Jenny Hadfield is the real deal. Totally committed to her clients and her craft, Jenny has focused her career and her considerable talents on inspiring and motivating runners. The curricula she designed for the Podrunner: Intervals series continue to receive rave reviews from my listeners to this day, and three-fifths of the series literally would not exist without her. I am amazed by her drive, her energy, and her unflagging commitment to keeping the world running.
