Lance Armstrong
Armstrong brought cycling into the mainstream. He won seven Tour De France titles and also survived cancer as he became an American hero. But then everything went wrong after one of the biggest doping scandals ever. It emerged that he took PEDs throughout his career and forced his teammates to use them too.

World Cycling stripped his title and he lost millions in endorsements. But Armstrong showed the resilience of a honey badger. He refused to quit mainstream life and started a successful podcast. The former cyclist also had a cameo in the movie ‘Dodgeball.’ Armstrong is going from strength to strength despite his cheating (via Reuters).
