Kara Goucher was the Silver medalist in the 2007 10,000m Track and Field World Championships. She went on to become a whistleblower that took down her former (now banned) coach Alberto Salazar. Kara is now an NBC commentator for this year's Track and Field World Championships.

Threshold catches up with her just before the 2022 Track and Field World Championships to reflect on her silver medal, endurance sport doping, nutrition issues, and a preview of the World Championships themselves.
