Lance Armstrong banned from running Chicago Marathon

CHICAGO -- The Lance Armstrong Foundation says the cyclist has been banned from running the Chicago Marathon.

Spokeswoman Katherine McLane said Friday that Armstrong will not be allowed to participate in the Oct. 7 race. Foundation President Doug Ulman said it was "frustrating and unfortunate" that Armstrong couldn't run, affecting the cancer charity's fundraising efforts.

The U.S. Anti-Doping Agency last month erased 14 years of Armstrong's competitive results and banned him for life, saying it had evidence that he took performance-enhancing drugs during a career that included seven consecutive Tour de France titles.

Armstrong, who retired last year, has denied doping.

Marathon officials said Armstrong didn't formally register for the race, but noted that USADA's ruling bars him from entering races sanctioned by USA Track & Field.
