The Only Way Is Essex star James Argent has surprised his friends by saying he plans to run the London Marathon.
The 23-year-old chubby reality star is apparently to take part in the event in April.
However, he has been warned by health experts that he will need to quit his unhealthy eating otherwise he will struggle with the race.
Arg, who recently broke up from his long-term girlfriend Lydia Bright, was filmed in the latest TOWIE episode pigging out on pizzas and sandwiches.
Running experts say you should train and run regularly for a year before trying to complete a marathon.
Keith Anderson, Adidas training expert, told the Daily Star: "It's a gruelling event that requires good endurance.
"People try to cram in the training or they set off thinking they can run the whole thing and they end up facing a really horrible ten-mile walk at the end.
"If he's not trained then everything is going to chafe, everything is going to ache and he's going to have a miserable day."
A source added: "I've not heard that Arg has done any real training."
