After a rigorous selection process, COMPRESSPORT has unveiled its very first Youth Trail Team, made up of seven promising young athletes.
Representing France, Switzerland, Spain, the United Kingdom, and Slovenia, these athletes were selected not only for their outstanding potential in mountain running, but also for their dedication and passion for this demanding sport.
The COMPRESSPORT Youth Trail Team was created to support the new generation of mountain runners.
These young athletes will receive all the guidance and resources they need to grow within their discipline.
With ambitious goals set for some of the most prestigious international races, the brand is excited to follow their journey throughout 2025 and beyond.
For the most promising among them, opportunities to progress to the elite level—within the COMPRESSPORT Elite Trail Team—will also be possible. Last month, the team came together for the very first time. It was a unique experience for these young runners, who met the COMPRESSPORT crew, received their new gear, and immersed themselves in the brand’s world.
Over the course of several action-packed days, the group took part in physical assessments, product workshops, and content creation sessions.
They also had the privilege of training alongside Diego Pazos, a prominent member of the COMPRESSPORT Trail Team, who shared his expertise during a technical downhill session.
A rare opportunity to train with one of the best on the circuit—and to sharpen their skills for the next chapter of their journey with COMPRESSPORT.
