Lance Armstrong has formally announced his retirement from cycling, more than a month after his last race.
The 39-year-old American, who made a comeback to the sport two years ago, said he was quitting for good to spend more time with his family and his charities.
Armstrong, who won a record seven Tour de France titles after surviving cancer, retired from cycling in 2005 but returned in 2009, finishing third in the Tour de France. His final race was at the Tour Down Under in Australia last month.
