X is a sport started in 1976 in Llanwrtyd Wells, Wales, United Kingdom, as a result of an over the bar conversation between Gordon Green and a few regulars. It consists of competitors completing two consecutive lengths of 60 yards(55 meters) water filled trench cut through a peat bog, in the shortest time possible. Participants must wear snorkels and flippers, and complete the length without using any conventional swimming strokes, relying on flipper power only. World X Championship, first held in 1985, take place at a dense peat bog in Wales, UK, and attracts more than 200 entrants every year. The current world record is 1 minute 30.66 seconds.
