LONDON (AP) — The rough-and-tumble world of open water is coming to the serenity of Hyde Park.

The women's 10-kilometer race will be held in the sprawling park located in the center of London, an unlikely setting for a sport that has dealt with its share of peril and tragedy.

Many of the swimmers will be thinking of American star Fran Crippen, who suffered a heat-related seizure and drowned during a 2010 event in the Middle East. But they won't have to worry about some of the hazards they face at other venues - like sharks in Hawaii or jellyfish in Australia.

The Olympic competition is being held at The Serpentine, a 28-acre recreational lake populated by plenty of ducks and fish the locals jokingly refer to as "British piranhas."
