Become a Better Triathlete in 63 Minutes with Dr. Marc Bubbs

Dr. Marc Bubbs is the author of a book every triathlete needs to read. PEAK: The New Science of Athletic Performance, details the items all endurance athletes (and any athlete for that matter) need to take seriously -- and what new fads (and old standbys) really don't amount to anything for improved performance.  We talk sleep, supplements, food, and more.
