Since 2009, Sébastien Cornette, founder of École de Trail, has been shaking up the codes of classic running training. His method is based on a strong conviction: to make running accessible to all. And that's what La Sportive Outdoor is all about! We spoke to Sébastien to find out more about his new initiative, the Trail Summit, which will take place in Aix-les-Bains on November 22 and 23, 2025.
Another vision of training
Trail School was born of a simple observation: classic training models don’t suit everyone. “I never wanted to do level groups,” explains Sébastien. “I wanted everyone to be able to train together, regardless of their VMA, goals or sporting background.”
This inclusive approach, conceived from the outset for “Mr and Mrs Everyman”, has won over a wide audience, especially women. ” With us, you come as you are. And today, the majority of trail school participants are women. . “
But this openness does not mean an absence of requirements. The method is based on three pillars: muscle strengthening, running technique and physiological development. “At each session, we work in a structured way, with a real intention behind the exercises.”

Sébastien insists: “We don’t want people running between injuries. We want them to stay fit, healthy and, above all, want to come back. “One indicator of success? The loyalty rate: ” In a classic club, you’ll often find 30% of members at the end of the year. In a trail school, it’s between 85 and 90%. “
A method that’s spreading
Today, the École de Trail is a network of over 900 trained coaches, including around a hundred accredited schools. Each coach follows a structured curriculum (level 1, level 2, certification) and benefits from ongoing support. The method is harmonized on a national scale, thanks to common planning, while remaining adapted to local conditions.
“It’s like Les Mills fitness. If you do a session in Strasbourg or Biarritz, you’ll find the same logic. The session is adapted to the terrain, but it’s the same philosophy. “
This rigor doesn’t prevent us from constantly questioning ourselves. ” Our method is evolving, because it’s based on people. We’re open to adjustments, but we’re sticking to our foundations. “
And above all, the method is not limited to trail running. “We work with cyclists, biathletes… all endurance disciplines.” The ambition is clear: to offer a multisport training and coaching model, backed up by an innovative mobile application designed to motivate members.
Trail Summit: a special event
In keeping with this philosophy, the École de Trail is organizing the very first Trail Summit in Aix-les-Bains on November 22 and 23, 2025 . A unique event, designed to combine theory, practice and conviviality.
“We wanted a conference that wasn’t just for professionals, but that also didn’t fall into the trap of being ultra-simplified for the general public.The result was a rigorously-constructed program featuring researchers, sports doctors, physical trainers, coaches and athletes, all experts in their field but also selected for their ability to make cutting-edge knowledge accessible.
On the menu:
- Conferences on topics such as nutrition, women’s sport, training children and injury prevention.
- Practical workshops (mobility, kettlebells, running technique…)
- And a festive gala evening, because conviviality is also one of the fundamentals of the Ecole de Trail.
Theevent is open to all, from the seasoned coach to the curious amateur runner. ” The main theme is health and performance. And above all, to stop pitting the two against each other. “
If you can’t make it, you can also attend the event remotely.
Sébastien sums up the intention of Trail Summit as that of his entire adventure: “To share knowledge, create links, and get people moving in a different way.“
La Sportive Outdoor will be there, see you there?
