The American cyclist Lance Armstrong says he's been subjected to his 24th anti-doping control since August 2008, a month before he officially announced his comeback to professional road cycling.
The seven-times Tour de France winner is training in Nice ahead of this weekend's Milan-San Remo race, the opening one-day classic of the season and one of only five one-day 'monuments' on cycling's historic calendar.
The 37-year-old Armstrong says French anti-doping authorities took urine, blood and hair samples.
