Cycling Nutrition Guide: What to Eat Before, During and After Every Ride
Cycling nutrition is the practice of fuelling your body with the right foods and fluids at the right times to sustain performance, delay fatigue, and accelerate recovery during and after bike rides. Poor nutrition on the bike has one well-documented consequence: “bonking” — the sudden, severe energy depletion that occurs when muscle glycogen runs out. It is entirely preventable with proper fuelling.
Key Takeaways
- Carbohydrates are the primary fuel for cycling — aim for 30–60g per hour on rides over 60 minutes
- Hydration strategy: 500–750ml of fluid per hour, more in heat or at high intensity
- Electrolytes — especially sodium — are as important as water for performance and safety
- Never try new nutrition on race or event day; train your gut like you train your legs
- Recovery window: eat a 3:1 carbohydrate-to-protein meal within 45 minutes of finishing
Before Your Ride: Pre-Ride Nutrition
For rides under 60 minutes: Your existing glycogen stores are sufficient. A normal meal 2–3 hours beforehand is all you need.
For rides 1–3 hours: Eat a carbohydrate-rich meal 2–3 hours before. Aim for 1–2g of carbohydrates per kilogram of bodyweight — a bowl of oatmeal with banana and honey, or rice with chicken and vegetables.
Top Pre-Ride Foods: Porridge/oatmeal with banana and honey, toast with peanut butter and banana, rice with eggs and lean protein, smoothie with oats and nut butter.
During Your Ride: On-Bike Fuelling
| Ride Duration | Carbs Per Hour | Strategy |
|---|---|---|
| Under 60 min | 0g | Water only is sufficient |
| 60–90 min | 30g | Single carb source |
| 90 min–3 hours | 60g | Mix of glucose and fructose |
| Over 3 hours | 80–100g+ | Multiple transportable carbs |
Hydration During Riding
Aim for 500–750ml of fluid per hour in cool conditions, increasing to 750–1,000ml in heat above 28°C. Target 600–1,000mg of sodium per litre of fluid during rides exceeding 90 minutes or in heat.
After Your Ride: Recovery Nutrition
Target a 3:1 ratio of carbohydrates to protein within 45 minutes of finishing:
- Carbohydrates: 1–1.2g per kg of bodyweight
- Protein: 20–30g to stimulate muscle repair
- Fluid: 1.5L for every kilogram of bodyweight lost
Best Recovery Foods: Chocolate milk, Greek yogurt with granola and fruit, rice with grilled chicken, smoothie with banana and protein powder.
Frequently Asked Questions
How many calories do cyclists burn per hour?
A 70kg rider cycling at 25 km/h burns approximately 450–550 calories per hour. Climbing or higher intensity increases this to 700–900 calories per hour.
What should I eat the night before a long ride?
Eat a familiar, carbohydrate-rich meal: pasta, rice, or potatoes with lean protein and low-fibre vegetables. Avoid high-fat, high-fibre, or very spicy foods.
Are energy gels necessary for cycling?
No — a banana, dates, or rice cakes provide comparable carbohydrate content. Gels are convenient but not nutritionally unique.
Should I eat during a 1-hour ride?
For moderate intensity, eating on the bike is generally unnecessary if you’re well-fuelled beforehand. At high intensity, consuming 30g of carbohydrates around the 45-minute mark helps.
What causes cramps in cyclists?
The most common cause is a combination of muscle fatigue and electrolyte depletion — particularly sodium. Staying well-hydrated and maintaining sodium intake during long rides reduces cramp risk.
