The running community is mourning the loss of Jeff Galloway, a beloved mentor and pioneering figure in American running, who passed away Wednesday at the age of 80 from complications related to a stroke and brain bleeding, according to Runner’s World.

Galloway, often described as an “unlikely Olympian,” dedicated his life to inspiring and educating generations of runners. Over five decades, he became a formative voice in the running movement, tirelessly promoting the sport and highlighting the physical and mental benefits it provides. His infectious enthusiasm and innovative approach helped countless people embrace running as part of a healthier lifestyle.

Perhaps most notably, Galloway was the pioneer of the run/walk method—also known as the “Galloway Method” or “Jeffing”—which encourages runners to incorporate walking intervals into their training. This method revolutionized long-distance running, making marathons and races more accessible to beginners and helping veterans avoid injury. His techniques and coaching philosophy left a lasting impact on recreational and competitive runners alike.

Beyond his methods, Galloway was a mentor, coach, and motivator who believed that running could transform lives. Through clinics, books, and seminars, he reached tens of thousands, fostering a supportive community and helping runners achieve personal goals while celebrating the joy of movement.

Galloway’s legacy will endure not only through the millions who ran his way but also through the spirit of encouragement and inclusivity he championed. Friends, family, and the global running community remember him as a visionary who combined athletic excellence with teaching, humor, and heart.
