Unlikely reports have emerged that Pete Doherty is set to run the London Marathon next year.

The troubled Babyshambles rocker has apparently already started training for the demanding 26-mile road race with his former landlord, radio DJ Ralph Bernard.

A source said: "Ralph knocked on Pete's door one day and they went for a run. Despite being completely out of shape, Pete enjoyed it and he's been out again and again.

"The runs went so well, Ralph suggested that Pete try a marathon."

Pete's reps appear to be going along with the joke and have refused to rule out the possibility, saying: "There is some truth to this - you never know what could happen."

The 28-year-old junkie rocker has also been seen meditating and doing press-ups in a bid to clean up his act.

The source continues: "He thinks that running is a great way to get back in shape - especially after piling on the pounds in rehab.

"He knows that people will be surprised by his efforts to be healthier but he really wants to turn over a new leaf."

Pete will be keeping his enegry levels up with his new addiction - mince pies.

He reveals: "It is going to be mince pies for me this Christmas. I have got a massive order on the way."
