Jan Ulrich, the 1997 Tour de France cycling champion, has admitted to doping during his professional career.
Ulrich is the winner of the 2000 Olympic Games, two-time world champion, winner of the Vuelta and the Tour de France.
"Yes, I doped," Ulrich said during the presentation of a documentary series about himself, noting also that he could not confess to his violations for many years.
Recently, Jamaica's Ronald Levy, a bronze medalist at the 2020 Olympic Games, failed a doping test.
