Jeff Galloway was an average teenage runner who kept learning and working harder until he became an Olympian. He is the author of the best-selling running book in North America (Galloway's Book on Running) and was a Runner's World columnist for over 20 years, as well as inspirational speaker for more than 200 running and fitness sessions each year. He has worked with over 400,000 average people training for specific goals, and Galloway's quest for an injury-free marathon training program led him to develop group training programs in 1978. Galloway is the designer of the walk-run, low-mileage marathon training program, Galloway Run Walk Run, that has an over 98% success rate.
