Sally “Sal” Edwards is no stranger to being at the front of endurance races and the forefront of revolutions in running retail and exercise physiology. She didn’t pick up running until after college, but eventually became a Nike-sponsored runner and competed in a number of marathons, including the inaugural US Olympic Marathon Trials in 1984. Her marathons were interspersed with ultramarathons—In 1980 she won the Western States Endurance Run—both of which were ultimately supplanted by triathlons. She also founded two companies—Fleet Feet Sports and Heart Zones, of which she remains CEO—and has shared her expertise in training methods and exercise physiology across 24 books and over 500 articles.
