It’s back! Get ready for a brand-new edition of Run In Lyon by Harmonie Mutuelle!
Whether you’re a beginner runner or a seasoned marathoner, come (re)discover the City of Lights at your own pace, in a lively and friendly atmosphere.
🏃‍♀️ Three race formats await you: 10K, Half Marathon, or Marathon.
Want to run for a good cause?
💙 Join the Run Solidaire (5K) in support of the AFG Autisme association.
And for the youngest runners, the Marathoon’s on Saturday promises an unforgettable first race experience!


Of course, we only want you to have fun during the race, but sometimes unexpected things happen. We suggest that you think about any insurance that you might need to ensure that Run In Lyon by Harmonie Mutuelle is an excellent day.
