Olympic Marathon (Women)

The 2024 Paris Olympic Games promised to revolutionize the Olympic and Paralympic Games experience for the general public. Many people shared a dream that is now a reality: with the Paris 2024 Mass Participation Marathon, amateur athletes will be able to run the same route as the Olympic marathon, by night, enabling as many people as possible to follow in the footsteps of outstanding athletes.

Olympic Track & Field

All track & field finals for the 2024 Paris Olympic Games will be held during the evening sessions (some finals had been held in the morning during the 2016 and 2020 Olympics). The marathons will remain in the morning, though the men’s marathon will no longer be held on the final day of the Games, as had been tradition. That honor for the first time will go to the women’s marathon, which will be held on August 11.

An iconic distance, the 100-mile race starts from Auron and quickly reaches the highest point of the course at more than 2,650 meters above sea level: the Rabuons and its unique landscapes along the Chemin de l’Energie to the final stretch along the coast will take you to the coveted finish on the Promenade des Anglais..

Olympic Cycling Road Race (Women)

The road race, in which all riders set off at the same time in a mass start, is highly a tactical feat of endurance. Often, the race (over 120km for the women, and over 200km for the men) is won in a sprint finish over a few hundred meters, which means riders need to position themselves perfectly and conserve their energy in the first part of the race.
