Gravel Cycling Nutrition: What to Eat for a Gravel Race

Getting your gravel cycling nutrition right can make the difference between finishing strong and running out of energy halfway through your ride.

Long distances, rough terrain and sustained effort can make gravel riding particularly demanding – and the longer you’re on the bike, the more important your fuelling and hydration strategy becomes.

Whether you’re taking on the Dirty Reiver, another gravel race or simply heading out for a big day on the trails, here’s how to fuel your ride.

How to Fuel for a Gravel Race

Carbohydrate is an important fuel source during moderate and high-intensity cycling.

Your body stores carbohydrate as glycogen in your muscles and liver, but those stores are limited. During a long gravel ride, consuming carbohydrate as you go helps provide additional fuel to keep you moving.

The key is to start fuelling early and eat regularly, rather than waiting until you’re hungry or your energy starts to drop.

How Many Carbs Per Hour for Gravel Cycling?

Your carbohydrate requirements depend on the duration and intensity of your ride.

As a general guide:

• 1–2.5 hours: around 30–60g carbohydrate per hour
• Over 2.5 hours: around 60–90g carbohydrate per hour may be appropriate
• Long endurance events: experienced athletes may target higher carbohydrate intakes if they’ve trained their gut to tolerate them

Your ideal intake is individual, so use these numbers as a starting point rather than a rigid rule.

Most importantly, practise your gravel race nutrition during training.

What to Eat During a Gravel Race

One advantage of gravel riding is that you can carry a good variety of food.

During the earlier stages of a long event, you might prefer more substantial foods such as:

• Flapjacks or oat bars
• Rice cakes
• Bananas
• Sandwiches
• Energy bars

As the ride progresses, you may find that faster, easier-to-eat carbohydrates become more appealing.

Energy drinks, chews and Pocket Rockets can provide a convenient source of carbohydrate without having to stop or eat a large amount of food.

A mixture of sports nutrition and enjoyable real food can work particularly well for longer gravel events.

Eat Little and Often

Rather than consuming a large amount of carbohydrate in one go, try spreading your intake throughout the hour.

Eating little and often can make it easier to reach your carbohydrate target while reducing the amount of food sitting in your stomach at any one time.

If your target is 60g of carbohydrate per hour, for example, break that down into smaller portions and consume them regularly.

Set a reminder on your cycling computer or watch if you have a habit of forgetting to eat.

Fuel Before the Tough Sections

Look at the course profile before your gravel race.

If you know you’ve got a long climb or particularly demanding section coming up, don’t wait until you’re halfway up it to think about energy.

Take on some easily digested carbohydrate beforehand so you’ve got fuel available when the intensity increases.

Caffeine can also be useful later in longer events, particularly when physical and mental fatigue begins to build.

Again, don’t try something completely new on race day. Test your strategy during training first.

Hydration for Gravel Cycling

Your gravel nutrition strategy shouldn’t focus solely on food.

Long rides can result in significant fluid and electrolyte losses, particularly in warmer conditions.

How much you need to drink varies according to your sweat rate, weather, intensity and individual requirements, but approximately 400–800ml of fluid per hour can provide a useful starting point for many athletes.

Remember that you’re also losing electrolytes through your sweat, particularly sodium.

An electrolyte drink can help replace both fluid and electrolytes during longer rides.

For events with aid stations, check where you’ll be able to refill your bottles before setting off and plan accordingly.

Practise Your Gravel Race Nutrition

Don’t wait until race day to find out whether your nutrition strategy works.

Use your longer training rides to practise:

• Your pre-ride breakfast
• Carbohydrate intake per hour
• How frequently you eat
• Fluid intake
• Electrolytes
• Caffeine
• Which foods and products are easiest to consume while riding

Gradually build your carbohydrate intake and pay attention to both your energy levels and stomach comfort.

By race day, your fuelling strategy should feel as familiar as your bike setup.

VOOM Products We’d Recommend for Gravel Riding

For a long gravel ride or race, we’d recommend:

Pocket Rocket Energy Bars – 45g of carbohydrate split into four easy bites, making them ideal for regular energy top-ups while riding.

Fusion Fuel – 90g of carbohydrate per serving for longer rides where carbohydrate demands are higher.

Hydrate Rapid Electrolyte – A hypotonic electrolyte drink designed to support rapid hydration during long days on the bike.

ElectroBytes – Easy-to-carry electrolyte chews for topping up electrolytes without needing another drink.

Caffeine Kick Pocket Rocket – 45g of carbohydrate plus 175mg of caffeine, making it a useful option for the latter stages of a long gravel event when fatigue starts to set in.

Gravel Cycling Nutrition: Keep It Simple

The best gravel cycling nutrition strategy isn’t necessarily the most complicated.

Start fuelled, eat little and often, stay hydrated and practise everything in training.

Use a combination of real food and sports nutrition that you actually enjoy eating, and build your strategy around the duration and intensity of your event.

Get it right and you’ll have more energy to enjoy the trails – and more left in the legs when the toughest sections arrive.
