This book revolves around the central idea of how triathletes manage the multiple identities of father, husband, worker and athlete in their day-to-day life, thus earning the title of Iron Dad. Taking part in the 140.6-mile triathlon requires not only great physical stamina but also immense emotional and mental strength. The author has beautifully captured this journey from beginning to end, i.e. from the time when a man starts thinking about registering, to the process where being an IRONMAN becomes his identity, how he juggles these multiple identities, how he contemplates leaving the race halfway through, to finally reaching the finish line.
