Singer inspired by pal Katie Holmes
The fashionista has been stocking up on carbs and hitting the running machines in a bid to boost her stamina.
‘It was meant to be a big secret. She’s been training for months with the main goal of running in the New York Marathon,’ a source tells Now.
‘But if she doesn’t feel ready, she’s planning to do the one in Los Angeles in February next year.’
Celeb chef Gordon Ramsay has also confirmed that she’s eating more because she wants to compete.
It is thought she’s determined to beat pal Katie Holmes‘ time when she ran the 26-mile race last year.
‘Katie finished it in 5 hours and 30 minutes,’ a pal reveals.
‘And, in a friendly spirit of competition, Posh wants to beat her time and finish within five hours.’
The New York Marathon takes place on 3 November.
