Fuel Smart, Go Far: Hydration and Nutrition Tips for Endurance Athletes

The Science Behind Endurance Fueling

Glycogen is precious; carbohydrates keep it topped off. Most endurance athletes thrive on 60–90 grams per hour, often using a glucose–fructose blend to increase absorption. Start conservative in training, track stomach comfort, then progress. Share what carb targets your gut tolerates best.

The Science Behind Endurance Fueling

While carbs drive the pace, protein protects the engine. Aim for 20–40 grams within two hours post-session, and 1.2–1.7 g/kg daily during heavy blocks. This supports repair, reduces soreness, and preserves lean mass. Tell us your favorite, convenient recovery protein source.

Hydration Fundamentals You Can Trust

Measure sweat rate by weighing yourself nude before and after a one-hour session, accounting for all fluids consumed. The difference approximates milliliters per hour. Repeat across temperatures to see trends, then set targets. What surprised you most when you finally measured instead of guessing?

Hydration Fundamentals You Can Trust

Sodium needs vary widely, but many athletes target 300–800 mg per hour in heat, adjusted for sweat saltiness. Potassium, magnesium, and chloride matter too, though sodium dominates. Start small, assess cramping and energy, and refine. Which electrolyte strategy kept you steady when conditions turned brutal?

Timing: Before, During, After

Two to three hours before, many athletes do well with 1–4 g/kg carbohydrates, moderate protein, low fiber, and low fat. A small top-up snack 15–30 minutes before can settle nerves. Practice repeatedly so race-day breakfast feels boring—in the best possible way.

Maya’s Negative Split, Powered by Sips

Maya stopped chugging at aid stations and switched to small, frequent sips every kilometer tied to her watch buzz. She maintained even energy, avoided side stitches, and closed her marathon with a confident negative split. Tell us how you pace fluids without breaking stride or focus.

Luis Learns to Salt Smart

A salty-crusted cap after hot ultras finally pushed Luis to test sweat sodium. He added measured sodium capsules, spaced every thirty minutes, plus a slightly stronger bottle. No cramps, steadier mood, and fewer bathroom stops. What electrolyte change made the biggest difference on sweltering days?

Chen’s Gel Experiment

Chen trained her gut from 30 to 80 grams carbs per hour using mixed sources and a stricter fueling clock. Early discomfort faded by week four. She PR’d her half-Iron run with even splits and zero nausea. Share your progression plan for building tolerance without overdoing it.

Train Your Gut, Not Just Your Legs

Increase intake gradually across long workouts, for example from 30 to 60, then toward 90 grams per hour, using glucose and fructose to boost absorption. Track flavor fatigue, sweetness tolerance, and texture. What week-to-week increments helped you adapt without derailing quality sessions?

Train Your Gut, Not Just Your Legs

Some athletes benefit from reducing high-FODMAP and high-fiber foods 24–48 hours pre-race to minimize gut distress. Choose familiar, low-residue carbs and straightforward proteins. Practice this taper before key events. Which simple, repeatable pre-race meals keep your stomach calm and your legs lively?

Weather, Altitude, and Special Conditions

High heat drives sweat rates up and appetite down. Many athletes bump sodium toward 300–800 mg per hour and prioritize cooling with ice, sponges, or shaded aid stations. Practice heat sessions early. Which hot-weather trick has saved your day when the sun refused to quit?
