The most common distances are the double, triple, quadruple, quintuple and deca triathlon.

2011 Ironman 70.3 World Championship Province, China, were canceled. The Tianjin Sports Bureau (TSB) was unable to obtain the required sanctions from the China Triathlon Sports Association (CTSA) to conduct the event. Murphy Reinschreiber, managing director of the Asia Pacific region for WTC stated that "TSB simply failed to provide all of the documentation necessary for CTSA to process the sanction." WTC is offering a full refund of entry fees to all athletes who were scheduled to compete at Ironman China and Ironman 70.3 China. Additionally, all athletes were offered a complimentary race entry into any of the 2011 Ironman and Ironman 70.3 races. WTC
