Know Your Engine: Assessments That Shape Your Fueling Strategy
Testing helps turn guesswork into confidence. VO2max suggests ceiling, but fat oxidation rate hints how much carbohydrate you must carry. Pair this with sweat rate and sodium concentration to set fluid and electrolyte targets, especially for hot courses or long climbs under radiant sun.
Training the Gut: Building Tolerance for Ultra Distances
Blend glucose and fructose sources for higher hourly intake with fewer complaints. Rotate textures: gels for climbs, chews on flats, soft solids at aid stations. Broths and soft potatoes can reset a queasy stomach. Keep flavors varied to prevent palate fatigue during overnight hours.
Training the Gut: Building Tolerance for Ultra Distances
Begin at 40–50 grams per hour on easier runs, then increase by five to ten grams weekly. Add small sips every ten to fifteen minutes instead of large boluses. Practice chewing while moving, and tie fueling to timers, not mood. Consistency transforms tolerance into quiet, reliable digestion.
Training the Gut: Building Tolerance for Ultra Distances
Simulate race stressors: heat sessions, long climbs, and surges near aid stations. Notice which products work when breathing is heavy and core temperature rises. Adjust sodium upward in heat, and reduce fiber before big simulation runs. Report your best heat-proof snack to help teammates reading along.
Carbohydrate Periodization and Daily Meals
High-Carb Days vs Low-Carb Sessions
Schedule high-carbohydrate availability before long runs, tempo climbs, and key simulations. Use lower-carb endurance sessions sparingly to nudge fat-oxidation without compromising quality. Always protect hard days with enough fuel to hit targets. Flex these levers around your life stress and sleep, not just the training spreadsheet.
Protein and Micronutrients for Ultra Runners
Aim for roughly 1.6–2.0 grams of protein per kilogram daily, spread across meals. Prioritize iron, vitamin D, calcium, and B12 if plant-based. Colorful produce safeguards antioxidants without megadosing. Strategic omega-3s can support recovery. Share your pantry staples—we love new ideas that make consistency effortless.
Race-Day Execution: Aid Stations, Drop Bags, and Pacing by Fuel
Anchor the plan to carbs per hour, not vibes. Print hourly targets on your wrist or poles. Count empty wrappers between stations to verify intake. If a climb slows eating, catch up gently on descents. Data-based pacing keeps energy steady when excitement, fear, or weather complicate decisions.
Race-Day Execution: Aid Stations, Drop Bags, and Pacing by Fuel
Duplicate essentials: spare soft flasks, favorite gels, salt tabs, and a savory option. Add a comfort wildcard—a fresh buff or peppermint gum—to reset your mood. Color-code bags for day versus night. Include a backup caffeine source. Comment with your smartest drop-bag hack to help fellow racers.
Plant-Forward Ultra Fueling Without GI Compromise
Vegan athletes can reach 80–100 grams per hour using mixed-carb drinks, rice-based bars, maple gels, and salted potatoes. Fortify daily meals with legumes prepared low-FODMAP and protein from tofu, tempeh, or seitan. Mind B12 and iron. Share your most reliable plant-based fuel during long climbs.
Low-FODMAP Strategies for Sensitive Runners
Audit ingredients for fructans and polyols that trigger symptoms. Choose glucose-fructose blends that stay below your personal tolerance, and emphasize lower-fiber options close to race time. Trial portion sizes precisely. Keep a symptom scale in your log. Post a product list that consistently treats your gut kindly.
Caffeine Dosing and Timing for the Overnight Hours
Use 1–3 mg per kilogram spread across the night to maintain alertness without jitters. Start later rather than earlier to preserve sensitivity. Rotate sources—gels, chews, or cola at aid stations. Hydrate alongside caffeine. What timing window keeps you sharp yet steady? Share to help the community.
Stories From the Course: Two Athletes, Two Customized Plans
Maya’s sweat sodium tested high, so she aimed for 800 mg per liter and 90 grams of carbs per hour from a cold mix and salted chews. When gels felt too sweet at noon, she pivoted to icy broth and potatoes, salvaging pace through the exposed canyon.
Stories From the Course: Two Athletes, Two Customized Plans
Long climbs crushed Jorge’s appetite, so he front-loaded carbs on runnable segments and switched to sips on ascents. He kept caffeine for the final night pass, then used rice balls at sunrise to calm his stomach. Precision pacing by fuel targets carried him strong to the finish.
