Written by acclaimed Ironman expert Bob Babbitt, The Complete Ironman captures the spirit, excitement and endeavour of this globally respected sports event with more than 150 amazing images included many previously unpublished.

The Complete Ironman is a unique illustrated book explores every aspect of the competition, from its history and legendary competitors to its major global events, and provides expert practical advice on how to prepare and succeed at such a demanding yet revered athletic challenge. But what is Ironman? It is the combination of a race, an accolade and an aspiration.

For more than 40 years it has been, arguably, the toughest athletic event on the planet, presenting competitors with an almost impossible physical challenge: a 2.4-mile (3.8km) swim, 112-mile (180km) cycle ride and 26.2-mile (42km) marathon run. Even so, Ironman attracts thousands of entrants every year, and has a unique standing and aura in the sporting world.

The number 140.6 is a magic one for Ironman triathletes, as it is the total mileage covered in a race, and it's an inspiring goal for competitors around the world.
