In 1991, the IOC recognized the ITU as the sole governing body for the sport of triathlon at its 97th session in Birmingham, UK. In 1993, the Pan American Games approved triathlon for competition at the 1995 Pan Am Games in Mar del Plata, Argentina. Then in September 1994, triathlon was added to the Olympic program as a medal earning sport at the 2000 Olympic Games in Sydney, Australia. Organisations The International Triathlon Union (now known as World Triathlon) was founded in 1989 as the international governing body of the sport, with the chief goal, at that time, of putting triathlon on the Olympic program. The World Triathlon sanctions and organises the World Triathlon Series and the World Triathlon Cup races each year, with annual world champions crowned each year for elite pro-triathletes, junior pro-triathletes, and age-group athletes. World Triathlon races are conducted in a draft legal format for the bike leg, whereas drafting is not permitted at the amateur level. In addition, the ITU has a Long Distance Triathlon series. The World Triathlon Corporation (WTC) is a private company that sanctions and organises the Ironman and Ironman 70.3 races each year. These races serve as qualifying events for their own annual World Championships. The Ironman World Championship is held annually in Kailua-Kona, Hawaii in October while the Ironman 70.3 World Championship is held in September and changes location each year. The "Ironman" and "Iron" brands are property of the WTC. Therefore, long-distance multi-sport events organized by groups other than the WTC may not officially be called "Ironman" or "Iron" races. For its part, the ITU does not sanction WTC races; however, USA Triathlon (USAT) uses a combination of World Triathlon and WTC rules to sanction WTC's branded events. Many other organisations exist beginning with local clubs that may host a single small race once per year to companies like the Challenge Family brand that produces long-distance events around the world, which includes events like Challenge Roth. International Ultra-Triathlon Association (IUTA) is the official governing body of Ultratriathlon, which involves triathlon in distances longer than an iron-distance race. Additionally, each nation, generally, has a sanctioning body for triathlon events in their respective country with regard to athletes competing and qualifying for Olympic competition. The Professional Triathletes Organisation (PTO), an athlete-owned body that represents non-drafting professional triathletes, was launched in 2016. The organisation focuses on promoting the athletes and their performances
