Edwin Moses began participating in track and field at an early age, but no one could have predicted where it would take him. Undersized in high school, he wasn't recruited to run track in college, and instead, went to Morehouse College on an academic scholarship to study physics. Morehouse didn't even have a track on campus, but Edwin kept training anyway using other facilities around Atlanta.

While still at Morehouse, everything would change for him in 1976 when he ran his first 400m hurdle race and discovered his signature event. Just 4 months later, he would win Olympic gold and set a world record in the event in Montreal. That victory began a run of dominance in the event that would last more than a decade and include 2 gold medals and a bronze medal at the Olympics, plus a victory streak of 122 straight races that lasted almost 10 years.

In 1988 while still competing, he helped create the sport's first process for out-of-competition drug testing. Now as a board member for the US Anti Doping Agency (USADA), he continues to advocate for clean sport with the goal to ensure a level playing field for all athletes.

In this episode, Chris and Kara interview Edwin to discuss it all. Edwin is undeniably the greatest 400m hurdler of all-time, but his impact off the track has perhaps been even more great. We can't thank him enough for his lifelong commitment to clean sport and for continuing to lead by example with action and not just words.
