On the first two editions, 94 dreamers thought about defeating the Monster... but only 42 manage to rise above the Citadel of Namur, the final barrier of this impossible course. Relive the Chapter II.

HEROIC

To become a Hero, all you need to do is deliver the final blow to the Monster. Isn't it child's play ?

LEGENDARY

Sweat and blood.

They have written The Ardennes Monster History., in golden letters.

BRUTAL

Many have walked on the steepest slopes of the Kingdom. Many have left a piece of their soul there...

Words of Heroes

"This is the toughest and most physically and mentally demanding challenge I have ever done.

The route and its characteristics stand out from any other event of its kind, making the race unique.

Be aware that the effort will be intense, distinct, perhaps even more so than a 'classic' ultra.

The atmosphere is strong and adds an extra dimension, and the communication about the event is effective, both for loved ones and participants."

« The event was first class. This was their first time organizing an event and it seemed like they had been doing this for years.

Many thanks go out to Olivier and his crew, they worked their asses off and put on a hell of an event.

I would highly recommend The Ardennes Monster to others. »

The question of The Ardennes Monster remains. I have experienced inner monsters at times : fears of what might happen. Also, monsters that seem to dominate our world temporarily, such as competition, selfishness, power – but also the division into winners and losers.

If the cycling event « The Ardennes Monster » contributes to us reflecting on the monsters within ourselves and in the world and leaving them behind to embark on a more just and solidarity-driven world, then I have long reconciled with the name of this loving and beautiful event.

An extra thanks to Olivier and his team who supported him in

organizing this loving event.
