The 45 year old lieutenant colonel in the Royal Army Medical Corp, who has not been named, was taking part in the event near Point de Hoc which is famous for being one of the toughest cliffs to conquer during the landings in 1944.
He was with his comrades taking part in a D-Day fund raising run for the British Limbless Ex Service Men’s Association, a British charity that directly supports servicemen and women who lose limbs, the use of limbs or eyes or the sight of an eye in the service of their country.
He became ill just before 10am and although firemen from Bayeux and Grandcamp-Maisy were quickly on the scene and an emergency first aid helicopter arrived, the serviceman was pronounced dead at the scene by a doctor.
French officials said that an autopsy will be carried out to establish the exact cause of the officerâ€™s death which is standard procedure for deaths in France. His wife, who was nearby, was treated for shock at Point du Hoc by first aid personnel.
â€˜With deep regret the MoD can confirm that a serving soldier from the Royal Army Medical Corps died suddenly near Bayeux, France on 6th June,â€™ said a Ministry of Defence spokesperson in London.
â€˜Our thoughts are with the individualâ€™s family and friends at this difficult time. We can confirm that the individual was undertaking a D Day Fundraising run on behalf of BLESMA. The individualâ€™s family have been informed of the death and are being supported accordingly,â€™ the spokesman added.
The 100 feet cliffs at Point de Hoc was scaled by highly trained American rangers on the morning of D-Day in 1944. It was a key point to be captured between Utah and Omaha beaches as the Germans had a large battery there that was part of the Atlantic Wall which threatened the boats bringing men ashore.
Today the site has been largely left as it was during the battle with huge craters and many of the original fortifications. A new museum is being built which will be open in time for the 70th anniversary of D-Day next year.
