Katie Makes a Run for It!

Katie Holmes is strapping on her running shoes -- perhaps as we speak -- but not to make a mad dash from the mothership. No, even more peculiar, she's running in this Sunday's New York City marathon!

TMZ just spotted the Katie and her first husband docking their SUV at the Carlyle Hotel in New York, just steps away from Central Park, where the Marathon ends. As OK! magazine reports, Katie will be joining Lance Armstrong and about 37,000 other runners making the 26-mile trip around the five boroughs. OK! adds that Katie's folks will be there to cheer her on when she makes it to the end.

Suri's father will also be waiting at Tavern on the Green for Katie to finish -- joystick and fresh batteries in hand.
