Have you ever felt those painful cramps in the middle of a race, or that sudden fatigue that inexplicably slows you down? In endurance sports, electrolyte drinks have become indispensable for pushing back those limits. They're not just a trend, but a real revolution in terms of optimising your performance.
I still remember my first 30 km race where, having only taken water with me, I suffered terrible cramps at the 25th kilometre - a mistake I've never made again!

What are electrolytes?
Electrolytes are essential mineral salts circulating in your blood. They mainly comprise sodium, potassium, calcium and magnesium. These precious minerals play a crucial role in the optimal functioning of your body, particularly during physical exertion.
"When we sweat, we lose not only water but also these precious minerals, which can have a negative effect on our sporting performance if these losses are not compensated for.
Think of electrolytes as the sparks that allow your muscles to contract and your nervous system to transmit its signals. Without them, your body becomes like a racing car without the right fuel!
Why are they so important for sportspeople?
Perspiration isn't just water - it takes your precious electrolytes with it. An electrolyte imbalance can lead to symptoms such as muscle cramps, fatigue, dizziness and even, in serious cases, heart rhythm problems.
Electrolyte drinks are specifically formulated to replace these lost minerals. Unlike pure water, they provide more effective hydration by promoting fluid absorption and maintaining your body's electrolyte balance.
I met an ultratrailer who swears that switching to electrolyte drinks has reduced his problems with cramps during 70% 100 km races. It's the difference between giving up and crossing the finish line! 💪
The different types of sports drinks
Not all sports drinks are the same, even if they may seem similar at first glance. Here are the main categories you need to know about:
- Pure electrolyte drinks Focused on replacing mineral salts, often with little or no calories.
- Isotonic drinks Contains concentrations of sugar and salt similar to those in blood plasma, allowing rapid absorption.
- Exercise drinks Carbohydrates: Provide not only electrolytes but also carbohydrates and sometimes other ingredients such as amino acids or caffeine.
- Energy drinks Richer in carbohydrates for a significant energy intake.
During a recent marathon in Paris, I observed the diversity of choices among elite runners: some opted for light electrolyte solutions while others preferred more complete formulas with carbohydrates. The choice really depends on your body and the effort you're planning!
When and how to consume your electrolyte drinks
The drinking strategy is just as important as the choice of drink itself. To optimise your performance, follow this three-stage plan:
Before the race
Preventive hydration prepares your body for the effort ahead. Drink around 50 cl in the two hours before you set off. This preparation becomes crucial as soon as you envisage an effort lasting more than an hour.
"Before you set off on your run and set foot on the start line, remember to hydrate properly with electrolyte drinks.
During the race 🏃♂️
For efforts in excess of 1h30, it is unthinkable not to hydrate throughout the run. Take a few sips (around 150 ml) every 15 to 20 minutes. This regularity is the key!
The ideal amount varies according to the intensity of your effort, the outside temperature, your personal physiology and how you feel. The important thing is to maintain constant hydration without overloading your stomach.
A runner at my club has developed a technique of her own: she programmes her GPS to remind her to drink every 15 minutes, so she doesn't forget to drink and become dehydrated!
After the race
Recovery begins as soon as you cross the finish line. Continue to consume your electrolyte drink to quickly restore your body's equilibrium. This often neglected phase makes a huge difference to your recovery.
For short efforts (less than an hour) and in temperate conditions, water alone may suffice. However, as soon as the effort exceeds 1 hour and particularly in hot weather, electrolytes become your best ally.
The best electrolytes
The choice of electrolyte drinks is vast, but some products stand out for their quality and effectiveness:
For purists: calorie-free electrolyte drinks
The best-performing options in this category are :
- Overstims electrolyte drink
- Pure electrolytes by Nutripure
These formulations focus on the essentials: replacing exactly what you lose through perspiration, with no extra calories.
For prolonged efforts: complete formulas
Apurna long-distance drink stands out for its optimal dosage of all the components needed for endurance effort. Its only weakness is its unnatural list of ingredients.
Hydrixir Ultra by Overstims offers excellent quality at an above-average price. As with Apurna, its formulation is perfectly balanced for endurance efforts.
A triathlete friend of mine told me that he systematically tested these two products during his training sessions and gained 12 minutes on his half-Ironman time after finding the formula that suited him perfectly!
The best electrolytes value for money
Iso + from Aptonia (Decathlon) stands out for its excellent value for money. This drink has a good overall dose, with only a slightly perfectible amount of sugar and a slightly low sodium level. Its main advantage? One of the lowest prices on the market!
Conclusion: find your winning formula
Electrolyte drinks are a crucial part of your sports nutrition, particularly for endurance efforts. Choosing the right formulation can really transform your experience and performance.
Test different options during your training sessions before using them in competition. Your body is unique and will react differently from other athletes - it's up to you to find out what works best for you!
Are you ready to push yourself to the limit with optimised hydration? The difference between a good performance and an excellent one is sometimes hidden in these details that champions never neglect. 🏆
