Operating from bases in Switzerland and France, OC Sport is a pioneering sports marketing and event management company specializing in outdoor sports and professional sailing. With nearly twenty events and over 80 days of racing each year, we create unforgettable outdoor sporting experiences in some of the world’s most stunning settings—from oceans and mountain roads to city centers.



For nearly thirty years, our mission has been to inspire, unite, and take action for more responsible sport. We are evolving our practices to reduce the impact of our events, preserve the regions that host us, and encourage everyone to adopt sustainable behaviors.



We design our events to serve as genuine platforms for impact. They raise awareness, mobilize communities, and give meaning to athletic performance.

At OC Sport, sport is experienced with passion, respect, and commitment.

Sport has its own rhythm—and so does nature.


OC Sport is a subsidiary of ADVENN.
