The International Race São Silvestre, one of the most traditional street races in the world, was idealized by Cásper Líbero. In 1924, the journalist, then in France watched the “March aux Flambeaux”, a night race, in which athletes carried lit-torches. Enthusiastic with the idea, Cásper promoted in São Paulo, on the last day of December of 1925, at mid-night, this sports competition that got its name from the patron-saint of that day: São Silvestre.
Until the 20th edition, São Silvestre was a national race. As of 1945, it started receiving South-Americans and, in 1949, the event became international. In 1975, the female race was created as a tribute to the International Year of the Woman, created by the United Nations Organization.
In order to follow through with the demands of the International Federation of Amateur Athletics (IAAF), in 1991, the route expanded to 15 kilometers. Currently, around 15 thousand people, amateurs and professional runners, take part of the race which starts in front of the Masp and arrives in front of the building of A Gazeta, on Avenida Paulista.
In 1994, the race began its Children´s race: São Silvestrinha, which is made within the same rules of professional events.
