Greg LeMond is the only American man to win the Tour de France and remains one of the most influential riders in the sport's history. His 1989 Tour victory by 8 seconds — won on the final-day Champs-Élysées time trial using aero bars and a Scott aerodynamic position the peloton had dismissed — is the most famous margin in cycling. He pioneered modern training-by-power, was an early adopter of wind-tunnel work, and has spent the post-EPO decades as one of the sport's most credible voices on doping, governance, and what clean riders are physiologically capable of. Every conversation about pro cycling history runs through him.
