"RELENTLESS" a film by Simon Nieves
A 44-minute documentary about Mathieu Parent, captured in the days surrounding a 450-kilometre unsupported cycling race through the mountains of Southern France.

THE STORY
The film begins in Nice.
In the days leading up to the race, Mathieu prepares for the challenge ahead. Food is organised, equipment is checked, the bike is packed, and time is spent with the people closest to him.
Through conversations with his partner and parents, a broader picture of Mathieu’s life gradually begins to emerge.
As the race unfolds, the film moves beyond the physical challenge and begins to reveal the experiences that have shaped his relationship with fear, uncertainty and gratitude.
Relentless is concerned not only with what Mathieu is doing, but with the perspective and experiences that sit behind it.
AN INDEPENDENT FILM
Relentless was filmed over ten days in and around Nice, France.
The project was produced independently, without the support of a traditional production company.
SIMON NIEVES
Simon Nieves is a Danish filmmaker, photographer and art director based in Copenhagen.
His work focuses on human stories, personal experiences and the individuals behind visible achievements.

Relentless is his debut documentary film and represents several months of independent production and development.
RELENTLESS
By the time Mathieu reaches the finish line, the race is no longer the central subject of the film.
Instead, it becomes the framework through which a broader portrait of Mathieu and his perspective on life is presented.
Relentless is not simply a film about endurance.
It is a film about perspective.
