The 1908 Olympic Games, Games of the IV Olympiad, were originally awarded to Rome, but were reassigned to London when it became apparent that Rome would not be ready. A 68,000-capacity stadium was constructed at White City, in West London to host the athletics, cycling and swimming competitions, whilst most other events took place around London. These Games were the first to include Winter events and for the first time athletes marched into the stadium by nationality at the opening ceremony.
Great Britain came top of the table winning a total of 146 medals. Lasting a total of 187 days, or 6 months and 4 days, these games were the longest in modern Olympics history.
