Tom Cruise has become obsessed with running since Katie Holmes ran the New York marathon.

Holmes ran the race in 2007 and now Cruise is reportedly deciding whether or not to run one himself.

A source told the Daily Mirror: "When he saw her running that race, something kicked inside him and he decided he'd have to do it - possibly in Boston. That's the kind of guy he is."

Cruise has vowed to beat Holmes time in New York, where she complete the race in five hours, 29 minutes.

Holmes entered the the marathon just a year after giving birth to the pair’s daughter Suri.
