Special Olympics is the world's largest sports organization for children and adults with intellectual disabilities providing year-round training and activities to 5 million participants and Unified Sports partners in 172 countries. Special Olympics competitions are held every day, all around the world—including local, national and regional competitions, adding up to more than 100,000 events a year. Like the International Paralympic Committee, the Special Olympics organization is recognized by the International Olympic Committee; however, unlike the Paralympic Games, Special Olympics World Games are not held in the same year nor in conjunction with the Olympic Games.
The Special Olympics World Games is a major event put on by the Special Olympics committee. The World Games alternate between summer and winter games, in two-year cycles, recurring every fourth year.
