The 77 Percent — What does it take to become a champion?

What makes a champion? This week, The 77 Percent explores what it takes to become a world beater. We'll investigate the role of mentors in achieving excellence, and whether nutrition plays a part. We'll also introduce a new star in the eSports movement and travel to Togo to meet those who are running to save the planet. Finally, we'll sit down with a marathon G.O.A.T for some wisdom.
