From the fastest marathoner in the world over fifty—and maybe the planet’s most determined underdog—an inspiring tale of resilience, redemption, and personal transformation. Born into a broken family in Somerville, Massachusetts, just outside of Boston, Ken Rideout grew up in a household persistently scarred by drugs and crime. At just eighteen, he found himself working as a corrections officer in a prison where his stepfather had been incarcerated, and his brother would later serve time. Despite the bleak expectations set by his family, Ken harbored dreams far beyond the confines of his upbringing. Ken eventually broke free from the gritty streets of Somerville to the high-stakes world of Wall Street, where he carved out a successful career with top firms like Cantor Fitzgerald and Crédit Agricole. Yet, beneath the veneer of success, he battled a decade-long addiction to opioids, spending his hard-earned wealth on pills. The turning point came with the adoption of a daughter from overseas—a wake-up call to become the father and man he always dreamed of being. Running became Ken’s salvation. With unwavering determination, he willed himself to run vast distances. In three years, Ken transformed from a “running nobody” to the world’s fastest marathoner over fifty. His mantra: Win—or die trying . In the book, Ken shares his awe-inspiring achievements, including, at age fifty-two, winning the Masters (50+) Marathon World Championships in Chicago and conquering the Gobi March ultra-marathon, one of the world’s toughest races. Through sheer resilience and grit, Ken rewrote his story. “RIDEOUT DOESN'T HOLD BACK…even those more inclined to sitting at home [than running] will be fascinated by his prickly personality and undeniable enthusiasm.
