Jeff's quest for the injury-free marathon training program led him to develop group training programs in 1978, and to author Runner's World articles which have been used by hundreds of thousands of runners of all abilities. His training schedules have inspired the second wave of marathoners who follow the Galloway RUN-WALK-RUN™, low mileage, three-day, suggestions to an over 98% success rate.

Jeff has worked with over 200,000 average people in training for specific goals and is the inventor of the Galloway RUN-WALK-RUN™ method. Jeff is an inspirational speaker to over 200 running and fitness sessions each year.
