The Cyclist’s Fuelling Strategy: What to Eat Before and During Your Ride
Cycling
Every cyclist has a story about the "hunger flat". One moment you’re holding a steady tempo; the next, your legs turn to lead, your vision narrows and the remaining five miles home feel like a traverse across the Alps. This is "bonking", the physiological result of glycogen depletion.
Successful riding isn't just about your FTP or your training volume. It’s built on two pillars: the pre-ride foundation and the during-ride strategy.
Whether you are prepping for a local club run or a gruelling century, this guide provides the expert-backed maths to ensure you never run out of energy again.

Your pre-ride meal is about topping up the "petrol tank" (your liver and muscle glycogen) without overloading your digestive system and causing mid-ride discomfort.
The 2-3 Hour Rule
For a substantial meal, aim to eat 2–3 hours before you clip in. This allows your insulin levels to stabilise and prevents the sluggish feeling of a full stomach. Focus on low-glycemic-index (GI) complex carbohydrates that provide a slow, sustained release of energy.
- Top Picks: Porridge with fruit, white pasta or an OTE Anytime Bar.
- The 30-Minute Top-Up: If you’re riding first thing in the morning or feel a slight hunger pang before the start, have a small hit of simple carbs 30 minutes before. A banana or an OTE energy chew is perfect for an immediate glucose boost.
Pre-Hydration
Don't wait until you're thirsty. Start your ride with an electrolyte balance already established. Drinking 500ml of water with a Hydro Tab an hour before you start ensures you aren't playing catch-up with your hydration from the first pedal stroke.
