When is the 2027 Lyon Half Marathon?

On Sunday 3 October 2027, as part of Run In Lyon by Harmonie Mutuelle. The 2026 edition was run on 4 October.

When does registration open for the 2027 Lyon Half?

On 13 October 2026 at 2 pm for licence holders and pre-registered runners, and on 15 October at 2 pm for everyone. Pre-registration is on the official website.

Is there a cut-off at the Lyon Half?

Yes: 3 hours to finish. Runners overtaken by the end-of-race vehicle are taken out of the race and continue on open roads.

Semi-Marathon de Lyon: how many weeks of preparation?

For an athlete at intermediate level, Endu builds a 13-week preparation. If your race is closer, the plan compresses phases while keeping the taper; if it's further away, it lengthens the preparation, and when the gap is large the preparation starts right away, gently and at your current volume, before building up.

How many sessions per week?

This example has 4 sessions per week. You choose 3 to 7 training days and the exact days (e.g. Tue, Thu, Sat, Sun): the plan sticks to them.

I'm a beginner, is this plan for me?

The plan adapts to your declared level (beginner to semi-pro): starting volume, progression and intensity change. Endu also offers a "Discovery" mode without a race to build a base first.

Can I follow sessions on my watch?

Yes, on Garmin and COROS. On Garmin, the Endu app (Connect IQ Store) shows today’s session and starts it as a guided workout. On COROS, link your account from your profile: your running, trail and cycling sessions land in the watch calendar. Other brands are not supported yet.

How much does it cost?

14-day free trial, then €7.99/month with no commitment or €59.88/year (€4.99/month). Unlimited objectives and sports.

The 2026 course

Start outside the old courthouse, in Vieux Lyon. The course follows the Saône along Quai Pierre-Scize, passes through Vaise (km 3), runs along Quai Paul-Sédaillan past the Île Barbe (km 6), then up to the Paul Bocuse bridge at Collonges-au-Mont-d’Or (km 8). Back along the other bank, Quai Clemenceau in Caluire (km 10), then Quai Joseph-Gillet to Les Subsistances (km 15). The route then enters the Presqu’île by Place des Terreaux, crosses the Rhône on the Morand bridge, loops through the 6th arrondissement around Place du Maréchal-Lyautey, comes back down the Rhône banks and Quai Victor-Augagneur (km 20), then recrosses the Rhône on the Guillotière bridge to finish on Place Bellecour. Full aid stations around km 5, 11 and 15 and at the finish.

What the race asks of your training

A course along the quays

On the 2026 map, the first fifteen kilometres follow the Saône quays, out to the Paul Bocuse bridge at Collonges and back along the other bank: long, steady stretches where you can lock in your pace. Key sessions are at half-marathon pace (3 × 3 km, then 2 × 5 km) and at threshold, to hold the rhythm for a long time without surges.

A more urban finish

After km 15, the 2026 course enters the city: Place des Terreaux, the Morand bridge, the 6th arrondissement, the Rhône banks, then the Guillotière bridge to Bellecour. More turns and two crossings of the Rhône just as fatigue sets in: finish a few long runs with 15 to 20 minutes at half-marathon pace to learn to push on when tired.

Running with your own container

No cups or bottles are handed out: volunteers fill your reusable cup, soft flask or hydration pack at the aid stations, every 5 km (three on the half). Do your long runs with the container you will use on race day to get used to refilling it and drinking on the move, and test your gels on them too.

3 hours to finish

The time limit is 3 hours, about 8:30 per kilometre: a first half is within reach of anyone who can run for 2 hours without stopping by the end of the build-up. Pacers cover targets from 1h35 to 2h10: pick yours from your training, not from how you feel on the day.

Why this plan works

Science-based periodisation

Base → build → specific → taper, with a recovery week every 3 to 4 weeks. Load goes up, but never two hard weeks in a row without a breather.

Paces, not vague feelings

Every session has target zones (pace, HR) computed from your MAS or a reference performance. A MAS test is built into the plan if you don't know yours.

A plan that listens

After each session you rate how it felt (RPE). Too hard? The plan eases what follows. Skipped a session? It reschedules or absorbs it.

On your watch

On Garmin with the Endu app, on COROS by direct sync: the guided workout shows up on your wrist, step by step.

“I used to spend more time looking for a plan than following one. Now I have my sessions, I know what to do and I stick to it. Really glad I tried it.”
Thomas · Running
“Training for my first half marathon and honestly, I’m getting into it! I even look at my next sessions ahead of time, when before I was mostly looking for an excuse not to go out 😂”
Camille · Running
“Simple to follow and really handy with the watch. I start my session and off I go.”
Julien · Running
“I took Endu to prepare a trail race with friends. I really like having my week already organised: it motivates me and I enjoy my runs more.”
Émilie · Trail
“What I like is no longer asking myself a thousand questions before going for a run. I follow the plan and I enjoy training.”
Nicolas · Trail

Julie · Trail
“A good find to prepare my swimrun! It’s nice to find a plan for this sport. I’ve recommended it to my teammate.”
Antoine · Swimrun
“I run more regularly and, above all, with more desire. For that alone, I’m delighted.”
Laura · Swimrun
“For triathlon, having all three sports in the same schedule really makes my life easier. I spend less time organising my training and I still enjoy following it just as much.”
Maxime · Triathlon
“At first I just wanted to try it. Now checking the next day’s session has become my little evening ritual 😊”
