Running is one of the easiest ways to improve your fitness, clear your mind, and get in shape. Although many people think all you need to do is put on your shoes and head out, it is often running clothing that determines whether you enjoy your training or want to give up after just a few minutes.
A poorly chosen layer can cause overheating, getting cold, and chafing. On the other hand, properly selected clothing helps you focus only on your performance and the joy of movement.
The golden rule of dressing for running and the layering principle
The basic rule is simple: dress as if it were 10 °C warmer outside. You should feel slightly cold during the first few steps – your body will warm up on its own.
The key to comfort is the so-called layering principle.
The first layer is the most important – it wicks sweat away from the body, so cotton does not belong here. Functional materials or merino wool are ideal.
The second layer serves as insulation. This typically means lightweight fleece sweatshirts that retain warmth while remaining breathable.
The third layer protects against wind and rain – ideally lightweight running jackets with a membrane, such as Siberium, that do not prevent moisture from escaping.
How to dress for running according to temperature
Each temperature calls for different running clothing.
Running clothing in winter below 0 °C
In winter, it is not about the number of layers, but about combining them correctly. The foundation is insulated leggings, a functional long-sleeved shirt, and a lightweight jacket.
Do not forget accessories – a hat, gloves, and a neck warmer, because the most heat escapes through the head and neck.
Transitional season: spring/autumn, 10–17 °C
This is where most runners make a mistake and dress too warmly. Even at 17 °C, a short-sleeved functional T-shirt is often enough.
It is useful to have a lightweight windbreaker or running vest as a backup. For your legs, choose leggings or shorts depending on how you feel.
Hot summer weather above 25 °C
In hot weather, a simple rule applies: the less, the better. The foundation is a lightweight, breathable T-shirt, shorts, and headwear.
The material must dry quickly and wick sweat away effectively so that it does not stick to the body.
How to adapt your clothing to running intensity
The perceived temperature varies significantly depending on intensity.
During a slow run, you will not warm up as much – add one extra layer. On the other hand, during interval training, you warm up quickly, so it is better to remove one layer.
Trail running is a specific category. Choose more durable clothing and do not forget a packable windbreaker, because the weather can change within minutes.
Shoes make the runner
You will not get far without the right shoes. Road running shoes are lighter and suitable for asphalt, while trail shoes offer better grip on uneven terrain.
Important features include cushioning, stability, and enough room in the toe box, ideally 0.5–1 cm.
Enjoy your run to the fullest
Stick to three basic rules:
- layer your clothing
- do not run in cotton
- dress as if it were 10 °C warmer
These principles will help ensure comfort in any weather.

Frequently asked questions
How do I know if I am dressed correctly?
You should feel slightly cold at the beginning. If you feel warm right away, you are wearing too many layers.
What clothing should I choose when it rains?
A lightweight waterproof or water-repellent jacket that is also breathable.
Can I run in a cotton T-shirt?
You can, but it is not recommended – cotton absorbs sweat and stays wet.
When was running invented?
Running has been a natural human movement since prehistoric times.
What is the difference between trail and road running clothing?
Trail clothing is more durable and designed for rough terrain, while road running clothing is lighter and more breathable.
