In the Fall of 2006, Dean Karnazes, known as "the Lance Armstrong of the running world", took on the ultimate challenge: running 50 marathons in 50 states in 50 consecutive days. Dean set off in a caravan packed with fellow runners, with nothing more than a roadmap and a determination that defied all physical limitations.

The greatest athletic performances spring from the mind, not the body. Elite athletes have known this for decades, and now science is learning why it's true. In his fascinating new book, How Bad Do You Want It?, coach Matt Fitzgerald examines more than a dozen pivotal races to discover the surprising ways elite athletes strengthen their mental toughness.

From the national best-selling author of Racing Weight, Matt Fitzgerald exposes the irrationality, half-truths, and downright impossibility of a "single right way" to eat and reveals how to develop rational, healthy eating habits.

A breakthrough program for triathletes - beginner, intermediate, and advanced - showing how to balance training intensity to maximize performance - from a fitness expert and elite coach. Cutting-edge research has proven that triathletes and other endurance athletes experience their greatest performance when they do 80 percent of their training at low intensity and the remaining 20 percent at moderate to high intensity. 

An endurance athlete and coach reveals how the marathon transforms the lives of everyone who attempts it - and how it has helped his own family cope with serious adversity. 

The 1989 Ironman World Championship was the greatest race ever in endurance sports. In a spectacular duel that became known as the Iron War, the world's two strongest athletes raced side by side at world-record pace for a grueling 139 miles. Driven by one of the fiercest rivalries in triathlon, Dave Scott and Mark Allen raced shoulder to shoulder through Ironman’s 2.4-mile swim, 112-mile bike race, and 26.2-mile marathon. After 8 punishing hours, both men would demolish the previous record - and cross the finish line a mere 58 seconds apart.

Matt Fitzgerald has already made a name for himself in the endurance-sport community with books like 80/20 Running, How Bad Do You Want It?, and Iron War. He is an accomplished amateur runner, but if he follows the training, nutrition, and lifestyle of an elite runner, just how fast could he go? He is approaching his mid-40s, so the time to do this is now. He at last has the financial means to do nothing but train.
