The London 10km Marathon Swimming International is coming up on August 13th. The tactics that the male and female Olympic 10K swimmers use a year from now may – or may not – be on display. What is going through the heads of these athletes as they give the course in the Serpentine a test? The race will be interesting for everyone involved – the top athletes, organizers, media and fans. And many British eyes will be on home country hero, Keri-Anne Payne.
