Start With You: Mapping Your Endurance Fuel Profile

Log weekly volume, intensity distribution, terrain, and weather, plus body weight trends and mood. These anchors make nutrition changes measurable, preventing random tweaks from misleading you. Share your baseline in the comments so we can compare notes thoughtfully.

Test sweat rate by weighing before and after a steady session, tracking fluid intake and urine. Expect seasonal changes. Begin daily hydration near 30–35 ml per kilogram, then adjust with data, not guesswork. Post your latest sweat test to inspire others.

Watch for persistent fatigue, sleep changes, irritability, or unusually hard easy days. These can signal low energy availability. A weekly reflection—how you felt, performed, and recovered—keeps your fueling honest. Comment your top recovery win this week.

Smart Carbs: Precision Fueling for Long Efforts

Two to three hours before key sessions, aim for a carb-forward meal with modest protein, low fiber, and minimal fat. A small top-up 15–30 minutes pre-start can sharpen energy. Share your favorite calm-stomach pre-workout meal with our community.

Smart Carbs: Precision Fueling for Long Efforts

Target 30–60 g carbs per hour for steady efforts, up to 90 g with glucose–fructose blends at higher intensities. Practice delivery every week to train absorption. Tell us how your gut handled 60 g per hour versus 80 g during recent long runs.

Smart Carbs: Precision Fueling for Long Efforts

Within 30–60 minutes, rebuild with 1.0–1.2 g carbs per kilogram, then continue steady carbs for a few hours. Anecdote: Maya finally cracked back-to-back sessions after tightening this window. What post-workout snack actually makes you feel human again?

Protein for Endurance: Repair, Adaptation, and Staying Durable

Aim for roughly 1.4–1.8 g protein per kilogram daily, split into 3–5 feedings. Hit 20–40 g per meal depending on body size. Consistency, not perfection, wins. Drop your favorite high-protein go-to that travels well on training days.

Protein for Endurance: Repair, Adaptation, and Staying Durable

Each feeding should deliver about 2–3 g leucine to switch on muscle protein synthesis—whey, dairy, eggs, or balanced plant blends help. One athlete cut soreness dramatically by finally spacing protein across the day. Try it and report back.

Hydration and Electrolytes: Keeping Pace With Your Environment

Sodium: The Often-Missing Variable

Many endurance athletes thrive between 300–800 mg sodium per hour in heat, though needs vary widely. Story: When Jonah matched intake to humid conditions, his late-race surges returned. What conditions challenge you most? Let’s troubleshoot together.

Practical Hydration Planning

Translate sweat test results into bottle plans and refill points. Consider cooler fluids, easy-open caps, and saltier mixes for long climbs. Practice during long workouts, not race day. Post your bottle setup and why it survives chaotic aid stations.

Caffeine and Heat: Handle With Care

Caffeine can sharpen focus, but pair thoughtfully with fluids in heat to avoid spirals. Trial dosing in training, starting small. Share what timing keeps you alert without jitters—your insight may save someone’s toughest climb or final 10K.

Train the Gut: Comfort Under Pressure

Progressive Carb Tolerance

Start at the low end of your hourly carb range and rise weekly, holding steady if discomfort appears. Mix sources—drink, chews, and soft foods—to distribute load. Report your latest successful combo so others can test similar blends.

Fiber Timing and Pre-Race Calm

Shift higher-fiber foods earlier in the day before long sessions, tapering closer to go-time. Low-FODMAP swaps can help sensitive guts. Comment with your pre-race dinner that keeps you confident yet comfortably fueled through the starting chute.

Troubleshooting GI Distress

If cramps or sloshing appear, reduce intensity briefly, sip steadily, and ease concentration. Reassess sodium and carb mix afterward. Share what fixed your worst mid-race stomach episode—your hard-won lesson might spare someone else the detour.

Race Week and Day: A Plan You’ve Practiced

Strategically increase carbs 2–3 days prior while moderating fiber and fat. Aim near 7–10 g per kilogram for long events if tolerated. Tell us your favorite simple carb-load staples that leave you energized, not heavy or restless.

Race Week and Day: A Plan You’ve Practiced

Eat a familiar breakfast 2–3 hours pre-start, plus a small top-up closer to go-time. Confirm caffeine, fluids, and bathroom timing. Drop your race morning ritual—music, mantra, or meal—that flips nerves into focused readiness.
