Bog snorkeling is all about getting back to nature — or better said, getting face deep into nature. Bog snorkelists swim two 60-yard laps using only flippers to power their way. The water is thick, brown, weedy and filled with all sorts of peat boggy things. Wales, where the the world championships take place every August, is not an especially warm country — racers are lucky if it breaks out of the 50s for the race.
