Bog snorkelling triathlon winner holds record for over 20 years. Begun in Wales as a barroom challenge, bog snorkelling is a race of snorkel-and-flipper-clad swimmers who must forgo normal swimming strokes to traverse their way through a 60-yard trench cut through a peat bog using only their flippers. The race evolved into a triathlon, which combines bog snorkelling with a three-mile foot race and a six-mile bike race through the mountains. In 1994, a man named Daniel Bent complete the course in just under two and one-half hours. His record for the triathlon has never been eclipsed.
