Key Takeaway: Targeted sodium supplementation—at a rate of 300 to 500 mg per hour—stabilizes nerve transmission during periods of heavy sweating. Magnesium supports metabolism, and an adequate mineral intake helps protect your muscles from neuromuscular fatigue. Combine a precise dosing strategy with proper hydration to cross the finish line strong.
Consuming glucose and fructose simultaneously in a 2:1 ratio can improve your endurance performance by 8%. However, poor management of your carbohydrate intake or neglecting electrolytes often turns a promising climb into a stomach nightmare or a sudden muscle failure. You’ve probably already experienced that loss of clarity when your glycogen stores run out in the middle of a mountain run. This guide breaks down the criteria for choosing your trail running energy gel, defining a precise dosing strategy, and ensuring your long runs go smoothly from the first climb to the finish line.

The Trail Energy Gel for Peak Performance
An effective strategy involves consuming 30 to 60 grams of carbohydrates per hour to prevent hypoglycemia. Sodium and magnesium intake helps prevent cramps, while absorption depends on the glucose-to-fructose ratio and the quality of your hydration. This precise management of your nutrition ensures a smooth transition to maintaining your muscle power on climbs.
Carbohydrate Intake and Maintaining Intensity
Carbohydrates are the primary fuel for your muscles during exercise: they keep your blood sugar levels stable and help you avoid the “hitting the wall” phenomenon that every trail runner fears. Your glycogen stores deplete quickly on technical trails, and energy gels provide immediately available energy to help you maintain a steady pace. Be sure to mix this energy source with water in a suitable soft-sided water bottle: proper hydration greatly facilitates the absorption of sugars during exercise. Regular fueling ensures your efficiency and keeps your mind sharp as the kilometers pile up.
Electrolytes and Mineral Balance During a Race
Sweating causes the loss of minerals such as sodium; without replenishment, your risk of dehydration rises rapidly. Enriched gels help maintain this essential osmotic balance, while magnesium actively supports muscle contraction and prevents debilitating cramps. To optimize your endurance, check that these ingredients are listed in the composition of your products:
- Sodium for optimal hydration.
- Magnesium for muscle function.
- Potassium for nerve impulse transmission.
- Calcium for structural strength.
Any deficiency instantly reduces your strength. Choose nutrient-dense foods so you can tackle the moors and cliffs with confidence.
Fuel Selection Criteria
Before filling your pockets, understand that not all sugars are created equal when it comes to your gut. The effectiveness of your effort depends directly on the internal chemical reactions you trigger when you refuel.
Balance Between Glucose and Fructose
A 2:1 ratio of glucose to fructose is often ideal: it utilizes several intestinal transporters simultaneously, allowing you to absorb more energy without overloading your digestive system. Maltodextrin provides a more gradual release of energy, reduces the gel’s osmolarity for better tolerance, and prevents sharp spikes in insulin levels. This helps you maintain your performance for longer. Test these dosages during your specific training sessions: every trail runner has their own unique absorption capacity. To carry your energy reserves, Kinetik ’s carrying solutions are designed for quick access during intense effort.
Impact of Texture on Absorption
Liquid textures go down easily even when you’re climbing and are easier on your stomach, which allows for faster absorption than with a very thick consistency. Thicker gels may be more filling, but they can slow gastric emptying in hot weather. Choose based on how your body responds and the day’s weather conditions.
| Texture | Absorption Rate | Digestive Comfort | Recommended Use |
|---|---|---|---|
| Liquid | Fast | High | Intense effort |
| Semi-liquid | Average | Medium | Endurance |
| Gelatin Machine | Lente | Variable | Ultra |
Viscosity directly affects your comfort while running. A texture that's too thick can become unpleasant after several hours of sustained effort.
Nutrition 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.
Frequency of administration and dosage per hour
Consume a gel about every 45 minutes: this consistent intake prevents fluctuations in your blood sugar levels and keeps you from waiting until you feel hungry to take action. Aim for between 40 and 60 grams of carbohydrates per hour; on an ultra-trail, this requirement may vary depending on your tolerance and the digestive training you’ve done beforehand. Adjust your intake based on elevation gain and cold temperatures, as your energy expenditure increases in challenging conditions. A hydration belt gives you quick access to your gels without breaking your stride.
Synergy with Water and Salts
Always drink 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 saturation, which often causes nausea or stomach upset. Avoid drinking beverages that are too sugary immediately after taking the gel, as the combined effect could overwhelm your body’s ability to absorb nutrients.
- Drink 200 ml of water per gel
- Alternate between plain water and an electrolyte drink
- Avoid mixing the gel with pure isotonic drink

FAQ
Why should you consume energy gels during your trail runs?
The primary goal is to provide you with a quick supply of carbohydrates and electrolytes to maintain your performance during prolonged exercise. These products help limit glycogen depletion and prevent sudden drops in energy or hypoglycemia while you're out in nature. An effective strategy involves regular intake—typically between 30 and 60 g of carbohydrates per hour—to ensure you can sustain your effort. This keeps your mind sharp and provides your muscles with the fuel they need to tackle even the most challenging climbs.
How many carbohydrates should you consume per hour of running?
For activities 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 workout lasts longer than that, 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 based on weather conditions and your own digestive tolerance. Nutritional training is crucial for helping your body get used to processing these amounts without stomach discomfort.
How do you choose the gel texture that's best suited to your practice?
The choice depends on your personal preference and the intensity of your workout. Liquid textures are easy to swallow while climbing and put less strain on the stomach, while gel-like or hydrogel textures—such as those from Maurten—offer optimal absorption without necessarily requiring immediate water intake. Some runners prefer the comfort of “compote” textures for their taste, while others seek absolute fluidity to avoid any risk of difficulty swallowing. We recommend testing these options during your long runs to determine your personal preference.
Is it essential to drink water when taking an energy gel?
Yes, it is strongly recommended to take a few sips of plain water with the supplement to help the nutrients pass through the intestinal wall. Water dilutes the sugar concentration, thereby reducing the risk of nausea or osmotic overload 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 per serving ensures smooth digestion and optimizes the energy efficiency of the product.
What are the essential minerals to look for in the ingredients of your gels?
Sodium is the most important mineral, especially in hot weather, with requirements that can reach 500 to 1,000 mg per hour to compensate for losses due to sweating. Magnesium and potassium also play a role in maintaining mineral balance and ensuring proper nerve impulse function. Although recent research has qualified the direct link between electrolytes and cramps, a comprehensive mineral intake helps protect your muscle fibers during ultra-long workouts. Opt for brands like TA Energy or Nduranz, which incorporate these active ingredients to support your vital osmotic balance.
What glucose-to-fructose ratio is best for optimal performance?
The traditional 2:1 ratio (glucose:fructose) allows for the simultaneous use of multiple intestinal transporters, thereby increasing your ability to absorb energy. Modern research is even moving toward a 1:0.8 ratio to maximize carbohydrate oxidation while maintaining digestive comfort. These complex blends prevent intestinal overload and avoid sharp spikes in insulin levels. For a more natural alternative, honey is an easily digestible option thanks to its natural enzymes, which help your body absorb its sugars.
