A spokesman for the seven-times winner Lance Armstrong says he will make a Tour de France comeback next year.
The 37-year-old rider announced in September he was coming out of retirement for the 2009 season.
A cancer survivor, Armstrong won the Tour for a record seven consecutive years from 1999-2005.
The American retired following his 2005 victory and has since devoted himself to the fight against cancer.
It will be the first time Armstrong will ride the Tour and Giro d'Italia in the same year.
