Ahead of the Olympic Games in Rio we visit a project in the city that uses futsal to offer hope and a safe environment to young people living in what can sometimes be violent communities. We hear from South Africa's 400 metres World Champion Wayde van Niekerk who last week completed a remarkable treble of running the 100 metres in under 10 seconds, the 200m in under 20 seconds and the 400m in under 44 seconds. And we continue our series on the Games of the modern Olympic era as we revisit the 1928 Games in Amsterdam.
