Armstrong: Tour de France 'impossible to win without doping'

Disgraced cyclist Lance Armstrong has claimed it was impossible to win the Tour de France without using drugs during the time he doped his way to seven victories between 1999 and 2005.

On the eve of the 100th running of the world’s biggest cycling race, the American told French newspaper Le Monde that doping was so widespread at the time that only those who took drugs could win.
