Your First Half-Distance Triathlon will guide any triathlete who wished to finish his or her first half-distance triathlon from the beginning of the preparation until race day. The half-distance triathlon consists of a 1.2-mile swim, 56 miles of cycling and a 13.1-mile run. It is anything but an easy option, but it represents a fascinating challenge for any well-trained endurance athlete. Considered a Long Course it covers more miles than the Olympic distance and provides the perfect stepping stone to the ITU Long Distance races and even the Ultra Distance Ironman triathlon.
