The Intercalated Olympic Games were to be a series of International Olympic Games halfway between what is now known as the Games of the Olympiad. This proposed series of games, intercalated in the Olympic Games cycle, was to always be held in Athens, and were to have equal status with the international games. However, the only such games were held in 1906.
These Games also were the first games to have all athlete registration go through the NOCs. They were the first to have the Opening of the Games as a separate event; an event at which for the first time the athletes marched into the stadium in national teams, each following its national flag. They introduced the closing ceremony, and the raising of national flags for the victors, and several more less visible changes now accepted as traditional.
Walking events were introduced into the athletics progamme.
At the Games notable performances came from Francisco Verri (Italy) who won three golds in cycling and Gudbrand Skatteboe (Norway) with three shooting golds. Athletes who added to the Olympic titles they had won in 1904 were Archie Hahn in the 100m, Meyer Prinstein in the long jump and James Lightbody in the 1500m. Medals from the intercalated Games are now not generally included in Olympic records but if they were each if these Americans would have had four golds in total from the two Games. Ray Ewry won two more golds in standing jumps to take his total to eight golds since 1900.
For Britain golds were won by Henry Hawtrey in the five miles and Gerald and Sidney Merlin in the Trap Shooting events. Con Leahy in the high jump and Peter O’Connor in the triple jump won gold medals for Great Britain although they were Irish athletes.
