Long days on the bike are incredibly rewarding — but only if you fuel them properly. Whether you’re lining up for an endurance race, tackling a backcountry adventure, or settling in for a big training day, getting your nutrition right can make the difference between riding strong and simply surviving.
This guide is designed to help you understand how to fuel for 5–10 hours of riding, and how to tailor your food intake to your own body, pace, and conditions.
Once you’re riding for more than a couple of hours, your body’s stored carbohydrate (glycogen) becomes limited. Without regular refuelling, energy levels drop, concentration fades, and performance — and enjoyment — suffer.
Proper fueling helps to:
Maintain steady energy output
Support focus and decision-making
Reduce fatigue and cramping
Speed up post-ride recovery
Every rider is different, but a good general guideline for endurance riding is:
30–60g of carbohydrate per hour, increasing up to 90g per hour for harder efforts or experienced riders with a well-trained gut.
Most recreational and endurance riders will perform well within the 30–90g per hour range when fueling consistently and adjusting for conditions such as intensity, terrain, and weather
Your exact needs depend on:
Body size
Ride intensity
Terrain and elevation gain
Temperature and weather
Personal tolerance and preferences
The key is consistency — small, regular intakes are far easier to absorb than large, infrequent hits of food.
While general guidelines are useful, the most effective fueling plan is one that’s tailored to you and the ride you’re doing. Here’s how to dial it in based on the key factors that influence your energy needs:
Larger riders generally burn more energy and may sit toward the higher end of carbohydrate intake per hour, while smaller riders may need slightly less. Use the hourly carb ranges as a starting point, then adjust based on how you feel over longer rides.
Harder efforts — sustained climbs, racing, or fast group riding — rely more heavily on carbohydrates. Higher intensity usually means you’ll need to fuel more frequently and lean more on easily digestible sports nutrition.
Hilly routes and technical terrain increase energy demand, even if average speed is lower. More climbing and repeated surges often require additional fuel compared to flatter, steady rides of the same duration.
Hot or humid conditions increase fluid and electrolyte losses and can reduce appetite. In these conditions, liquid calories, gels, and electrolytes become especially important to maintain energy and hydration.
Some riders thrive on gels and drink mixes, while others prefer real food. Gut comfort, taste fatigue, and texture all matter — the best fueling plan is one you can stick to consistently without stomach issues.
The goal is to experiment in training until you find a balance that keeps your energy steady and your stomach happy.
A mix of quick energy and real food works best for most riders.
These are easy to digest and simple to carry:
Sports drink or electrolyte mix
They’re especially useful during hard efforts, climbs, or later in the ride when appetite can drop.
For longer, steadier rides, real food can help with satiety and variety:
Rice cakes or wraps
Bananas
Nut butter sachets
Many riders prefer to start with more real food early on, then transition to sports nutrition later.
Fueling isn’t just about calories. Dehydration and electrolyte imbalance can derail even the best nutrition plan.
As a rough guide:
Drink to thirst, aiming for regular sips
Include electrolytes, especially in warm conditions
Adjust intake for sweat rate and conditions
If you finish rides with salt crusts on your kit or frequent cramping, electrolytes are especially important.
Never try new foods or fueling strategies on race day. Use training rides to:
Test different products
Find your preferred carb intake
Identify what your stomach tolerates under load
Your fueling plan should feel familiar and reliable when it matters most.
If you’re preparing for a competitive endurance event and want a deeper dive into exact carbohydrate targets, race-day scheduling, and product-specific strategies, we’ve covered that in more detail in our race-focused guide:
Your Guide to ‘On the Go’ Nutrition for Endurance Races
This guide builds on the principles above and walks through how to structure your nutrition during an endurance race, including gels, chews, drinks, and timing strategies.
There’s no one-size-fits-all approach to endurance fueling. The best plan is one that suits your body, your ride, and your goals.
If you’re unsure where to start, our team is always happy to help you build a fueling strategy that keeps you riding strong from start to finish.
Ride well, fuel smart, and enjoy the journey.
