What annual New Year's Eve race in São Paulo, Brazil, was first held in 1925?

The annual New Year's Eve race in São Paulo, Brazil, first held in 1925, is the Corrida Internacional de São Silvestre.

The São Silvestre Road Race is an internationally known street race held in São Paulo on December 31. It was founded by journalist Cásper Líbero, who was inspired by nighttime races he had seen in Europe. The event was named for Saint Sylvester, whose feast day falls on December 31.

The first race took place in 1925, and the event later developed into a major mass-participation road race. Its course, distance, and competitive format have changed over time, so modern descriptions should not assume that every edition used the same route.

The race is often simply called São Silvestre in English-language coverage. That shortened name can refer to other Saint Sylvester races internationally, while the full name identifies São Paulo's famous New Year's Eve event.
