Performance isn’t just about your legs
It’s about what your body can actually process
Mission
For years, Jerome, co-founder and avid trail runner, faced the same issue over and over again:
-
Digestive problems
-
Nutrition strategies that failed
-
Races compromised despite solid training
And yet, he was doing everything “right”:
-
Testing products
-
Following advice
-
Copying protocols
Nothing really worked.
This is something many runners experience: improvised nutrition, lack of personalisation.
That’s where Atalen started
We set out to build a simple, structured tool:
-
To create reliable nutrition strategies
-
Tested in training
-
And adapted to each runner
Because in trail running, the limit is rarely physical
It’s energetic… and digestive.
Why Atalen
The name Atalen is inspired by Atalanta, a runner from Greek mythology known for her speed, but above all for her discipline and control.
She doesn’t win by chance: she wins because she manages her effort.
That’s exactly our vision: trail running doesn’t just reward strength and stamina; it rewards control and management.
Atalen stands for performance that is:
-
Smarter
-
More controlled
-
More sustainable
