Joining guest host Rachel Feltman to answer questions from long-distance runners is Dr. Brandee Waite, Director of UC Davis Health Sports Medicine. Over the past 20 years, Dr. Waite has directed the medical care for multiple marathons and ultra-marathons, and has served as a team physician for USA Track & Field.
