The city will become a meeting point for sport and solidarity with an activity aimed at raising awareness about rare diseases and showing citizen support for those living with them. The event will take place at the Dehesa Boyal Municipal Sports Center during the morning.
Promoted in collaboration with the ADNita association, the event will feature a bicycle set up in the sports center's entrance hall. Residents can participate by cycling for a few minutes, symbolically contributing to the cause. Additionally, a collective cycling class will be offered for the occasion, adding up the kilometers covered by all participants in a collective gesture.
Rare diseases, which affect a small number of people, impact millions worldwide. Despite their low individual prevalence, collectively they are significant. Many of these pathologies require complex diagnosis and ongoing care, making initiatives like this crucial for social awareness and highlighting the needs of those affected and their families.
The City Council reaffirms its commitment to solidarity, participation, and inclusion, using sport as a tool for awareness. Cycling becomes a symbolic vehicle to send a message of support, demonstrating how community effort can create a visible impact.
Residents of San Sebastián de los Reyes are encouraged to participate in this day that combines physical activity, community, and social commitment, aiming for greater knowledge and visibility for rare diseases and those affected by them.
