Olympic swimmer Keri-Anne Payne is supporting the British Heart Foundation's Bournemouth Pier to Pier Swim, a 1.

4 mile open water event taking place July 14. Payne said 'Heart disease is the UK's single biggest killer... Whilst research has come a long way, so many people still need help. This is why I'm lending my support to this year's BHF Bournemouth Pier to Pier Swim and encouraging people to sign up now for this fantastic sea swim challenge'.
