500,000 competitors take part in mass events organised by A.S.O. and its British subsidiary Human Race every year. Tackling personal challenges, pushing the limits and sharing the effort with others: this is what runners find in A.S.O.'s half marathons and marathons, notably the Schneider Electric Marathon de Paris, "running festivals" held all over France, with a wide spectrum of distances suiting every athlete.

Similarly, thousands of riders flock to the Étape by, which gives cyclists around the world a taste of the Tour de France experience, as well as the cyclosportive versions of the legendary Paris–Roubaix and Liège–Bastogne–Liège classics, without forgetting the Roc d'Azur, the biggest mountain biking event in the world. Fans can follow in the footsteps of their idols and live their passion for sport to the fullest in events organised to the same high organisational and safety standards as elite ones.
