How to Fuel Your Body for Long Mountain Bike Rides

Nothing ends a good ride faster than bonking two hours in — that sudden wall of exhaustion when your body runs out of accessible fuel. Getting nutrition right is as much a skill as bike handling.

Before the Ride

Eat a real meal with carbohydrates 1-3 hours before a long ride — this tops off glycogen stores you'll draw on during the effort. Avoid heavy, high-fat meals right before riding; they digest slowly and can sit uncomfortably during hard efforts.

During the Ride: The 60-90 Minute Rule

For rides under an hour, water alone is usually fine. Past that, your body needs incoming carbohydrates to sustain effort — aim for roughly 30-60 grams of carbs per hour on longer rides, through whatever's easiest to carry and digest: gels, chews, bananas, or a carb-based drink mix.

Signs you've waited too long to fuel: - Sudden, sharp drop in energy or focus - Irritability or difficulty concentrating on line choice - Legs feeling suddenly heavy despite a normal pace

By the time you feel these, you're already behind — the fix is eating on a schedule (every 30-45 minutes) rather than waiting until you feel low.

Hydration Alongside Fueling

Water alone on long, hot rides can actually dilute sodium levels if you're sweating heavily — an electrolyte mix or salt tabs on rides over 90 minutes in heat helps prevent cramping alongside straight fueling.

After the Ride

A combination of carbs and protein within about 30-60 minutes post-ride speeds up glycogen replenishment and muscle recovery — a simple example is a protein shake with a banana, or a normal meal if you're heading straight home.

Practical Trailside Options

• Gels and chews — compact, fast-digesting, easy to carry in a jersey pocket
• Bananas or dried fruit — real food option, easy on the stomach
• Carb-electrolyte drink mix — covers fueling and hydration together

Fueling well doesn't need to be complicated — the main mistake most new long-distance riders make is simply waiting too long to start eating, not choosing the wrong food.
