What Carbohydrate Loading Really Means
Carbohydrate loading is not everyday eating; it is a focused, short-term strategy that elevates glycogen stores before a key event. Think purposeful, planned, and timed—like sharpening a knife rather than swinging it harder.
What Carbohydrate Loading Really Means
Your muscles store glycogen for power; your liver keeps blood glucose steady when pace and nerves rise. Loading tops off both tanks, reducing the risk of late-race fade and reactive fueling decisions.
What Carbohydrate Loading Really Means
Long-duration events drain glycogen steadily, which is why marathoners, triathletes, cyclists, and ultra-runners see the biggest payoff. Sprinters typically do not need loading, but endurance athletes gain precious minutes and resilience.
Each gram of glycogen binds water, so expect a gentle weight uptick during loading. It is performance weight, not bloat; that water helps thermoregulation, muscle function, and maintaining power when the race stretches long.
Science of Glycogen and Performance
Proven Loading Protocols and Timelines
Cut training volume, raise carbohydrate percentage, and spread meals across three days. Include easy-to-digest starches, modest protein, and small portions of fat. Track how you feel and share your notes with us for feedback.
Menu Building: Real Foods and Practical Portions
White rice, pasta, potatoes, sourdough, tortillas, oats, bananas, and rice cakes are reliable. Add a drizzle of maple syrup or honey and a pinch of salt. Share your favorite combinations so others can discover tasty options.

Race-Day Execution and Morning-of Details
Eat a familiar, carb-forward breakfast three to four hours before the start. Keep fiber low, protein moderate, and fluids steady. If nerves cut appetite, go smaller but sip a carb drink to bridge the gap.
Race-Day Execution and Morning-of Details
Plan a fueling rhythm by time rather than mood. Start early, before you feel empty. Align gel flavors with aid station water, and rehearse carrying backups. Comment with your timing plan for community feedback.
Mistakes, Myths, and Fixes
Loading means higher carbohydrate percentage, not uncomfortable volume. Choose denser carbs, eat more often, and keep portions reasonable. Feeling light and ready beats waddling to the start with an overstuffed stomach.
Mistakes, Myths, and Fixes
A small weight uptick is a sign loading worked. Water bound to glycogen supports endurance. Focus on feel and pacing, not temporary numbers. Share your before-and-after impressions so others can reframe their expectations.
Mistakes, Myths, and Fixes
Elite protocols reflect unique physiology, staff support, and race demands. Borrow principles, not exact menus. Customize to your gut, schedule, and climate. Post your personalized plan so we can help refine it together.
Field Notes: A Marathoner’s Carb-Load Story
From Hitting the Wall to Hitting the Pace
Maya bonked at mile twenty-two last year. This time she trimmed fiber, spread carbs across three days, and added sodium. She wrote each meal down, stayed calm, and never felt that hollow, sinking feeling.
Nerves, Breakfast, and a Simple Plan
Race morning, nerves muted her appetite. She sipped a light carb drink, ate a small bagel with honey, and started fueling at twenty minutes. The clock felt slower; her stride felt easier.
