Cheese-rolling, caber-tossing, bowls, golf and cricket have little in common except for their origins in Britain's parks and village greens -- and the fact that they are excluded from Olympian glory.
On a typical rainy British summer afternoon members of the Finchley Bowls Club in north London emerge from the clubhouse, around five miles from the park where the Olympic Games will be held.
"We play in all weathers, including rain," says Ron Raymond, the club president. "We play if there's a cloudburst. We only stop if the grass is waterlogged, and that's because we don't want to damage the green."
Just down the road in this leafy enclave, which former premier Margaret Thatcher once represented in parliament, is the Finchley Cricket Club. Finchley Golf Club is a similar distance in the other direction.
Bowls, cricket and golf are just three of a wide array of non-Olympic sports that are popular here.
In London there are more than a dozen places for playing croquet -- the deceptively genteel but in reality viciously competitive game in which players knock balls through hoops with a mallet.
Then there's polo, which also involves hitting a ball with a mallet, except on horseback. The rules of the game and its original headquarters in Britain, where it was imported from India, were in Hurlingham, southwest London.
Across town from Hurlingham is Lord's, the spiritual home of cricket.
On a summer weekend in most English country villages, the type with thatched cottages and with handpumped ale in the pub, the thwack of leather on willow from a cricket match can be heard somewhere nearby.
Cricket last made a brief Olympic appearance 112 years ago -- and the closest it will get in 2012 is when Lord's hosts the Olympic archery competition.
Earlier this year the International Cricket Council, the sport's world governing body, said it was considering a bid to have cricket's shorter Twenty20 form return to the Olympics.
"We have never had a format that would lend itself to playing in the Olympics until Twenty20 came to the fore," ICC chief executive Haroon Lorgat said.
The ICC was officially recognised as a federation by the International Olympic Committee in 2010, meaning the ICC can bid to join the 2020 Games.
Bowls, meanwhile, is played at the Commonwealth Games, where Rob Weale of Wales and Natalie Melmore of England won the men's and women's singles titles respectively in New Delhi in 2010.
In Scotland, dozens of Highland Games meetings from May to August feature specialities such as caber tossing -- the throwing of a huge wooden log -- and tug of war.
Highland Games meetings share a similarity to the Olympics in that they are multi-sports events, although they also feature dancing and classes for playing the bagpipes.
"Highland Games have a long history and there's still a lot of interest all over the world," said Ian Grieve, secretary of the Scottish Highland Games association which represents 60 events in towns and villages across Scotland.
"I would like to think that holding the Olympic Games in Britain might have a positive impact for Highland Games though so far I haven't seen any evidence of it," he told AFP.
"We definitely get a positive spin off when the Open Golf is held in Scotland. Overall, I can't say we have seen a positive or negative effect."
English regions have their own local sports too, often big enough to run their own leagues. Quoits, which involves throwing hoops over posts sticking up from the ground, is especially popular in northeastern England.
Even more curious events include cheese rolling in Gloucestershire, southwest England, in which competitors chase a giant round of Double Gloucester cheese down a steep hill, risking injury.
The Wall Game, meanwhile, is played only at Prime Minister David Cameron's old boarding school, the elite Eton College.
And when it's raining, Britons can step up to the oche for a game of darts, play snooker or they take on the players from the pub's dominoes team.
Back in Finchley, none of the bowlers are bitter about their sport's non-Olympic status, adding that they are looking forward to the Games.
"I'll certainly be watching, selectively," says Ron Raymond. "I like basketball and then there's the gymnastics, especially the floor exercises. You have to admire the hours of work they put in to be able to do it so well."
