Triathlon Training Nutrition and Diet
The basic concept is to eat for training as you would an actual competition. This enables you to test out which foods, beverages and meals work best with your body for your specific race distance. Competing on a full stomach is uncomfortable, doesn’t allow the best digestion, and can impair performance so you’ll want to be sure and have a higher carbohydrate meal 3-4 hours prior to a full training session with all three sports. This meal should contain a moderate amount of protein (~30 grams) and a low amount of fat, followed by about 2 cups of water. Races are usually first thing in the morning making this timing impractical, so load up on carbohydrates the night before and practice early mornings while following the below.
About an hour prior to the event, eat a snack with around 30-60 grams of carbohydrates and about 10 grams of protein, again lower fat and with a cup of water. Consumption of this snack is critical as there is no intake during the first swim leg and fueling during the bike and run legs will likely be limited to sports drinks. The goal is to create a constant supply of blood glucose throughout the triathlon. Hydration for thermoregulation is critical, so drink ½ – 1 cup of a lightly salted solution of 5-8% carbohydrate (10-20 g CHO and ~110 mg Na+ per cup) every 15 – 20 minutes during competition and training. Everyone’s body is unique and gut tolerance varies, so find your ideal foods and volume to ensure peak performance.
