Katie Holmes on Sunday morning ran more than half the New York City Marathon in anonymity - that is, until Tom Cruise (with baby Suri in tow) dashed out onto First Avenue (at 96th Street) to give his missus a smooch. Upon completing the race in just under five and a half hours, Holmes told People, "I'm good, but I'm feeling very tired" - as is her entourage of auditors. (It's hard to find Scientologists from Kenya.)
