Time to Carb Load, Runners!

For everyone running in the Baltimore Running Festival, congrats! You made it this far, and your just a couple days before the big event. For the runners of the full marathon, I hope you’ve begun your carb load! Carb loading involves eating lots of carbohydrate-rich foods before an endurance event longer than two hours to load up your muscles with glycogen (aka stored carbohydrates). We can only store a small amount of carbs in our muscles—one to two hours max at hard effort of exercise. We have hours of fat to burn, but using fat for fuel is far less efficient than glycogen, so we need to maximize the carbs stored before we hit the start line by carb loading, eating breakfast on race day and supplementing with carbs on the course, or we risk an…ahem…uncomfortable finish.

The carb load doesn’t necessarily require us to eat lots more food. If you over do it by forcing down more calories than you need, you may feel bloated, or you could even be carrying extra poundage to the start line. Instead, think of it as eating about the same amount of calories, but more of it from carbohydrate, with less fat and protein. I approach it by considering meals and snacks I already eat and making adjustments to proportions and ingredients.

Example: Instead of my usual oatmeal with tons of seeds and nuts, I enjoy oatmeal with fresh & dried fruit and I add a bit of maple syrup to it. In place of my normal big green salad for lunch, I turn that salad into a wrap and add a side of roasted potatoes. In place of a snack of a banana and peanut butter, I might have banana slices on a piece of toast. 

Some simple tips for you below to get 3/4 or more of your calories from carbohydrate over the next couple days…

Enjoy fruit—including bananas, grapes, fresh dates and dried fruits. Avoid eating nuts

Enjoy lots of starchy vegetables that you tolerate well, like white potatoes and sweet potatoes (avoid eating them in sauces with lots of fat

Enjoy juice or smoothies in small amounts. Drink 100% real juice and avoid sugar-free like the plague. 

If you tolerate them, you can enjoy bread, rice, pasta, etc. Bread and pasta made with white flour are acceptable during this period, especially the day before the event

Enjoy a bit of honey and maple syrup if you like them

For the Day Before Your Race:

Do NOT try anything new!!!

Avoid alcohol

Avoid highly processed food like chips, snack cakes, etc.

Avoid high fiber foods

Try eating a number of carb-rich snacks rather than three large or heavy meals

Your biggest meal is not the night before your race—it’s the night before the night before.

The night before your race, finish your reasonably portioned carb-rich dinner a full 12 hours before your start to allow for proper digestion.

And of course on race morning, you’ll eat the breakfast that you’ve practiced throughout your training season.
