Sweet Potato with Freshly Grated Parmesan (Calories: 150)
Sweet potatoes are an easily digestible carb and a great source of fiber, which helps you feel fuller than you would after eating the same amount of, say, white rice, says Koszyk. If you suffer from GI issues, you can shave a gram of fiber by tossing the potato skin. Even without the skins, these spuds are nutritional workhorses, boasting vitamins A, C and B6 and almost as much potassium per cup as a banana. Potassium is an electrolyte that helps stave off fatigue and muscle cramps during a run.

Open-Faced Smoked Turkey Sandwich (Calories: 170)
Koszyk views this streamlined lunch staple as a go-to choice for avoiding a mid-morning pre-run pastry or a midday cookie. Here, flavorful smoked turkey and mashed avocado eliminate the need for less nutritious, high-calorie condiments like mayo or aioli. The avocado also contains potassium, which aids muscle function. If you can't find smoked turkey, opt for fresh roasted turkey or chicken instead of fattier lunch meats like salami or bologna.

Buckwheat Soba Noodles with Chicken (Calories: 240)
Buckwheat soba noodles are slightly higher in carbs than pasta but with a nutty, earthy flavor. And if the noodles are made with 100 percent buckwheat flour, they're also gluten-free. The sesame seeds provide 7 percent of the recommended daily value of iron per 1-tablespoon serving, a hard-to-get nutrient that can leave runners fatigued if their levels become too low.
