Why White Potatoes Are a Great Pre-Run Carb Source
White potatoes give you fast-digesting, high-quality carbs-26 grams in a medium potato, 63 in a large russet-perfect for topping off glycogen stores 2–4 hours before your run. They’re packed with 620 mg of potassium, more than a banana, plus vitamin C and B6, all without the high fructose that causes GI distress. Their neutral pH and low fiber mean fewer stomach issues than gels or bars, and studies show potato puree delivers equal endurance performance at 120 grams of carbs per hour. Try them boiled, baked, or mashed with yogurt or salt-you’ll see why more runners are switching to real food fuel.
