Ironman triathlon is a gruelling event consisting of a 3.8km swim, followed by a 180km ride, topped off with a 42.2km run. In general experienced triathletes with a long training history compete, as many years of training are required to undertake an event of this duration. The biggest age group is 30-40years, but it's not uncommon to see athletes in their 50's and 60's competing also.  Ironman competitors often need to complete specified half ironman races and place high enough in their age group to earn a coveted ironman spot.

This ultra-endurance event presents many nutritional challenges to meet extreme fuelling and hydration requirements and without the support of these basic elements for survival, and a strategic plan to meet base requirements, it may result in a failure to complete the event. This resource has been designed for the specific needs of an ironman competitor.
