She's Britain's most successful female middle distance runner and still holds the British records for both the 800 and 1500 metres.
But ten years after she won double gold at the Athens Olympics Dame Kelly Holmes from Kent is stepping out of her comfort zone and into this year's London Marathon, which takes place this Sunday.
She hopes to raise a quarter of a million pounds for five charities, including two local ones close to her heart.
There are hundreds of community sports clubs right across the South East, and it's thanks to an army of volunteers that many of these clubs survive. This summer ITV, in partnership with the charity Join In, is aiming to get 100,000 people to sign up as volunteers. It's part of ITV's Local Heroes campaign. Dame Kelly Holmes knows only too well the importance of volunteering. Helen Plint reports.
The Olympian Dame Kelly Holmes, was in her home town of Tonbridge today to start the town's very first Dragon Race. The double Olympic gold medallist helped launch a free day of events for the local community. And she also revealed plans for a new business venture, as John Ryall reports.
Tonbridge town centre will be a hive of activity today as double Olympic gold medallist Dame Kelly Holmes starts off a dragon boat race and launches 'A Taste of Tonbridge' - a free day out for the local community to celebrate all that Tonbridge has to offer.
More than 1,000 people took to the streets of Tonbridge today for the town's half marathon. Among them a runner who'd flown in from Australia but arrived for the race without any kit. Iain McBride spoke to Andy Blundell, Kent Rodsjo and Dame Kelly Holmes.
