Trail Running Lab is more than an app.
It’s a real-world trail running community, active every week.
We organize weekly trail runs in Paris, Annecy and Nantes,
regular brand testings, and soon immersive training camps in the mountains.
Different cities. Different terrains.
One mindset: progress together.
Trail Running Lab events bring the community together on the trail.
From weekly runs to brand testings and immersive trail camps, our events are designed to create real experiences where training, learning and connection meet.
Each event blends: shared effort, real-world gear and nutrition testing, coaching insight and community energy.
