Runners will be given a log sheet to record their 100K before being rewarded with a spinning propeller Spitfire 100K Challenge medal.
Entry costs £20 per person and all proceeds from the Spitfire 100K Challenge will go towards the RAF100 Appeal, a joint venture between the Royal Air Force and four major RAF charities – Royal Air Force Benevolent Fund, Royal Air Forces Association, Royal Air Force Charitable Trust and the Royal Air Force Museum.
