Why is the Half Iron-Distance the most popular triathlon distance? Because it is the perfect length for busy athletes with demanding career and family responsibilities. Full Iron-Distance races require such painstaking planning and sacrifice that it's difficult to keep life in balance. The Half Iron-Distance is accessible, while remaining challenging. Also known as the "70.3" for the sum of its 1.2 mile swim, 56 mile bike ride, and 13.1 mile run, the half-iron triathlon is not simply a race for which an athlete can use a full-iron training regimen chopped in half. Doing so would in no way approach maximizing an athlete's performance. The races are performed at completely different intensity levels, with completely different approaches. As a result, the training is completely different. IronFit Secrets to Half Iron-Distance Triathlon Success does for the half-iron what Be IronFit has done for the full-iron. It provides three sixteen-week training programs--Competitive, Intermediate, and "Just Finish"--and details everything an athlete needs to know to successfully prepare for and maximize performance at this racing distance.
