The French National Olympic Committee (CNOSF) challenged people to walk, run or cycle 2,024 metres – a distance symbolising the arrival of the Olympic Games in Paris in 2024. Launched for Olympic Day, the #DÉFI2024M campaign reached 12,000 participants from 24 countries across the world.

Each of the participants could take a picture of themselve to share their participation on social networks. All the images were then collected to create a giant dynamic fresco, revealing an image emblematic of the history of Olympism.

It was open to the world and 24 countries took part in the challenge: Hong Kong, Belarus, Bosnia, Brazil, Canada, China, Croatia, Germany, Guatemala, India, Ireland, Italy, Hungary, Malaysia, Palestine, Peru, Poland, Portugal, Romania, Russia, Serbia, Switzerland, United Kingdom!
