Lance Armstrong banned from marathons for doping

(WSCR) If Lance Armstrong wants to exchange his seven Tour de France titles for seven Chicago Marathon titles, he won't be able to do so.

That's right, according to Chicago Marathon director Carey Pinkowski, sanctioning rules prevent Armstrong from running the Oct. 7 Bank of America Chicago Marathon.
