapped to his back. (All pictured)
