Lance Armstrong to attend Tour

AUSTIN, Texas -- A spokesman for Lance Armstrong says the seven-time Tour de France champion plans to attend the final two days of this year's race.

Speaking Thursday, Armstrong spokesman Mark Higgins says Armstrong will attend the time trial in Grenoble on July 23 before going to Paris on the race's final day to host a party for Team RadioShack supporters.

Federal authorities are investigating whether Armstrong and his former U.S. Postal team participated in a systematic doping program. Armstrong, who won the Tour every year from 1999 to 2005, has steadfastly denied doping and has never failed a drug test.

He also plans to ride in part of the 39th annual RAGBRAI in Iowa, which runs July 24-30.
