The Elancourt Hill, or The Revanche Hill, is located in Elancourt, in Saint-Quentin-en-Yvelines urban area, in the department of Yvelines (78), approximately 30km from the Paris city centre. In 2024, the Hill will host the Olympic mountain bike events. The area will also host the competitions of golf and fencing (modern pentathlon).

The impact resulting from this international event will contribute to making the Elancourt Hill a lifelong attractive sports pole.

The story of a quarry that became a wasteland

Before being the highest point in Ile-de-France with its 231 meters of altitude and a space of leisure and relaxation for its users, the Hill was notably an open air quarry.

Despite the artificial origin of the land, nature has gradually taken over this site, which remains mainly in a state of wasteland. Used by mountain bikers, walkers and runners, it is also a place for walking, near activity zones and residential areas.

The Elancourt Hill in 2025

The creation of additionnal tracks to the Olympic track created for the Games will offer new mountain bike routes accessible to sporty experts as well as the youngest. Facilities such as pump-tracks will be created and offer a different way of practicing mountain biking. Walkers and runners will enjoy safe spaces adapted to their activities.

Finally, relaxation areas will allow everyone to enjoy the view from the top of the Hill over the entire Ile-de-France region.

A development project that respects its natural environment

Since 2019, SOLIDEO has been conducting environmental studies to identify the natural areas located on the Elancourt Hill. More than 380 species have been inventoried on the Hill, including 255 plant species and 125 animal species.

The development project of the Elancourt Hill for the 2024 Games and for the 2025 legacy takes into account the environmental characteristics of the site.

The Hill during the Games

The Olympic Games will take place from July 26 to August 11, 2024. The organisation of the Olympic mountain biking events on the site offers a unique opportunity for the players to be part of a global event.

A 4km Olympic track will be created, taking up most of the existing tracks on the hill. The Olympic track has been designed taking into account the ecological constraints of the site. Temporary facilities will be set up to organise the sports events and welcome spectators.
