Detailed description (English): A cultural, recreational, and competitive walk, which also includes a social route called "Zerogradini," conceived by the Oratory of the Seminarino and the Union of Alumni of the Seminarino of the Parish of the Cathedral of Bergamo, organized by ASD Steel Triathlon in collaboration with C.S.I. of Bergamo, Runners Bergamo, Senzacca lavoro di comunità, and "L'Eco di Bergamo." The aim of the event is to revitalize the ancient pedestrian access routes to the Upper Town and to raise awareness of the city's monuments and main cultural institutions, encouraging participants to explore and visit them. The principle adopted by the organizers in their relationships with the various institutions can be summarized as follows: "Millegradini brings visitors to you; you show them who you are and what you do." Alongside the tourist and recreational walk, there is a competitive race similar to a mountain run which, although held in the city, has attracted a growing number of athletes. The "Zerogradini" was added to these in 2014.
The event is split into two days: Saturday, September 20th and Sunday, September 21st.
