It turned out he wasn't being entirely honest when he was winning all those races.
And the inevitable biopic of the extraordinary rise and fall of Lance Armstrong has begun filming, with this first picture of Ben Foster playing the cyclist just released.
The as-yet-untitled film is being directed by Stephen Frears, with Chris O’Dowd, Guillaume Canet and Jesse Plemons also starring. The movie is based on the epic David Walsh expose Seven Deadly Sins: My Pursuit Of Lance Armstrong, with John Hodge penning the script.
It promises to be a hell of a ride.
