Carbohydrates: The Prime Mover of Endurance
Glycogen is your high-octane fuel for tempo runs, climbs, and surges. Most endurance athletes thrive on 5–7 g/kg carbohydrate during moderate training, and 7–10 g/kg on heavy weeks. What’s your sweet spot? Comment with your best carb-loading strategy.
Fat Utilization and Metabolic Flexibility
At lower intensities, fat oxidation spares glycogen and extends time to fatigue. Consistent aerobic base work, smart fueling, and not chronically under-eating carbs help build flexibility. Have you noticed easier long runs after steady base phases? Tell us below.
Two to four hours pre-effort, target 1–4 g/kg carbohydrate with low fiber and moderate protein. A small, familiar snack 30–60 minutes out can top up. What pre-run breakfast sits best for you? Drop a tip for our community.
Timing Your Fuel: Before, During, and After
Most athletes perform well on 30–90 grams of carbohydrate per hour, especially using multiple transportable carbs (glucose + fructose). Train your gut in practice, not on race day. What gel, chew, or rice ball strategy keeps you steady? Share your pacing routine.
Timing Your Fuel: Before, During, and After
Know Your Sweat Rate and Sodium Losses
Weigh before and after a steady session; one kilogram lost approximates one liter of sweat. Track conditions and pace. Adjust fluid and sodium accordingly. Have you tested your sweat rate? Share your number and what surprised you most.
Avoiding Hyponatremia and Overdrinking
Drinking far beyond sweat loss—especially water-only—can dilute blood sodium. Pair fluids with electrolytes, and use a plan informed by thirst, pace, and conditions. What electrolyte mix worked in heat or humidity? Post your formula and race-day tweaks.
A Heat Story: Lessons From the Road
A cyclist in Texas kept cramping late in rides until sodium testing revealed high losses. With 800–1,000 mg sodium per hour in the heat, cramps vanished and pacing smoothed. Have a breakthrough story like this? Tell us and help others adapt.
Micronutrients and Evidence-Based Ergogenics
Low ferritin can sap endurance, especially for menstruating athletes. Pair iron-rich foods with vitamin C, and avoid tea or coffee with iron-rich meals. Have you tracked ferritin through training blocks? Share what monitoring changed in your approach.
Gut Training and GI Comfort on the Move
Practice ingesting your target carbs per hour during long runs, matching gel concentration with water to manage osmolality. Test different textures and flavors. Which product sits best at race pace for you? Report back to help others refine choices.
Gut Training and GI Comfort on the Move
If sensitive, reduce fiber 24–36 hours pre-race. Favor familiar, low-fat carbs—white rice, bananas, bagels with honey. Keep portions steady. What exact pre-race meal gives you confidence? Post the details so the community can learn.
Practical Meal Planning for Endurance Weeks
Cook grains, potatoes, and legumes in bulk to assemble fast meals with colorful produce and protein. Keep snacks like dates with nut butter or rice cakes handy. What’s your simplest high-carb dinner? Comment and inspire someone’s next prep session.
Practical Meal Planning for Endurance Weeks
Prioritize B12, iron, zinc, iodine, and omega-3s; consider algae-based DHA/EPA. Combine grains and legumes, and use vitamin C to boost iron absorption. Plant-based athletes, what staples carry your long weeks? Share your list and subscribe for recipe ideas.
Practical Meal Planning for Endurance Weeks
Pack instant oats, electrolyte packets, and familiar gels. Use a hotel kettle, scout nearby groceries, and plan pre-race breakfast. What travel trick saved your fueling plan? Post your tip, and subscribe for our race-week checklist.
