Planning what to eat during a race can be overwhelming. With so many variables, it’s hard to determine what the “right” answer is for you. When deciding what to eat and drink, we think it’s helpful to break it down by looking at the nutrients your body needs.

A successful nutrition plan takes into account the amount of calories your system can handle in an hour, and it should also factor in your body’s need for electrolytes, amino acids, water, and protein.

Marathon Nutrition PlannerWhen thinking about your nutritional need for a race or training session, it’s important to remember that everyone is different and every day is different. For example, body size, air temperature, activity type, intensity, and personal preference will all affect your nutritional need.

That’s why GU has products are designed to be mixed and matched. For example, if you prefer to drink you calories, you can bottle up your fuel using Roctane Energy Drink.
