For every person who uploads a video to my YouTube channel of themselves, friends or family doing the 'running man' dance, Virgin Money will donate £5 to my Marathon sponsorship, up to a maximum of £10,000. It's a great way to get involved and have a bit of fun at the same time.

To find out what it's all about, take a look at the video above and submit your 'Running Man' dance video at http://www.youtube.com/video_response_upload?v=cUr38QDFWjg (less info)
