Lance Armstrong's Team RadioShack has added the 2010 Tour of the Gila in southern New Mexico to its race calendar.

Team manager Johan Bruyneel announced on his blog that the annual stage race would allow some of the team's American riders to compete before the Tour of California in May. The Gila runs from April 28 to May 2.

Bruyneel didn't say which team members would race in New Mexico.

Armstrong and teammates Levi Leipheimer and Chris Horner were at last year's Tour of the Gila.

Last week, Armstrong pulled out of the Circuit de la Sarthe because of a stomach illness. He was competing in the four-day race to prepare for the Tour de France. He also plans to ride in the Tour of California before returning to Europe in June.
