Anyone that’s done an Ironman will tell you that nutrition is the “4th discipline”. You can be at the top of your game in swimming, biking and running, and still not reach your race day potential due to sub optimal race fueling. Eat too much and you’ll be slowed down by stomach issues, bloating, nausea or just general discomfort. Eat too little and you’ll deplete your glycogen stores which are needed for optimal endurance efforts. Through metabolic testing, you can calculate how much fat and carbohydrate fuel you burn per hour at YOUR race pace, taking the guess work out of your optimal energy intake requirements for training and racing.
