Open water champ Keri-Anne Payne backs swimming campaign

When it comes to courage and stamina, few Olympic events can rival the open water swim - a 10km free-for-all with no lane ropes to guide you.

Keri-Anne Payne will be going for gold for Team GB in London's Hyde Park in 2012 and she hopes her efforts will encourage others to give the sport a try.

BBC Sport's Matt Slater reports.
