Sydney: Over 500 competitors will take part in nude Olympics to be held in Australia during the weekend, Australian broadcaster ABC reported.
A range of physical competitions including tug of war, marathon and beach sprint will test participants` prowess and capabilities.
Less conventional events like the "best bum" competition, conga lines and egg throwing will also take place.
The event will be held at the Noosa National Park in Queensland - 130 km north of Brisbane. It was earlier postponed from its original schedule in March after catastrophic floods hit northeastern Australia.
An organiser said having fun was the aim of the tournament, rather than winning medals.
"There`s a whole bucket-load of stuff we do, but like I say, the emphasis is more on fun and camaraderie than out-and-out blood and guts glory," he said.
"As in most events the umpire`s decision is final, but when we get down to events like the men and women`s `best bum` or the `magnificent mums` we usually have to fight the judges off with a stick because everybody wants to get involved with presenting those medals."
