The electricity company EDP sponsors popular marathons via the "Share your energy" communication platform. Running should be an accessible activity for everyone. But many women do not go running alone because they are afraid. Gender-based violence is a real threat that is on the streets. Until this is eradicated, women need initiatives that help them feel safe and that function as a wake-up call to society. This is how "Sincronizadas" was born, an app to put women runners in contact with each other so that they can go running in a group whenever they want. An idea that started a necessary conversation in society.
