Every year, over 330 crews from around the world participate in the Great River Race - London's River Marathon. MediaCom are entering three boats this year to raise money for Rays of Sunshine - a charity that brightens up the lives of seriously ill children in the UK by granting wishes. MediaCom is aiming to raise at least £15,000 pounds in total, with each team targeting a minimum of £5,000 pounds each. Each wish is approximately £1500, meaning MediaCom has the opportunity to help Rays of Sunshine grant wishes for about 10 seriously ill children.  Please help us by donating and sharing our cause.
