Isotonic drinks

A drink whose particle concentration is close to that of blood. Water passes more quickly through the intestine, which prevents a “heavy stomach” feeling. It generally contains carbohydrates (around 6%) and minerals.

For efforts lasting over an hour, especially in hot weather. It combines hydration, energy, and sodium. For very long efforts, supplement it with gels or bars.

A 500 ml bottle prepared according to the brand's recommended serving generally provides 25 to 40 g of carbohydrates. HIGH5 Energy Drink, for example, is prepared with 47 g of powder in 500 ml of water. Compare the product information to find the exact amount and add it to the amount from your gels.

Hypotonic: less concentrated than blood, absorbed very quickly, ideal before starting or in hot weather. Isotonic: a balance between hydration and energy. Hypertonic: very high in carbohydrates, to provide plenty of energy when you’re well accustomed to it.

Yes, refrigerate it the night before, but not too far in advance. Avoid leaving a sugary drink in the sun.

Choose light flavors (lemon, peach tea, red berries), which are better tolerated over time; alternate between two flavors or dilute a little more in hot weather.

Choose an isotonic drink when you need energy and hydration at the same time, and a sugar-free electrolyte drink when your carbs are already coming from gels or bars. An isotonic drink provides carbohydrates and sodium; an electrolyte drink, often made with a <a href="/en-ma/collections/electrolytes-sport">tablet</a>, provides mostly sodium and few or no calories. During a long effort in hot weather, many people alternate between the two bottles.
