In the ultimate sporting showdown, ten of the best teen athletes step outside of their own comfort zones and compete against each other in their rivals' sports. Each athlete sits out the competition in their own specialty sport, and instead mentors and coaches the others. Aided by world-renowned sports stars and Olympians, they are scored on skill, sportsmanship, and progress after each challenge. At the end of the series, one hardcore athlete will be crowned the All-Round Champion. It's an emotional and challenging journey of winning, losing, working as a team, and building relationships with peers. It's a competition that is as much a test of strength and skill as mental tenacity and preparedness. Who will come out on top?
