Logging your intake. I can’t tell you how important it is. The number one piece of advice I give to my athletes, regardless of if they are just starting out, or a seasoned triathlon veteran, is to start keeping track of what they eat! Even if you have (or think you have) control over nutrition, logging intake is a great learning tool. Besides tracking calories, one can monitor grams of carbohydrate, protein, fat, and fiber. All of which can make or break your training session, or race!
