Our Community
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.
Our Events
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.
Our Newsletter
The Trail Running Lab newsletter is built for runners who want structure, clarity, and long-term progression.
Every week, you receive: clear training insights you can apply immediately; practical frameworks to structure your macrocycles and phases; field feedback from our Athlete Team and science-backed explanations tailored to trail and ultra.
We cover the full performance logic: base, general development, specific preparation, taper — and how to distribute intensity with intention to build real endurance and sustainable speed
