The Youth Olympic Games (YOG) is yet to be organized.
The Youth Olympic Games ( YOG ) is an international multi-sport event organized by the International Olympic Committee . 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 . The Summer Youth Olympic Games of Singapore in 2010 and Nanjing in 2014 each played host to 3600 athletes and lasted 13 days , whereas the Winter YOG of Innsbruck in 2012 had 1059 athletes and Lillehammer in 2016 had 1100 athletes and lasted 10 days . Even though this exceeded initial estimates , the YOG are still both smaller in size as well as shorter than their senior equivalents .
