As part of the 19th edition of the national campaign "A Daffodil Against Cancer", the connected challenge of "The Daffodil Race Against Cancer" allows each person to run, from March 14 to 26, 2023, the greatest number of kilometers at the pace of their choice.

The objective is to wear the colors of the daffodil, universal symbol of the fight against cancer, in order to raise funds for research conducted at the Curie Institute.

The application of the Challenge against Cancer allows to count from March 14th to March 26th 2023 the kilometers of participants around the world.

Each activity, walking and running, allows to increase the global counter in kilometers but also that of the team. A ranking of the most mobilized team during these 12 days will be established
