What To Eat The Week Of Your Marathon

You’ve been training for this marathon for months. Nerves are starting to set in. Things are becoming real. Boston is right around the corner—perhaps you’re one of the thousands that will be stepping up to the starting line to run 26.2 miles on April 20.

As you get closer to race day, you’re probably double-checking to make sure you have all of your gear in check, miles logged, and travel arrangements set. But one of the hardest parts about taper week is meal prep. Part of the week you’re home, but the final couple days you’re probably staying at a hotel and might not be thinking too much about what to eat during that time—but you should.

Tara Martine, overall women’s winner of the 2014 Rock ‘n’ Roll Savannah Marathon, is a registered and dietician, nutritionist and founder/owner of Whole Impact Nutrition, knows how important it is to rest and feed your body the right nutrients during final days before a big race, like a marathon.

“During taper week, the goal is to rest your body and fully recover from all the hard work you’ve put in,” says Martine. “Following a thoughtful nutrition program will give you confidence once your race starts.”

Start planning what foods you need to pack or pick up at a local market to prep the final few days of taper week. To help you plan, Martine offers these tips so you can focus on your pace come race day.

1 Week Before Race Day

  • Replenishing yourself with good nutrition is a critical part of taper week. Base your diet on fruits, vegetables, whole grains, beans, legumes, nuts and seeds. Avoid processed foods, fast food, junk food, refined sugars and excess oils. Your emphasis should be on consuming high-carbohydrate foods, with at least 70 percent of the total calories coming from carbohydrates. This will ensure that your glycogen stores are fully replenished for competition.
  • You might gain some weight during taper week, but don’t be alarmed. For every gram of stored glycogen, the body stores 3 grams of water, which gives you energy on race day.
  • Drink plenty of water. In fact you should start hydrated for the race during taper week. Monitor your urine to make sure that it’s pale to light yellow without a strong odor. This means you’re well-hydrated and ready to run.
  • Load up on nitrates. Nitrates are found in plant foods, like beets, arugula and Swiss chard. When consumed, they are converted into the potent vasodilator, nitric oxide, which increases blood flow to the heart and working muscles. It also increases the efficiency by which our muscles produce energy from oxygen. This means you’ll be able to race faster and longer.

Night Before Race Day

  • Your last dinner before race morning should be planned well in advance. You want to eat an early high-carb, low-fat meal to ensure your body has enough time to fully digest everything. Dine on something you know you can handle so you don’t wake up race morning with an upset stomach. And don’t try anything new!
  • Avoid a late dinner. You don’t want that food sitting in your stomach come race morning.
  • Foods to skip: spicy foods, high-fat foods, deep-fried foods, and highly acidic foods, like tomatoes, chocolate and mint.
  • Consume foods low in fiber to prevent diarrhea, intestinal cramping and bloating. For example, choose regular spaghetti instead of whole-grain spaghetti. If you get hungry before bedtime, go ahead and snack on some high-carb foods, like bananas or dates.

Race Morning

  • The biggest rule of thumb for race-day nutrition is: don’t try anything new (again)!
  • Eat a breakfast that you have eaten several times in the past before a big run. You don’t want to test your stomach and have an emergency mid-race bathroom stop.
  • If you normally consume coffee in the morning, then do so on race day. Hot tea or coffee can help clean out your bowels before the start, which can help settle any race-day nerves.
  • About 2 to 3 hours before the race, drink 1.5 to 2.5 cups of fluids. This will ensure you’re hydrated—especially for races that start later in the morning, like Boston.
  • To top off your energy stores, you can consume 15 to 20 grams of carbs within 30 minutes of the start. Fuel on gels, chews or sports drinks—just make sure it’s the kind you’ve been training with for the past month to avoid any stomach issues.
