Christopher Morales Williams and the world record that wasnt
Canadian sprinter Christopher Morales Williams set a 400-metre world record earlier this year, but a technicality meant it wasn\u2019t ratified. Unfazed, the 19-year-old says it\u2019s motivated him to go and break that record all over again. He talks to guest host Mark Kelley about taking that determination to the Paris Olympics, and how he combats nerves and nausea before a big race.
