Trail running is an intense sport that places heavy demands on the legs. Choosing the right short is therefore essential. It must provide freedom of movement, comfort and performance. Here is everything you need to know to choose the right trail short.
Key takeaways:
- Breathable and resistant synthetic fabrics are the way to go.
- The size of your trail short should be adapted to the distance covered and the weather conditions.
- Integrated shorts liners improve support and reduce chafing.
- The carry belt, pockets and reflective markings provide comfort and safety.
The best fabrics for choosing your trail short
Trail running shorts are designed to guarantee comfort and flexibility while running. When choosing your trail short, you can look at different **synthetic fabrics**.
**Polyester is lightweight and breathable**. It wicks moisture and dries quickly, making it ideal for intense races or in warm weather. **Nylon is durable and resistant** to tears. It is recommended on more technical trails or in areas with dense undergrowth. **Spandex adds elasticity** and a good fit for greater comfort and freedom of movement. It is therefore an excellent choice for mountain running. Meanwhile, **mesh** is often used for the ventilation panels of shorts to keep runners cool and dry.
Most trail brands favour **blends of synthetic fabrics**. These offer a good balance between lightness, flexibility and durability. Some fabrics also benefit from a water-repellent or antibacterial treatment.
Choosing the length of your trail short
The choice of trail short length depends on the distance you run, the climate and personal preferences. If you are taking part in a race, don't forget to check the regulations to find out whether a specific length is required.
Short shorts (between 10 and 15 cm) are **lightweight and promote freedom of movement**. They are therefore perfect in warm weather and during training sessions or fast races (under 20 km).
Mid-length shorts (between 15 and 20 cm) provide **better protection against chafing** and external abrasion. They are perfect for medium distances (between 20 and 50 km) and in cool or wet conditions.
Finally, long shorts (20 cm or more) offer **protection, muscle support and warmth**. They are recommended for long distances (over 50 km), in cold conditions and during changeable weather. If you're running in the mountains, also consider choosing your trail poles to better manage ascents and descents.
Do you need a 2-in-1 short with an integrated base layer?
When choosing a trail short, athletes can opt for classic styles or 2-in-1 shorts with an integrated base layer. They are very popular thanks to their comfort, support and protection against chafing.
**2-in-1 shorts integrate a brief, boxer or cycling short**. They eliminate the need to wear a separate base layer, which reduces the risk of chafing and improves comfort. Runners looking for thigh support particularly appreciate the integrated cycling short for **muscle support or compression**. It reduces vibrations and is therefore especially useful over long distances.
For women, it's also possible to opt for a skort. This skirt with integrated shorts is ideal for summer outings.
The details that can make a difference
Certain details help you choose one trail short model over another. The **integrated carry belt** is a good alternative to a pack for carrying essentials on short outings. Generally made from a stretchy material, it provides optimal hold without bouncing.
Well-placed pockets make the short more practical. **Lateral pockets** are useful for carrying easily accessible items. The **zipped rear pocket** is perfect for securing your keys or phone. Finally, **waterproof pockets** protect sensitive items such as your phone or card. For optimal protection in wet weather, it's also important to choose the right trail jacket.
**Reflective markings** are a must for those who run in the dark. They keep you safe and ensure you are visible to vehicles and other trail runners.
Finally, details such as **flat seams or heat-bonded seams** reduce irritation. Elastic waistbands or **drawstrings** adjust the waist for a good hold without excessive compression.
Choosing your trail short is therefore not a decision to take lightly. The ideal model must be suited to your running style and race conditions. By opting for a comfortable fit and practical details, you'll get the most out of your outdoor outings.
