Mountain sports such as trail running require not only impeccable physical preparation, but also the right, high-performance equipment. Among the essential elements of a trail runner's equipment, the backpack plays a central role. It must meet specific criteria of lightness, comfort and functionality to accompany runners over varied terrain and during demanding competitions. This guide details the technical aspects to consider when choosing a trail bag adapted to the needs of top-level athletes. See our best trail bags and other trail equipment.
The capacity of a trail bag depends on the duration and type of race. Bags generally range from 5 to 30 liters. For short races or training sessions lasting a few hours, a lightweight bag of between 5 and 10 liters may be enough to carry the essentials: hydration, nutrition and small items of equipment. For ultratrails or longer runs, opt for a larger model (12 to 30 liters) to carry more water, food and extra clothing.
It's crucial that the bag has an efficient internal organization with accessible compartments to avoid wasting time during the race. The best bags, such as those offered by Dynafit, Camp or Millet, often feature a multitude of easily accessible pockets on the shoulder straps or waistbelt.
The comfort of a pack is of paramount importance for long-distance mountain tours. A good pack should fit the shape of your back perfectly, without causing chafing or imbalance. The presence of an adjustable system with straps enables optimal adaptation to different morphologies, while stabilizing weight during the race.
To avoid excessive accumulation of sweat on the back, choose breathable materials that promote good ventilation during your intense efforts.
Hydration is essential in trail running, which is why many trail runners are equipped with integrated systems such as water pouches or shoulder strap flanges for quick access without stopping.
Some brands also offer modular options that allow you to add or remove reservoirs according to your specific needs during your run.
Make sure your choice not only keeps you well hydrated, but also light on your feet.
The materials used must be light yet resistant, so opt for fabrics such as ripstop nylon, which stand up well to the frequent abrasions encountered on rough trails.
Don't forget that robustness doesn't mean heaviness! Also check for sturdy zippers designed for ease of use, even when wearing gloves.
In short: choose wisely, because your equipment must be able to withstand all weather conditions!
Think about it: Choosing the right bag requires careful consideration of several functional aspects: necessary volume vs. optimal comfort vs. acceptable weight!
