Found this competition on a blog - Race for Life runners can get the chance to add up to £100 to their Race for Life sponsorship in a weekly prize draw from AXA PPP healthcare. You need to already have at least a £50 sponsorship and a Just Giving Page to enter. The prize draws will run every Friday, until the 3rd of August.
AXA PPP healthcare members can win £200. Good luck!
