Kate McCann is preparing to run next month's London Marathon in aid of the Missing People charity.
Kate, who will be completing the 26.2 mile route just weeks before the six-year anniversary of her daughter Madeline's disappearance, aims to raise £10,000.
She has raised nearly £2,000 of her target so far.
Two years ago Kate and her husband Gerry, of Rothley, completed a 10km run in aid of the same charity.
Writing on her Just Giving page, Kate said: "This year (old, crumbly body allowing) I will be running the London marathon in aid of Missing People as the charity celebrates its 20 anniversary.
"If I'm honest, I would happily have gone through my life without ever contemplating running a marathon, or even a half-marathon for that matter!
"However, knowing what it's like to be living with a child missing and believing very strongly in what the workers at the charity do in helping other families like mine, I realised it was a challenge that I had to take."
