5 trail races to do in Brussels and its surroundings

1. Brussels Trail

📍 Brussels - Sonian Forest

📅 October 19, 2025

🏃 From 10 to 25km

THE The Brussels to Sonian Forest trail is a timeless classic , like fries on Saturday night. Except here, you replace the ketchup with roots, dead leaves (often wet), and a 100% enchanted forest atmosphere.

Between the gentle singles that wind under the giant beech trees, the little climbs that gently warm your thighs, and the descents that test your ankles, it's the perfect race to start trail running .

Muule tips: Choose trail shoes with a good grip because in the Sonian Forest, when it slips... well, it slips. Think of the running belt to take on board gums and compotes.

2. Lasnoise night trail

📍 Lasne

📅 November 7, 2025

🏃 From 10 to 23km

Welcome to the trail that is run with a headlamp (and flair)

The Lasnoise night trail is not just a race. It's a sensory experience, a total immersion in the night , with its mysterious woods, its muddy paths and that awkward moment when you realize that you have confused a volunteer with a road sign (it sounds like real life).

On the program: Climbs that surprise you because you see them too late. And descents where you will put your life in the hands of your headlamp .

Muule tips: Don't forget your headlamp with good battery life (unless you want to try going blind). Put on a trail fleece and light gloves , It's freezing at night.

3. Team Marathon Trail

📍 Vilvoorde

📅 December 6, 2025

🏃 From 10 to 42 km (depending on the number of team members)

There Team Marathon Trail de Vilvoorde is the race that turns your friends into teammates... or into idiots. Here, there's no question of everyone running the 42 km together: each team, up to 4 runners , takes turns on 10.5 km loops . It's an opportunity to run in turns, to encourage each other and to experience the race as a real collective adventure.

Little Muule tips: Equip yourself with a hydration vest because depending on your friend for a drink always ends badly . Think about trail shoes with good grip . And above all, keep smiling because in the end, it's still fun (and a good excuse for a beer in Vilvoorde).

4. Trailberg

📍 Everberg

📅 May 3, 2025

🏃 From 7 to 21km

Fancy a trail that goes up ... and down (a lot)?

The Trailberg is a bit of a surprise: hilly terrain , zigzagging paths , and a name that literally means "mountain." (don't worry, it's not Everest either... but your calves won't have the same opinion after 15km). Between the hills that make your thighs burn , the fast descents where you feel light as a gazelle (until the famous treacherous rock), and a rural setting that reminds you that a stone's throw from Brussels you can find real trail terrain .

Muule tips: A lightweight windbreaker jacket because Berg often means drafts that whip the back of your neck. A good dose of irony, useful when you discover that the hill you were told would be "gentle" turns out to be more piquant than expected.
And if you want to give your calves a little boost , telescopic trail poles won't be too much for the climbs.

5. EuropaTrail Brussels

📍 Brussels

📅 September

🏃 From 5 to 87km

THE Europa Trail Brussels is the race that takes you slaloming between asphalt and trails, a true urban-nature mix . Here, you start from the concrete and dive straight into the forests , parks and green trails that surround the capital.

It's the perfect trail to discover Brussels differently , a little bit of city, a lot of nature, and a maximum of fun.

Little Muule tips: Hybrid shoes that aren't too stiff or too soft, so you can handle both asphalt and dirt. Lightweight shorts so you can move freely. A breathable technical t-shirt to stay dry even when your heart rate is pumping.
