While carbohydrates<\/a> are often vilified in conversations around general health, most runners know they\u2019re essential for powering their training. For runners, the more important distinction when it comes to carbs isn\u2019t whether to eat them, but which to eat and when.<\/p>\n

\ud83c\udfc3\ud83c\udffb\u200d\u2640\ufe0f Learn what to eat before, during, and after your runs with the Runner\u2019s World Guide to Nutrition and Fueling<\/a>.<\/p>\n

Not all carbs work the same way, and your body uses them differently depending on the situation. The foods that deserve a regular spot on your plate for their nutritional value aren\u2019t the same ones that best support your running\u2014and understanding that carbs are not one-size-fits-all can make a real difference in your overall fueling<\/a> and performance<\/a>.<\/p>\n

Why Carb Type Matters for Runners<\/p>\n

When it comes to carb quality, it\u2019s not necessarily a matter of \u201cgood\u201d carbs versus \u201cbad\u201d carbs, but rather, matching the carb to what your body needs in the moment.<\/p>\n

Refined carbs<\/a> digest quickly, which makes them especially useful when you need fast energy before a workout or during a long run. They\u2019re also easier on your gut<\/a>, whereas foods that are high in fiber (think: whole grains) can trigger GI distress or slow down your digestion.<\/p>\n

\u201cWhen it comes to athletes right before and during their workouts, whole grains are not the optimal choice,\u201d Amanda Wagner<\/a>, RDN, a registered dietitian and certified run coach based in Chicago, previously told Runner\u2019s World<\/a>.<\/p>\n

The Best Carbs Before and During a Run <\/p>\n

Looking to grab a snack<\/a> before your run? Reach for foods like graham crackers, a white bagel, crackers, or pretzels rather than fiber-heavy choices like whole wheat toast, beans, or legumes.<\/p>\n

The same idea applies during longer runs and races. Gels and chews may not seem \u201chealthy,\u201d but they help fuel your body. \u201cThose added sugars [in gels and chews] are exactly what our body needs when we are running fast,\u201d sports dietitian Meghann Featherstun<\/a>, RD, CSSD, owner of Featherstun Nutrition<\/a>, previously told Runner\u2019s World<\/a>. \u201cIt\u2019s imperative for our performance to include those added sugars for specific runs and specific races, not only from a performance perspective, but also to keep us in a mentally sane place to help decrease our perceived exertion and also to help us recover faster after those events.\u201d<\/p>\n

When to Eat Whole Grains and Complex Carbs<\/p>\n

This doesn\u2019t mean runners should build their entire diet around refined grains and gels<\/a>. Outside of the workout window\u2014think your breakfast if you\u2019re running later in the day, or dinner hours after a midday workout\u2014whole grains and less-processed carbs are often the better choice at regular meals when you want more nutritional value.<\/p>\n

\u201cI think there\u2019s a time and a place for different types of processed foods to support our running,\u201d says Featherstun. \u201cAnd then we can look at other meals [outside of running] to make sure we\u2019re getting those whole grains<\/a> and getting that balance with the whole foods.\u201d<\/p>\n

Angie Asche, RD, CSSD, owner of Eleat Sports Nutrition<\/a> and author of Fuel Your Body, agrees. \u201cWhen talking about the general population, as well as everyday eating for athletes, reducing refined grains is a great strategy. But with runners, there are instances where refined grains are beneficial, because you want to saturate the glycogen stores in your muscles before any race or run that\u2019s longer than two hours,\u201d she previously told Runner\u2019s World<\/a>.<\/p>\n

The Bottom Line<\/p>\n

The smartest approach runners can take to carbs is eating them strategically. Prioritize refined carbs before and during your workout<\/a> because they digest quickly, deliver fast energy, and are easier on the gut. Then, embrace whole grains and other less-processed carbs in your everyday diet.<\/p>\n
