Electrolytes for trail running

Electrolytes are essential for anyone who runs long distances or trains in the heat. You lose important minerals such as sodium, potassium, and magnesium while sweating. By replenishing these, you maintain better performance and prevent complaints such as cramps or fatigue.

What are electrolytes?

Electrolytes are minerals that help your body regulate fluid balance and muscle function. The most important electrolytes for athletes are:

  • Sodium
  • Potassium
  • Magnesium
  • Calcium

During intense exertion, you lose these through sweat. Drinking only water is often not sufficient to allow your body to function optimally.

When do you use electrolytes?

Electrolytes are especially important for:

  • Long trail runs (from ±60–90 minutes)
  • Warm or humid conditions
  • High sweat production
  • Ultratrails and multi-day hikes

They help you stay hydrated and support your muscles during prolonged exertion.

What do you look for when choosing?

Not all electrolyte products are the same. Please note:

  • Compound
    Sufficient sodium is crucial – you lose the most of this through sweat.
  • Form
    Tablets, powder or capsules – choose what is practical for you
  • Added sugars
    Some products combine electrolytes with energy (carbohydrates).
  • Taste and solubility
    It is important to keep drinking enough during exercise.

Different types of electrolytes

Within this collection, you will find various options:

  • Electrolyte tablets – easy to dissolve in your soft flask or water bottle
  • Powders – often slightly more complete and easier to dose
  • Capsules – handy during races without having to mix

Depending on your preference and type of run, choose the variant that best suits your routine.
