This week's show has a distinct Olympics theme with the 2016 Games in Rio just two weeks away. We visit Ipanema Beach in Rio to find out about a popular sport played there which is now growing popularity elsewhere, called footvolley. Our series through the Games of the modern Olympic era continues as we reach the 2008 Games in Beijing and we meet the only athlete to beat the great Carl Lewis in an Olympic final, Joe DeLoach from the USA, who won the 200 metres in Seoul in 1988.
