Greg McMillan

Greg McMillan is an American running coach, exercise physiologist, and author known for developing training programs and predictive race calculators used by recreational and competitive runners. He has worked with endurance athletes across distances from 5K to ultramarathons and is associated with coaching platforms, running publications, and endurance events. His work bridges applied physiology, marathon preparation, and training-plan design.

Early life and education

McMillan grew up in the United States and pursued studies that combined exercise physiology-related inquiry with applied endurance training. He completed undergraduate and graduate coursework focused on human performance and physiology, engaging with academic communities connected to institutions such as University of Colorado Boulder, Stanford University, and University of Michigan through conferences, workshops, and professional networks. During his formative years he connected with coaches and researchers from organizations including the American College of Sports Medicine, USA Track & Field, and the Road Runners Club of America, which shaped his practical approach to run training and athlete development.

Running career

As an athlete and coach, McMillan participated in road racing and track events spanning 5K, 10K, half marathon, and marathon distances. He competed in regional and national races that placed him in the same competitive environment as athletes associated with the Boston Marathon, New York City Marathon, and collegiate programs such as Oregon Ducks track and field and Stanford Cardinal track and field. His racing experience informed collaborations and exchanges with prominent figures in distance running circles, including coaches from Nike, Brooks Running, and independent coaches linked to clubs like The Boston Athletic Association and New York Road Runners. Through racing and training he interfaced with athletes who have competed at meets like the USATF Championships, IAAF World Championships in Athletics, and the Olympic Games trials.

Coaching and training philosophy

McMillan’s coaching emphasizes individualized pacing, periodization, and physiological markers such as lactate threshold and VO2 max. His methods reference work from sport scientists affiliated with Cooper Institute, Gatorade Sports Science Institute, and laboratories at universities such as University of Colorado Boulder and University of North Carolina that study endurance adaptations. He integrates pacing strategies familiar to coaches of elite athletes from programs like Bowerman Track Club, Oregon Track Club, and collegiate staffs at University of Oregon and University of Colorado while tailoring plans for recreational runners connected to community groups like Parkrun and clubs affiliated with the Road Runners Club of America. McMillan’s plans account for race-specific preparation for events including Boston Marathon, Chicago Marathon, London Marathon, Berlin Marathon, and popular trail ultramarathons such as Western States Endurance Run and Leadville Trail 100. He also incorporates cross-training approaches seen in multisport coaching communities linked to USA Triathlon and endurance methodologies promoted by coaches affiliated with Runner’s World and MapMyRun.

Publications and contributions

McMillan authored training guides and online content that provide structured marathon plans, pacing calculators, and articles on injury prevention and recovery. His publications appear alongside material from running media entities including Runner's World, Competitor Magazine, and peer coaching platforms used by members of Road Runners Club of America and subscribers to services from companies such as Garmin and Strava. He developed widely used predictive tools similar in aim to calculators referenced in analyses from VO2max research, trainers associated with Jack Daniels (coach), and programming frameworks used by professional staffs like Hansons-Brooks Distance Project. McMillan’s writing connects to larger literatures on endurance training advanced by researchers and authors from institutions such as University of Texas at Austin, Ohio State University, and Auburn University and is cited in practical guides alongside works by coaches like Arthur Lydiard and Pete Pfitzinger.

Awards and recognition

Throughout his career McMillan has been recognized within running communities and coaching circles, receiving endorsements and acknowledgments from organizations such as the Road Runners Club of America, running publications like Runner's World, and event organizers of major marathons including Boston Marathon and Chicago Marathon. His influence is reflected in testimonials from athletes who have competed at events under the auspices of USA Track & Field, USATF New England, and international races like the Berlin Marathon. He has been invited to speak and present at symposiums and clinics sponsored by bodies such as the American College of Sports Medicine and regional coaching associations.
