Keri-Anne Payne wins Olympic open water test event in Rio
British double world champion Keri-Anne Payne won the 10km open water test event for the 2016 Rio Olympics.
Payne, the 10km open water world champion in 2009 and 2011, led a 15-strong field in the race, held at Copacabana Beach on Sunday.
Brazil's Ana Marcela Cunha was second, with Isabelle Harle of Germany third.
Payne, 27, was an Olympic silver medallist in the open water event at the 2008 Beijing Games, but finished fourth in London four years later.
