Why not just bog off this bank holiday? It's not such a rude suggestion, because Monday August 28 sees the 21st annual world bog snorkelling championships in Powys, mid-Wales. Competitors, wearing flippers, mask and, of course, snorkel, have to complete two 60-metre lengths in a specially cut trench in the Waen Rhydd peat bog, without using any conventional swimming strokes.
Lured by the promise of an afternoon swallowing mud, people come from Australia, Europe and America to take part and clock up some remarkably fast times in four categories: world, women's, junior and local champions.
Llanwrtyd Wells, which hosts the championships, claims to be the smallest town in Britain, but it seems to have the biggest imagination for fund-raising events - it is also home to the Saturnalia Wobble, the man v horse marathon and Morris in the Forest. Perhaps it's something they put in the beer. More information: 01591 610 666, http:llanwrtyd-wells.powys.org.ukbog.
GO UNDER CANVAS
This may have been the summer that camping became cool, but savvy campers have long known the Camping and Caravanning Club (0845 1307631, www.campingandcaravanningclub.co.uk), gives access to a wealth of information and campsites across Britain. Members will celebrate the end of summer with the National Feast of Lanterns 2006 at the Cheshire Agricultural Showground, Tabley, from September 1-3. This event attracts up to 10,000 campers every year, with free outdoor games and an indoor marquee with disco and karaoke for children, and lots of other entertainment for families. The highlight of the weekend is a mardi gras and light display.
