*The Games spanned 188 days. Although the formal opening ceremonies were not until July 13, the 1908 Games opened on April 27 with the racquets competition and ended October 31 with the field hockey final.
*For the first time ever, a stadium was built especially for the Olympics. The White City Stadium became the centrepiece of the Games and featured not only a running track but also a swimming pool, cycling oval and platforms for wrestling and gymnastics.
*It was also the first time that Olympic swimming events were not held in open water, allowing fans packed into the 66,000-capacity stadium the chance to cheer on their favourite swimmers like never before. For diving, there was a special folding tower.
*Athletes paraded behind their national flags during the opening ceremony for the first time during the London Games. It was attended by King Edward VII on July 13, 1908.
*The marathon was extended by 195 metres so that the race could start under the window of the nursery at Windsor Castle and finish in front of the stadium's royal box. This new distance of 42.195km would eventually become the official distance from the 1924 Games onwards.
*John Taylor became the first black Olympic gold-medallist. He was part of the gold-winning 4x400-metre USA team.
*The men's single-shot 100-metre running deer competition was introduced in the 1908 Games. The event consisted of a deer-shaped target that made 10 75-feet runs. Depending on the code of the event, shooters took one or two shots at the target during each run.
*The athletics events included for the first time, a relay, called "the Olympic relay". The athletes ran 200m, 200m, 400m and 800m.
*Australia and New Zealand were represented by a single delegation, under the name of Australasia.
