In On Pace, acclaimed running coach and author Matt Fitzgerald reveals how conventional training and device overdependence keep runners from accessing the full power of pacing. With a mix of fascinating science and compelling stories from every corner of the sport, Fitzgerald shows that pacing is the art of finding your limit-running at a pace to finish the workout or cross the finish line completely out of gas.
