Armstrong continues for NYC Marathon

Lance Armstrong is continuing with his plans to run in the New York City Marathon on November 5th despite some fears.

"Initially I had this idea that I would run more when I retired from cycling and try and do a marathon a year, and just choose different locations and use that as my sporting challenge but I have to tell you its been tougher than I thought," said Armstrong, who retired at the end of last year's Tour de France. "The training and actual physical pounding is tougher than I thought."
