Katie Holmes Completes N.Y. City Marathon

While most fans along the 26.2 miles of the New York City Marathon's path found it hard to spot her Sunday, one keen observer (Tom Cruise) on the sidelines knew exactly what runner he was looking out for Sunday morning. Her number: F127.

Her name: Katie Holmes.

Wearing a dark FDNY baseball cap and purple tank top, Katie finished the race and was congratulated by husband Tom Cruise and their daughter, Suri Cruise, as she crossed the finish line.

Tom and Suri Cruise, as well as Tom's mother and Katie Holmes' parents, were all at the finish line to greet the runner, who was in good spirits and seemed anything but exhausted.

She made it to the bitter end around 3:30 p.m., with a final time of 5:29:58. Reunited with her daughter after the race, a smiling Holmes gave Suri Cruise a hug and kiss.

Before her arrival, inside the banquet tent set up in Manhattan's Central Park - and with his daughter at his side, Tom Cruise said that he is "very" proud of Holmes, whom he finds "inspired. She trained for three months."

At that point, any other observations about his wife were interrupted by Suri Cruise, whom Tom Cruise had to start chasing around the tent. Noted the famous father of his 18-month-old: "She's already a runner herself!"

Later, back at her hotel, with Suri Cruise now in her arms, Katie Holmes was asked by People how she felt. "I'm good, but I'm feeling very tired," she said.
