MOUNTAIN BIKING NUTRITION TIPS - HOW TO FUEL FOR CONSISTENT PERFORMANCE
Mountain biking places unique physiological demands on the body, with each discipline bringing its own challenges. Whether it’s the gruelling high-intensity efforts of cross country racing, the repeated descents and transitions of enduro MTB or long days out on the trails, riders are constantly switching between steady efforts and explosive bursts of power.
Across all formats, mountain biking requires a combination of endurance, strength, focus and bike skills. Riders must handle steep climbs, technical terrain and fast descents, all while maintaining control and making split second decisions.
Sessions can range from short, intense races to full day adventures. Throughout this time your body is working continuously, burning energy, losing fluids and relying heavily on carbohydrate availability.
This combination of sustained effort and intensity leads to rapid glycogen depletion, increased carbohydrate usage and ongoing electrolyte loss through sweating.
Without a structured fuelling approach, riders may experience :
- A noticeable drop in energy levels
- Reduced power output
- Cognitive decline & lower reaction times
- Increased muscle fatigue and risk of cramping
UNDERSTANDING MTB ENERGY DEMANDS
Carbohydrates are the body’s primary fuel source during mountain biking disciplines, particularly at moderate to high intensities across long durations.
Carbohydrates are stored as glycogen in the muscle and liver :
- Approximately 400–500 g in muscle
- Around 80–100 g in the liver
These stores are limited and can be depleted quickly during longer or more demanding rides.
Carbohydrate use typically ranges from 40-90 g per hour depending on intensity and rider size.
When glycogen stores are low the body then relies more heavily on the oxidation of fat stores to generate energy. However fatty acids are a much more slowly released energy store, hence the onset of fatigue when training at high exercise intensities with depleted glycogen levels
For rides exceeding 90 minutes, consistent fuelling becomes essential to maintain performance.
PRE-RIDE NUTRITION
Starting your ride properly fuelled sets the foundation for everything that follows.
In the 36–48 Hours Before
For longer or more intense rides, increasing carbohydrate intake ahead of time can help maximise glycogen storage.
PRE-RIDE
Consume a carbohydrate-focused meal 1–4 hours before riding :
- 1–4 g of carbohydrates per kg of body weight
- Focus on lower GI carbohydrate sources (legumes, pulses, grains & cereals)
- Keep fat and fibre relatively low for easier digestion
This supports a steady release of energy without sudden spikes or drops.
Hydration should also be addressed before you start.
- Avoid Excessive water intake. Sodium concentrations can become diluted to a deadly level causing hyponatremia (essentially drowning the body).
- Slowly consume 5-10 ml per kg of body mass of an electrolyte rich drink 2-4 hours prior to exercise (We recommend our Hydro Fizz Electrolyte Range)
- Check your urine colour to measure hydration status (aim for a very slight pale yellow).
FUELLING DURING YOUR RIDE
Once you’re on the bike, the aim is to maintain energy levels consistently.
A general guideline :
40-60 g of carbohydrates per hour
Higher amounts may be beneficial during more intense efforts if tolerated, for more information on training the gut read our blog
Fast digesting carbohydrates (high GI) are particularly useful during riding, as they provide readily available energy when you need it most!
PRACTICAL MTB FUELLING APPROACH
Mountain biking often limits opportunities to stop and eat, so your fuelling strategy needs to be simple, efficient and easy to execute. If not, it likely won't be executed consistently.
Eat Little and Often
Rather than consuming large amounts infrequently :
-
Aim for 20–30 g of carbohydrates every 20–30 minutes
This helps maintain stable energy levels and reduces the risk of fatigue later in the ride.
Energy Gels On The Go
On technical sections or climbs, stopping to eat isn’t always practical.
Our Intra Energy Gels provide a quick and efficient solution. They’re easy to carry and can be consumed in seconds, delivering 40g dual carbohydrate source without disrupting your rhythm on the bike.
Convenient Drink Based Carbohydrates
Carrying a bottle or hydration bladder enables riders to be able to consume '2 in 1' hydration and fuelling drinks mix powders! Sip little and often during your rides.
Our Intra Carb Mix offers a simple way to stay fuelled and hydrated. Each 500ml serving contains 40g of dual source carbohydrates with an added quad electrolyte blend, it's that simple! The single serving sachets are easy to carry and can be mixed into your bottle when topping up mid ride!
Solid Fuel for Longer More Casual Rides
For extended days out and instances where rests periods can be taken, including solid foods can help maintain energy levels whilst satisfying hunger.
The Intra Carb Bars are light, compact, easy to carry and provide 40g of fast release carbohydrates! A great addition to your pockets for a delicious mid ride stack.
HYDRATION AND ELECTROLYTES
Hydration is a key factor in maintaining performance on the bike.
As fluid levels drop :
- Heart rate increases
- Effort feels harder
- Performance declines
Sweat loss also leads to a reduction in electrolytes - particularly sodium which is essential for muscle function and fluid balance.
Riders in a dehydrated state are likely to experience :
- Increased fatigue
- Muscle cramps
- Brain fog
Maintaining regular fluid and electrolyte intake is especially important during longer rides or in warmer conditions.
KEEPING YOUR NUTRITION ACCESSIBLE
Consistency is much easier when everything you need is within reach.
The RIDE Nutrition Micro Pouch is designed to keep your ride essentials organised and easily accessible. Compact and practical, it allows you to carry small items without the parry of them getting wet!
Most mountain bike enduro events have 'hydration points' at various distances around the trail. Riders stop to refill bladders and bottles, so having the option to add a Hydro Fizz Electrolyte tablet to your drink or consume a caffeine / electrolyte capsule hours into an event can make a huge difference in performance.
It’s ideal for storing :
This makes it easy to take on electrolytes or introduce caffeine at key moments when you may be a long way from the pits / supplies.
POST-RIDE RECOVERY
After intense racing or a long day out on the bike, preparing a full meal immediately may not always be practical. A recovery shake provides a quick and efficient way to start the recovery process as you head back home.
A well designed recovery drink like the Reload Recovery Mix helps address all three ‘R’s of recovery in one shake :
- Repair with protein
- Refuel with carbohydrates
- Rehydrate with fluids and electrolytes
Our Reload Recovery Mix is a great example, created specifically with this principle in mind. Providing protein, carbohydrates and electrolytes in one drink to help kick-start recovery immediately after exercise.
Consuming a recovery shake within 20–30 minutes of finishing exercise helps take advantage of the body’s optimal recovery window, when nutrients are more readily used for glycogen replenishment and muscle repair.
