The Discovery Vitality Summit, held from 15-17 August this year, featured a number of keynote speakers, both local and international. One of the main draw cards was Tyler Hamilton, former professional cyclist and teammate of Lance Armstrong. In his talk, Tyler opened up about his journey and the choices he made that led him to become a cycling champion and a user of doping substances. He also fielded questions from the audience about his experience. The footage is an edited version of his talk.
