9 seconds. That’s how long it took for Scott Rigsby’s life to come crashing down around him. 16 hours, 42 minutes, 46 seconds. That’s how long it took for Scott Rigsby to make history. One day when Scott Rigsby was eighteen years old, he was riding in the back of a pickup truck that was towing a three-ton trailer. When the trailer was clipped from behind by an eighteen-wheeler, Scott was thrown over the side and dragged 324 feet before being pinned under the trailer. Later, at the hospital, his right leg was amputated—the first of twenty-six surgeries he would endure over the next twelve years, including the loss of his other leg. Doctors said it would be more than a year before he could expect to walk again—let alone run. Nine years later, Scott did the unthinkable . . . On October 13, 2007, after arduous training, he became the first double-leg amputee using prosthetics ever to cross the finish line in the sporting world’s most grueling and prestigious event, the Ford Ironman World Championship triathlon in Kailua-Kona, Hawaii. Unthinkable documents Scott’s remarkable journey from the devastating crash that claimed both of his legs, and from his subsequent battle with depression and alcohol, to the dawning realization that God had a greater plan for his life. The unthinkable courage, determination, and faith Scott demonstrated in training for and competing in the Hawaiian Ironman triathlon will inspire and amaze you.
