Great Britain and Argentina in race to host 2018 Summer Youth Olympics Medellín in Colombia and Guadalajara in Mexico are also bidding for the event, and other contenders have until March 1 to register their intentions. The IOC will produce a short list of Candidate Cities in January 2013, before announcing the winning Host City in the summer of 2013. Among the many attributes that Glasgow has to offer the Olympic Movement is the fact that, as Host City of the 2014 Commonwealth Games, a great deal of the required infrastructure will already be in place. Glasgow also has outstanding leadership, a strong dedication to sport and will benefit greatly from the experience of hosting a major international multi-sport competition in 2014. The Youth Olympic Games have quickly established themselves as an important and inspirational event in the international sporting calendar. We know the bidding process will be highly competitive, but we are confident that in Glasgow we have an outstanding Candidate City. The 2018 Youth Olympics will involve approximately 3,600 young athletes, aged 15 to 18, participating across all of the 28 summer Olympic sports in 12 days of competition.
