But why? In this episode we investigate the evidence around nutrition, the immune system, and illness in athletes, and come to a conclusion of what you can do to prevent getting sick during those hard training blocks, and bounce back quickly when illness does strike.   Fueling Endurance eBook | T -12 Race Nutrition Course | Practitioner Resources The Fueling Endurance eBook contains answers to 49 of the most common nutrition questions that runners, cyclists and triathletes ask, and contains insights, tips, and quotes from experts and athletes.  The T -12 self-guided course will help prepare you for your next event, with online tools, guides, information and instructions to take you through the 12 weeks leading up to race day.
