Key takeaway: Targeted sodium supplementation of 300 to 500 mg per hour stabilizes nerve transmission despite heavy sweat losses. Magnesium supports metabolism, and an adequate mineral intake protects your muscle fibers against neuromuscular fatigue. Combine a precise dosing strategy with proper hydration to cross the finish line strong.
Simultaneous absorption of glucose and fructose in a 2:1 ratio can improve your endurance performance by 8%. However, poor carbohydrate intake or forgetting electrolytes often turns a promising climb into gastric distress or sudden muscle failure. You’ve probably already experienced that loss of focus when your glycogen stores run out high in the mountains. This guide breaks down the criteria for choosing your trail energy gel, setting a precise dosing strategy, and making your long runs safer from the first climb to the finish.

Trail energy gels for performance
An effective strategy calls for 30 to 60 g of carbohydrates per hour to prevent hypoglycemia. Sodium and magnesium help prevent cramps, while absorption depends on the glucose-fructose ratio and proper hydration. Managing your nutrition carefully ensures a smooth transition to maintaining your muscular power on climbs.
Carbohydrate intake and maintaining intensity
Carbohydrates are the main fuel for your muscles in motion: they keep your blood sugar stable and help you avoid the dreaded wall every trail runner fears. Your glycogen stores run out quickly on technical trails, and gels provide readily available energy to help you maintain a steady pace. Remember to dilute this intake with a suitable soft flask: proper hydration makes sugar absorption much easier during exercise. Regular fueling ensures you perform effectively and stay alert despite the miles piling up.
Electrolytes and mineral balance while running
Sweating expels minerals such as sodium: without replenishing them, your risk of dehydration quickly increases. Enriched gels help maintain this essential osmotic balance, while magnesium actively supports muscle fiber contraction and prevents debilitating cramps. To optimize your endurance, check that your products contain these elements:
- Sodium for optimal hydration.
- Magnesium for muscle function.
- Potassium for nerve impulse transmission.
- Calcium for structural strength.
Any deficiency immediately reduces your strength. Choose complete products to take on the moors and cliffs with confidence.
Fuel selection criteria
Before you load your pockets, understand that not all sugars are equal when it comes to your gut. Your performance directly depends on the internal chemistry triggered by your fueling strategy.
Balancing glucose and fructose
A 2:1 glucose-to-fructose ratio is often ideal: it uses several intestinal transporters simultaneously, allowing you to absorb more energy without overloading your digestive system. Maltodextrin provides a more gradual release of energy, lowers the gel’s osmolarity for better tolerance, and avoids sudden insulin spikes. This helps you perform at your best for longer. Test these ratios during your specific training sessions: every trail runner has their own absorption capacity. To carry your supplies, Kinetik carrying solutions are designed for quick access during exertion.
How texture affects absorption
Liquid textures go down effortlessly on steep climbs and require less work from your stomach, making them faster to absorb than very viscous gels. Denser gels can sometimes be more filling, but they may slow gastric emptying in hot weather. Choose according to your sensitivity and the day’s weather conditions.
| Texture | Absorption speed | Digestive comfort | Recommended use |
|---|---|---|---|
| Liquid | Fast | High | Intense effort |
| Semi-liquid | Average | Medium | Endurance |
| Gelatinous | Slow | Variable | Ultra |
Viscosity directly affects your comfort while running. A texture that’s too thick can become unpleasant after several hours of sustained effort.
Fueling and hydration strategies
Having the best product isn’t enough. You also need to know when and how to take it to conquer the trails.
Timing and hourly dosage
Consume a gel about every 45 minutes: this regularity prevents fluctuations in your blood sugar and means you don't have to wait until you feel hungry to respond. Aim for between 40 and 60 grams of carbohydrates per hour; during an ultra-trail, this amount can vary depending on your tolerance and the gut training you've done beforehand. Adjust your intake according to elevation gain and cold, as your energy expenditure increases in difficult conditions. A hydration belt gives you quick access to your gels without breaking your stride.
Synergy with water and salts
Always take a few sips of plain water with your gel: this helps nutrients pass through the intestinal wall and dilutes the sugar concentration in your stomach. Without water, you risk osmotic overload, which often causes nausea or stomach problems. Avoid having very sugary drinks immediately alongside your gel, as the combination could overwhelm your ability to absorb them.
- Drink 200 ml of water per gel
- Alternate still water and electrolyte drinks
- Avoid combining gels with pure isotonic drinks

FAQ
Why should you consume energy gels during your trail runs?
The primary goal is to provide you with a rapid intake of carbohydrates and electrolytes to maintain your performance during prolonged efforts. These products limit the depletion of your glycogen stores and prevent sudden drops in energy or hypoglycemia out in the wilderness. An effective strategy relies on regular consumption, generally between 30 and 60 g of carbohydrates per hour, to sustain your effort. This helps keep your mind clear and gives your muscles the fuel they need to tackle the most demanding climbs.
How many carbohydrates should you consume per hour of running?
For efforts lasting less than 3 hours, aim for an intake of 30 to 60 g of carbohydrates per hour, primarily from glucose or maltodextrin. If your outing lasts longer, your needs increase to 60 to 90 g per hour, requiring a combination of sources such as a glucose-fructose ratio. We recommend adjusting these amounts according to the weather conditions and your own digestive tolerance. Nutritional training is crucial to getting your body used to absorbing these quantities without stomach discomfort.
How do you choose the gel texture best suited to your needs?
The choice depends on your sensitivity and the intensity of the effort. Liquid textures are easy to swallow on climbs and put less strain on your stomach, while gelatinous textures or hydrogels, such as Maurten’s, offer optimal absorption without necessarily requiring water right away. Some runners prefer the enjoyable taste of “compote” textures, while others want maximum fluidity to avoid any risk of difficulty swallowing. We recommend testing these options on your long runs to find out which you prefer.
Is it essential to drink water when taking an energy gel?
Yes, it is strongly recommended to take a few sips of plain water to help nutrients pass through the intestinal wall. Water dilutes the sugar concentration, reducing the risk of nausea or osmotic saturation in your stomach. One notable exception is hydrogel technology, which is designed to be absorbed more easily. For most conventional gels, drinking about 200 ml of water with each serving helps ensure comfortable digestion and maximize the energy product’s effectiveness.
Which essential minerals should you look for in the ingredients of your gels?
Sodium is the key mineral, especially in hot weather, with needs reaching 500 to 1,000 mg per hour to compensate for losses through sweat. Magnesium and potassium also help maintain mineral balance and proper nerve impulse function. Although recent research has nuanced the direct link between electrolytes and cramps, a complete mineral intake helps protect your muscle fibers during ultra-long efforts. Choose brands like TA Energy or Nduranz that include these ingredients to support your vital osmotic balance.
Which glucose-fructose ratio should you choose for optimal performance?
The traditional 2:1 ratio (glucose:fructose) allows several intestinal transporters to work simultaneously, increasing your capacity to absorb energy. Modern research is even exploring a 1:0.8 ratio to maximize carbohydrate oxidation while preserving digestive comfort. These complex blends prevent intestinal saturation and excessive insulin spikes. For a more natural alternative, honey is easy to digest thanks to its natural enzymes, which help your body absorb its sugars.
