The Olympic Games are considered the world's foremost sports competition with more than 200 nations participating. The Olympic Games are held every four years, with the Summer and Winter Games alternating by occurring every four years but two years apart.
The Olympic symbol, better known as the Olympic rings, consists of five intertwined rings and represents the unity of the five inhabited continents (Africa, America, Asia, Australia and Europe). The coloured version of the rings—blue, yellow, black, green, and red—over a white field forms the Olympic flag. These colours were chosen because every nation had at least one of them on its national flag.
An Olympic medal is awarded to successful competitors at one of the Olympic Games. There are three classes of medal: gold, awarded to the winner; silver, awarded to the 1st runner-up; and bronze, awarded to the second runner-up. The granting of awards is laid out in detail in the Olympic protocols.
