Why Carbohydrate Loading Works: The Science You Can Use
Carbohydrate loading increases glycogen stored in muscles, giving you more readily available energy during long efforts. Think of it as topping off a portable battery you can’t swap mid-race. When glycogen runs low, pace and mood typically suffer. Loading postpones that fade.
Two Proven Loading Methods: Pick What Fits Your Life
The Classic Depletion-to-Loading Week
Old school plans reduce carbs and train hard early in the week, then dramatically increase carbs with a taper. It can work, but the initial depletion phase can feel grim and isn’t necessary for most athletes. Consider this only if you’ve tested it and tolerate it well.
The Modern Taper with High-Carb Days
Most athletes thrive on a gentler approach: reduce training volume while raising carbohydrate intake. You keep regular, familiar foods, avoid the misery of depletion, and let training stress fade. The result is topped-up glycogen without mood swings, sleep disruption, or risky digestive experiments before race day.
Matching Method to Event and Personality
If you race better calm and predictable, the modern taper method usually wins. Detail-oriented athletes sometimes enjoy the structure of classic protocols. Either way, test your approach before key races to confirm energy, sleep, and digestion cooperate. Share your method in the comments to help others learn.
Daily Carb Targets by Body Mass
For most endurance athletes loading for events over ninety minutes, aim roughly seven to twelve grams of carbohydrate per kilogram body mass per day. Longer ultra efforts may require the higher end. Spread intake across meals and snacks to keep digestion comfortable and energy steady throughout the day.
Keep Fiber and Fat Moderate
To avoid race-week bloating, shift toward lower-fiber, familiar carbohydrate sources: rice, potatoes, pasta, bread, oats, rice cakes, ripe bananas, and juices. Keep fats moderate and emphasize easy proteins like yogurt or eggs, so your stomach stays calm while glycogen storage quietly rises without protest.
Hydration, Sodium, and Glycogen’s Water Buddy
Glycogen binds water, so expect scale increases of one to two kilograms during a good load. That’s a feature, not a bug. Drink consistently, include sodium with meals, and don’t chase every weigh-in fluctuation. Proper hydration helps transport carbohydrates and supports muscle readiness for long, sustained efforts.
The Clock: 72, 48, and 24 Hours Before the Start
01
Seventy-Two Hours Out: Ramp Up and Observe
Begin increasing carbohydrates while tapering volume. Keep meals familiar and note digestion, sleep, and mood. Light mobility or short strides can maintain pop without draining fuel. This is your quality-control window to adjust portions and cooking methods before the pressure of the final day.
02
Forty-Eight Hours Out: Simplify and Standardize
Lock in easy, repeatable meals. Many athletes choose rice bowls, sandwiches, pancakes, or potatoes with lean protein. Avoid novelty foods and heavy sauces. Hydrate steadily, sprinkle in electrolytes, and keep caffeine typical for you. Consistency now reduces race-eve nerves and fluke digestive issues.
03
Twenty-Four Hours Out: Low-Residue and Familiar
Focus on simple carbohydrates you know you tolerate. Portion sizes remain generous, but fiber drops further. For dinner, think rice or pasta with a light sauce and small protein. Snack lightly before bed if hungry, then start race morning with your practiced pre-race breakfast and plan.
Gut-Friendly Loading: Keep Calm and Digest On
Favor lower-fiber options and split large meals into smaller, more frequent servings. Chew thoroughly, slow the pace at dinner, and stop eating when pleasantly full. If you easily bloat, pull back on raw veggies and carbonated drinks this week to keep your digestive system peaceful.
Gut-Friendly Loading: Keep Calm and Digest On
Keep caffeine at your usual level to avoid jitters or headaches. If sensitive to fructose or FODMAPs, lean on glucose-heavy sources like rice and potatoes, and test mixed-sugar sports drinks in training. Personal tolerance rules here, so track responses and adjust your carbohydrate sources accordingly.
