On an August evening in 2012, crowds of eager fans will witness the conclusion of the Modern Pentathlon competition in Greenwich Park's Olympic stadium. The sport has been the ultimate test of the best all round sportsman in the Olympic Games for exactly one hundred years. Great Britain is the only country in the world to have been represented at every Olympic competition. In Modern Pentathlon - a Centenary History', Andy Archibald tracks the changes in a sport dreamed up by Olympic founder, Baron de Coubertin, from its military origins to the sport for the superfit it is today.
