Send us your story: Are you running the Virgin London Marathon for charity?

Many runners are currently pounding the roads of Norfolk in preparation for this year's Virgin London Marathon - and we want to hear your stories.

If you would like your marathon fundraising story to be featured, then send us your details via www.iwitness24.co.uk

Get someone to take some photos of you training in your running gear, or fancy dress, if that is what you are planning to run in.

Then go to iwitness24.co.uk and send us your photos along with your name, age, location and occupation, and details of how people can donate to your cause.
