The Youth Olympic Games (YOG) is an international multi-sport event for athletes between 14 and 18 years old, organized by the International Olympic Committee. The games are held every four years in staggered summer and winter events consistent with the current Olympic Games format, though in reverse order with Winter Games held in leap years instead of Summer Games. The first summer version was held in Singapore from 14 to 26 August 2010 while the first winter version was held in Innsbruck, Austria from 13 to 22 January 2012.
