The August bank holiday weekend in Britain is often the opportunity for many to take part in unusual activities and this year lived up to expectations.
For mud-lovers in Wales, that meant a day spent at the World Bog Snorkelling Championships which celebrated its 40th anniversary in Llanwrtyd Wells.
Competitors raced through a peat bog using snorkels, with flippers permitted but conventional swimming strokes banned.
The event, which began as a tourism initiative, continues to attract participants and spectators to the rural Welsh town, offering an unusual test of endurance, technique and a right old laugh.
