At Waen Rhydd bog outside Llanwrtyd Wells in Mid Wales, a snorkel mask, flippers and a stretch of peat trench make an unlikely championship course. Competitors race through the water-filled channel in the World Bog Snorkelling Championships, a local event that Guinness World Records dates to 1985.

A course cut through the bog
The contest takes place at Waen Rhydd, on the edge of Llanwrtyd Wells in Powys. The route is a water-filled trench cut into the peat. Visit Wales describes the championship course as a 60-yard trench; racers cover two lengths, for a total of 120 yards.
The event’s organizer, Green Events, sets a distinctive kit list: a face mask, snorkel tube and flippers. Its published rule permits competitors to use a dog-paddle motion with their arms below the water. The course rewards rhythm and steady fin power as racers travel from one end of the peat channel to the other.

A small Welsh town with an unusual sports calendar
Llanwrtyd Wells has built a year-round calendar around playful outdoor challenges. Green Events also organizes events including a mountain-bike chariot race, a stone-skimming championship and the Man v Horse race. The bog snorkelling meet fits that local pattern: a simple idea turned into a gathering where participants and spectators share the day.
Costumes are part of the occasion. Visit Wales has described competitors in a pantomime-horse outfit and a participant carrying an ironing board while taking part in the bog race and an extreme-ironing challenge. The organizer’s 2023 recap recorded more than 150 participants and competitors who travelled from countries including Sweden, Denmark, Australia and South Africa.
The mix of sport and spectacle gives the championship its own character. A race through a peat bog asks for concentration, balance and a willingness to embrace the setting; the outfits give the sidelines a show of their own. Visitors can watch the event alongside food stalls, crafts and live music.
How the championship became a tradition
Guinness World Records lists the World Bog Snorkelling Championships as established in 1985. Its record page describes the event as a two-length race through a water-filled trench and notes that competitors arrive from across the world. The organizer continues to stage the championship at Waen Rhydd, giving the community’s oddball sporting invention a durable home.
That combination gives bog snorkelling its character. The course belongs to a particular landscape, the event brings visitors into a small town, and local organizers keep the playful tradition moving from one summer to the next.
