Nutrition for Long Cycling Tours – Energy for 4, 6 or 8 Hours in the Saddle
Long bike tours are among the most beautiful challenges in endurance sports. Proper nutrition for long bike tours is crucial for performance and endurance – whether road cycling, gravel, or bikepacking.
The right energy supply determines performance or bonking – the right products make all the difference. Sports nutrition for road cyclists can help optimize energy intake.
In this guide, you will learn:
- how many carbohydrates you need while road cycling
- what you should eat during 4, 6, or 8 hours in the saddle
- how to consume up to 100 g of carbohydrates per hour
Why nutrition is so important when road cycling
When road cycling, the body consumes enormous amounts of energy. Depending on the intensity, 500 to 900 kcal per hour can be burned.
The most important energy source is carbohydrates. However, the body's glycogen stores usually only last for about 60 to 90 minutes of intense riding. Therefore, carbohydrates must be consumed regularly during the ride.
Carbohydrates per hour when road cycling
| Duration | Carbohydrates per hour |
|---|---|
| 1–2 hours | 30–50 g |
| 2–4 hours | 50–70 g |
| 4–6 hours | 60–90 g |
| over 6 hours | 70–100 g |
Many ambitious endurance athletes even try to consume 90–100 g of carbohydrates per hour during intense exertion.
💡 Practical tip: The values mentioned are average values from sports science recommendations for endurance athletes. The actual carbohydrate requirement can vary depending on body weight, intensity, training status, and individual tolerance. Therefore, always test your nutrition strategy during training before using it in a competition.
Example Strategy: 100 g Carbohydrates per Hour
| Energy Source | Carbohydrates |
|---|---|
| HydraCarb+ Drink (ProSeries) | 60 g |
| ProSeries Gel Natural | 40 g |
Together, this amounts to 100 g of carbohydrates per hour. This strategy is often used by ambitious road cyclists and gravel athletes in competition. Suitable carbohydrate drinks, energy bars, and energy gels enable a consistent and well-tolerated energy supply.
Nutrition for Road and Gravel Races – 100 km to 300 km
The longer a race lasts, the more important a continuous energy supply becomes.
| Distance | Duration | Power | Carbohydrates per hour |
|---|---|---|---|
| 100 km | 3–4 h | 220–260+ W | 70–90 g |
| 150 km | 4–5 h | 200–240 W | 80–90 g |
| 200 km | 6–7 h | 180–220 W | 80–100 g |
| 300 km | 8–12 h | 160–200 W | 70–90 g |
Example Nutrition Strategy for Long Road Cycling Trips
| Hour | Energy Intake |
|---|---|
| 1 | HydraCarb+ Drink |
| 2 | Energy bar |
| 3 | ProSeries Gel Natural |
| 4 | HydraCarb+ Drink (optional with caffeine) |
| 5 | Energy bar |
| 6 | Gel (optional with caffeine) |
👉 Tip: Many riders rely on a combination of carbohydrate drink and gel to efficiently absorb high amounts and ease stomach discomfort.
Strategic use of caffeine for increased performance
During long bike tours and intense exertions, caffeine can significantly improve performance. It reduces perceived effort and helps maintain stable performance, especially in later race phases.
When caffeine is useful:
Caffeine should not be consumed from the start, but primarily when fatigue sets in – typically after 2 to 3 hours in the saddle.
Practical implementation in training and competition
A proven strategy is the combination of constant energy supply and targeted caffeine boosts:
- Carbohydrate drink (e.g., HydraCarb+) for a consistent energy supply
- Energy bars for longer exertions
- Caffeine gel as a targeted performance boost in the second half, e.g., Energy Gel with Caffeine
A caffeine gel is particularly effective before:
- long climbs
- intense race phases
- the last hours of a long ride
Dosage and important notes
Many athletes use a total of about 3–6 mg of caffeine per kilogram of body weight distributed throughout the entire exertion.
Important notes:
- Caffeine affects individuals differently
- Excessive amounts can cause stomach problems or nervousness
- Always test new strategies in training first
Carb Intake Cheat Sheet for Road & Gravel Riders
| Time in the saddle | Intensity | Carbohydrates per hour |
|---|---|---|
| 1–2 hours | moderate training | 30–50 g |
| 2–4 hours | intensive ride | 50–70 g |
| 4–6 hours | long training ride | 60–90 g |
| 6–8 hours | Gran Fondo / Gravel Race | 70–100 g |
| 8+ hours | Ultra / Bikepacking | 70–90 g |
Golden Rules for Road and Gravel Nutrition
- Start eating early – as early as 30–40 minutes in.
- Consume small amounts regularly instead of large portions infrequently.
- Combine drinks, bars, and gels to achieve high carb intake.
- Always test new nutrition strategies in training first.
- Drink enough, especially in the heat.
Note: The quantities mentioned serve as a guide for typical demands in road and gravel cycling. Every athlete reacts differently to carbohydrates and should test their personal nutrition strategy in training.
Conclusion
Proper energy planning often determines performance or bonking in endurance sports. Modern nutrition strategies focus on 80–100 g of carbohydrates per hour during intense exertion.
A combination of carbohydrate drinks, energy bars, and energy gels ensures a reliable energy supply for many hours in the saddle.
The optimal amount of carbohydrates is individual and depends on factors such as intensity, training status, and tolerance. The values mentioned serve as a guide and should be tested in training.
Frequently Asked Questions about Road Cycling Nutrition
How many carbohydrates per hour when road cycling?
For moderate exertion, many sports scientists recommend about 50–70 g of carbohydrates per hour. During intense training or competitions, many road cyclists try to consume 80–100 g of carbohydrates per hour to avoid performance drops.
What should you eat on long bike tours?
For long bike tours, easily digestible carbohydrate sources such as energy bars, energy gels, or carbohydrate drinks are particularly suitable. Many athletes combine solid food and liquid energy to ensure a constant energy supply.
When should you start consuming energy during a bike tour?
Many experts recommend starting the first energy intake after about 30 to 40 minutes. This keeps blood sugar levels stable and allows the body to continuously use the energy.
How many carbohydrates do you need for a Gran Fondo or long race?
For long races or Gran Fondos, many endurance athletes try to consume between 80 and 100 g of carbohydrates per hour. A combination of carbohydrate drink, energy bars, and energy gel has proven to be particularly effective.
How many carbohydrates per hour when road cycling on long rides?
In short: When road cycling, depending on the intensity, about 50–100 g of carbohydrates per hour are recommended. For long and intense rides, up to 100 g per hour can be useful, provided it is well tolerated.
