Greg LeMond has always been an active cyclist in the fight against doping. One of the gregarious who helped him win the 1990 Tour de France, Eric Boyer, and who was also manager of dopers like Cristian Moreni at Cofidis, Benjamin Thomas' team that has won stage 5 in the 2024 Giro d'Italia, believes that Jonas Vingegaard, Tadej Pogacar, Remco Evenepoel or Primoz Roglic are doing things that the dopers of the past like Lance Armstrong or Bjarne Riis didn't even do.
