Re "Armstrong admits doping: 'I'm a flawed character'" (Tribune, Jan. 18):
As an amateur cyclist who considered being a professional in the '70s, I have followed Lance Armstrong's career.
Since the 1950s, cycling has been rife with doping, so much so that the likelihood of winning a major race clean has been almost nonexistent. As a physician and knowing the limits of physical endurance sports, I did not question the multiple allegations of Armstrong's doping. To win so many times, he had to dope.
