Given the popularity of the event, you probably don’t want to be late.

The Salomon EcoTrail Paris continues expanding its trail running universe with its autumn edition, designed to extend the racing season right into the heart of autumn near Paris.

EcoTrail Paris Autumn: Trail Running in Greater Paris Nature

Far from the idea of Paris being purely urban, EcoTrail has always focused on a unique mix of nature, heritage, and proximity to the French capital.

The autumn edition keeps that same DNA, with routes crossing natural areas west of Paris, offering a true trail experience… without needing to travel hours away from the city.

This autumn edition includes:

• 80 km Trail — the ultimate endurance challenge for long-distance trail runners.
• 50 km Trail — a demanding but accessible format for experienced runners.
• 20 km Trail — a great entry point for discovering trail running or stepping away from road races.

Whether you’re an experienced trail runner, a marathoner looking for a new challenge, or simply curious about trying trail running, there is clearly a distance for you.

Why Registration Day Could Move Fast

EcoTrail is no longer a hidden gem in the French running scene.

Its unique format — combining forests, heritage sites, and nature just outside Paris — attracts thousands of runners every year.

The event has established itself as one of the leading trail races in the Paris region thanks to its combination of outdoor sport, accessibility, and environmental values.

Some distances tend to fill up quickly.

So if you already have your autumn race goal in mind, the advice is simple:

October 27 — 12 PM — set your reminder.

Which Distance Should You Choose?

A quick guide depending on your runner profile.

You’re New to Trail Running or Coming from Road Racing

The 20 km Autumn race is probably the best starting point.

Long enough to experience trail running, terrain management, elevation changes, and pacing — without immediately jumping into ultra territory.

You’re Preparing for a Bigger Endurance Goal

The 50 km can be an excellent seasonal challenge.

A strong format to work on endurance, fueling strategy, pacing, and mental resilience.

You Love Long Adventures

The 80 km is the flagship challenge.

A full day of trail running for those who enjoy long distances, managing highs and lows, and pushing their limits.

Autumn Is One of the Best Seasons for Trail Running

There’s something special about autumn trail races.

Cooler temperatures, seasonal landscapes, a different atmosphere compared to spring events, and sometimes more technical terrain…

For many runners, it’s actually one of the best times of the year to race.

And being able to experience a true trail event so close to Paris is a major advantage.

No need to organize a full mountain weekend to take on a serious challenge.

Registration officially opens October 27 at 12 PM.

What If Your Friends and Family Can’t Be There? Get Encouraged Anyway

Preparing for a trail race — especially distances like 50 km or 80 km — isn’t only about physical training.

There are tough moments, mental lows, and times when you start wondering why you signed up in the first place… and sometimes, a simple encouragement can completely change your race.

But not everyone has friends or family available to support them in person on race day.

That’s exactly the idea behind Cobbr.

The app allows runners to receive personalized voice messages from loved ones during their race, triggered at specific kilometers chosen in advance.

Imagine reaching km 28, km 45, or the final section of an 80 km race… and suddenly hearing the voice of a friend, partner, family member, or running crew encouraging you to keep going.

A unique way to keep your support crew close — even from a distance.
