We're back at the Indoor Athletics Grand Prix in Glasgow on 20 February to talk to athletes preparing for this summer's Olympic Games in Rio. We hear from World 200m champion Dafne Schippers from the Netherlands and London 2012 bronze medallist in the men's 800m Timothy Kitum from Kenya. We also talk to Germany's 2012 Paralympic champion in the men's F44 long jump, Markus Rehm, who's set his sights on competing in the Olympics in Rio as well as the Paralympics. And we go back in time almost 100 years to find out about the 1920 Olympics in Antwerp.
