Coverage of the training of Dafne Schippers, star sprinter on the Dutch track and field team, and other world athletes at IMG in Florida. 

Coach Rana Reider: “The 1080 Sprint is letting us push our bodies beyond what we would normally be able to do. We have women running over 11 meters per second and men running beyond world record phase. It’s doing things that we need to do to get their bodies used to running at yhe phase of world finalists and medalists.”
