WHAT'S BEHIND RUN24?
RUN24, AN ADVENTURE TO EXPERIENCE AS A TEAM OR SOLO
At Run24, we don't just run.
We laugh, we share, we push ourselves. Together.
Run24 is our way of reinventing endurance racing: 24 hours to experience as a team or solo, on a loop punctuated by effort, emotion and celebration.
Behind this concept, it's us:
OC Sport and the Léman Sport association
For over 20 years, we have been designing and organizing sporting events in running, cycling, triathlon, trail running and sailing.
Our DNA: to create powerful human experiences, where performance meets pleasure.
Why Run24?
And why not?
Because we believe that a challenge can be both intense and joyful.
Because we wanted to break the rules of ultra and invent a more collective, festive, accessible format.
Because running at night under the stars with your friends, dancing between two relays, or encouraging others around a food truck… that’s also the sport we love.
WHAT US
ANIME
The energy of the collective
Running together, encouraging each other, taking turns, feeling the excitement at every turn.
At Run24, the collective is the driving force of the adventure, from the first lap to the last.
The taste for exceeding expectations
24 hours requires mental strength… and above all, a lot of heart.
Everyone progresses at their own pace, pushes their limits and seeks much more than a stopwatch.
The festival atmosphere
DJ sets, entertainment, lights, food trucks and chill zones.
Run24 is a village that lives day and night, where running meets partying.
Strong values
Sustainability, diversity, kindness and authenticity guide every decision.
Here, everyone has their place and experience counts as much as performance.
OC SPORT,
IN A NUTSHELL
We are based in Switzerland and France, we work with passion, and we love seeing people excited at our events.

the Generali Geneva Marathon, Run Mate by Core Lean Lake Geneva, the Balexert 20km of Geneva, the Evian and Geneva Triathlon, the Abalone Marathon of Nantes, the Skoda 24-hour bike race, the Amarris Côte d'Amour Marathon, and mythical sailing races such as the Route du Rhum Destination Guadeloupe, the Transat Paprec, the Arkéa Ultim Challenge….
Run24 is our latest creation. And we hope you'll love it as much as we think you will.
