Dr. Marty Hoffman is Professor of Physical Medicine & Rehabilitation at the University of California Davis, Chief of Physical Medicine & Rehabilitation at the VA Northern California Health Care System, former Director of Research for the Western States Endurance Run (2006-16), former team physician for the US Biathlon Association (1988-95), and Chief Medical Officer for the Ultra Medical Team. He has published over 150 original scientific publications mostly related to applied exercise physiology with focus on human locomotion, human performance and exercise-associated hyponatremia. His clinical work has involved cardiac rehabilitation, musculoskeletal medicine and sports medicine. He has been a Fellow of the American College of Sports Medicine since 1989 and serves on multiple editorial boards. He has been a competitive cross-country skier or distance runner for most of his life, and still enjoys exploring his own limits…..though at a much slower pace than in the past.
Ricardo Costa, PhD, Registered Dietitian, Registered Sports Dietitian
Dr. Ricardo Costa is an academic, researcher, consultant and practitioner in sports dietetics and extremes physiology, based in the Department of Nutrition & Dietetics at Monash University, Australia. His publication outputs, in exploratory field and laboratory controlled intervention research, includes focus on the nutritional and hydration status in ultra-endurance running, physiological responses to ultra-endurance in the heat, impact of endurance exercise on the immune system and nutritional counter-measures, and the impact of endurance exercise (with and without heat-stress) on gut health including prevention and management strategies. As a sports dietetic practitioner, he has provided nutritional support in a variety of sports (i.e., teams, aquatic, combat, endurance, ultra-endurance, adventure and expedition) ranging from junior development to veteran athletes, and from recreational to world championship and Olympic athletes. Before entering a career in academics he was a professional trialthlete/duathlete competing on the World and European circuit between 1994-2003.
Dr. Pierre Sallet has a PhD in Sports Science. For more than 7 years he served as a physiologist for a variety of professional teams in football, basketball, cycling and individual disciplines at an elite level, such as marathon running and triathlon. He was a former national level athlete (30.53 mins for 10km) and is an internationally recognized expert on the battle against doping. He is President of the Athletes For Transparency (AFT) association with aim to preserve sports ethics, and he also promotes healthy trail running practice as a founding member of the International Trail Running Association (ITRA).
