More than 800 people rode inflatable sex dolls down Vuoksa river rapids, 90 km from St Petersburg, at the ninth annual Bubble Baba Challenge 2011 - a bizarre but popular Russian race event. Anyone over 16, and of either sex, is allowed to take part in the competition. All they are required to do is swim in the complicated rapids of the Vuoksa river near St. Petersburg, on a plastic inflatable sex doll in a race that last little more than three minutes.
The word "baba" is Russian for "peasant woman," but is also a crude term with sexual connotations.
The unusual sporting event was dreamed up by mastermind and organizer Dmitry Bulawinov. He said the idea of floating down the river in the embraces of a rubber woman was conceived as a joke at a party where the men got drunk and the women didn't show up. While considering the possible uses for a rubber woman on a camping trip, someone suggested that a sex doll would make a handy flotation device. Thus the 'Bubble Baba Challenge' was born.
The event was first held in 2003, and has been taking place every year without fail.
