Anyone who goes the distance in the New York City Marathon has my respect and then some. But having done some running in my time, I’m wondering if Katie Holmes, who is after all surrounded by minders, “yes” people and Scientologists 24-7, will be able to run the entire distance this Sunday.

Like everyone else, Holmes will have to hump all the way from the foot of the Verrazano Narrows Bridge in Staten Island and up through Brooklyn, Queens, Manhattan, the Bronx and finish somewhere in southern Central Park. Life doesn’t get much lonelier or more grueling than when you’re running a marathon, and for the first time since she hooked up with Tom Cruise, Holmes will be entirely alone. No goons, no Xenu, no obsessive assistants…it’ll be entirely between herself, her leg muscles and her spirit.
