A true 100 miles. A true legend.

There are trails that people talk about.
And then there are those that people whisper about, with a mixture of respect and excitement.

The GT160 returns in May 2026, after three editions that left their mark on bodies and memories.

A unique 100-mile race in Belgium, crossing deep forests, lakes, castles, and the hills aptly namedthe Blue Ardennes(
). TheBlue Ardennes.

A magnificent course.
Demanding.
True.

Here, we don't look for the easy way out.
We look for the truth.

100 miles.

Not just a distance – a seesaw.

The GT160 is a total challenge:
endurance, lucidity, mental resilience, humility in the face of the terrain and oneself.

You pass through several towns, several landscapes, several states of mind.
The night. The silence. The long hours.
Then dawn breaks and you understand why you came.

This is not a performance.
It is a rite of passage.

A race that matters. Really.

The GT160 is:
A qualifying race for the Western States 100 lottery;
Awarding a UTMB 100M index;
The only race in Belgium to combine these two distinctions.
Proof that this 100-mile race is not a copycat event but a respected, recognized, and legitimate race.

New edition. New layout. Same DNA.

For 2026, the GT160 returns with:
A revamped track
Even more aesthetic
Even more consistent
Even more wild

But it retains the essentials:
Authenticity
High standards
Greatness
The pioneering spirit

The GT160 will remain Belgium's most prestigious and challenging ultra marathon. 

A human adventure. Life-size.

There are those who collect medals.
And those who, one day, decide to measure themselves against 165 km of truth. 

The GT160 isn't for everyone.
And that's what makes it precious.

If you line up at the start...
It's because you know why.

New online race.

The GT160 is a journey.
From point A to point B. 

Just like in life.

You're making progress.
Always.
