Run together. Build your trail.
Trail Running Lab is a living trail running ecosystem.
A place where trail runners meet on the ground, train together, test gear, share effort, and build something bigger than individual performance.
Our community connects real people, real trails, and real experiences — every week, in multiple cities, with a long-term vision of progression and adventure.
A community born on the trail
Trail Running Lab grew from a simple idea:
performance starts with consistency, and consistency grows stronger in a group.
We bring runners together through:
weekly social trail runs
testing sessions with leading trail brands
immersive events and training camps
shared challenges and collective stories
The goal stays constant: progress together, on and off the trail.
Weekly Trail Runs
Every week, Trail Running Lab brings runners together for group trail runs in Annecy, Marseille, Nantes and Paris.
These runs are open to all levels and built around a simple idea: share the trail and progress together. Multiple pace groups allow everyone to run at their own rhythm, with a focus on consistency, connection and enjoyment.
No pressure.
Just movement, nature and a community moving forward — together.
More than runs: a real trail culture
Gear & nutrition testings
We regularly collaborate with trail and outdoor brands to organize:
shoe testings
hydration packs and equipment trials
nutrition strategy testing (gels, bars, fueling plans)
Everything happens in real trail conditions, during community runs or dedicated events.
Events that bring people together
Trail Running Lab events mix:
sport
education
recovery
human connection
They are designed to create memories, learning, and shared effort.
A team built on shared adventure
The Speed Project — Chamonix to Marseille
Last summer, the Trail Running Lab team took part in The Speed Project, running 430 km in 36 hours, from Chamonix to Marseille, in relay, day and night.
This collective effort shaped the foundations of our community:
shared responsibility
trust between teammates
resilience under fatigue
joy in reaching a common goal
Trail Running Lab grows from this mindset.
Individual strength gains power when carried by the group.
Trail Camps — immersive experiences to go further
Trail Running Lab trail camps are immersive training experiences designed to step out of routine and accelerate progression.
Across the season, we organize focused trail camps and stages in mountain environments, combining:
structured trail training
terrain and elevation adaptation
recovery protocols (sauna, massage, mobility)
nutrition strategy and fueling practice
coaching and feedback led by Antoine Clément
These camps bring together motivated runners who want to train with intention, recover properly and learn through experience.
From short mountain immersions to full-week stages, Trail Running Lab camps offer a unique balance between performance, recovery and community energy.
Our community mindset
Trail Running Lab stands for:
respect for all levels
discipline and consistency
shared effort over ego
long-term progression
passion for the mountains
Whether you train for your first trail or your next ultra, you belong here.
