The partnership will see Decathlon kit out the 45,000 volunteers expected to work at the Games in the French capital.

They will wear eco-designed uniforms that will be specially created for Paris 2024.

Decathlon will also hold a number of Paris 2024-themed events at its 330 shops across France, which will include sporting challenges, events and initiatives aimed at all ages.

These will particularly focus on Paris 2024 host communities and the 1,800 Terre de Jeux locations - places where local authorities want to support the organisers of the Games.

Stores will also sell official Paris 2024 products with the first batch of items due to go on sale in the coming months.

"Almost three years to the day before the Paris 2024 Olympic and Paralympic Games, Decathlon has become an official partner," a Paris 2024 statement said. 

"From now on, the French brand will be contributing its expertise for the benefit of the biggest sporting event in the world, as well as kitting out some 45,000 volunteers, the indispensable games makers of the Paris 2024 Olympics and Paralympics.

"Paris 2024 and Decathlon share the same ambition - to make the Paris 2024 Games a festive, well-attended and unifying event to help promote sport and fitness for everyone in France.

"Decathlon hopes to use this partnership to share its values with the many - values of sport, vitality, respect, caring and excelling oneself - and to convey these to the next generations." 

Earlier this month, pharmaceutical company Sanofi signed up as the fourth top-tier sponsor of Paris 2024.

Technology conglomerate Cisco, lottery operator FDJ and sports equipment manufacturer Le Coq Sportif are the others.
