One of the things that make triathlon so interesting is the diversity of the athletes who come to the sport. Triathlon can be thought of as the “melting pot” of all sport. There is not one athletic background that can “make” a triathlete. An advanced swimmer, cyclist, or runner, may have some advantage starting up in the sport, but the training approach, as well as the mental outlook, of what made them an advanced athlete in that sole sport, may have to be adjusted, once initiating triathlon training.
