but it was not until 1941 that a runner not from the city of São Paulo won the race: José Tibúrcio dos Santos, of Minas Gerais, another Brazilian state. At that time, the event was not yet open to foreign participation. That meant that athletes from other countries could not come in to participate, but foreigners residing in the city of São Paulo (immigrants) were free to enroll. Because of this, Italian Heitor Blasi was the only foreigner to have won the race before 1947. In 1945 the field was opened so that foreign runners could participate. The first international race was restricted to invited runners from South America, but the success of the first two "international events" led race organizers to open the event to the rest of the world in 1947. That year marked the beginning of a 34-year-long period during which no Brazilian man won the event, until José João da Silva, from Pernambuco, won in 1980 (he would repeat the feat in 1985). The event would remain a men-only affair until 1975, when the United Nations declared that year as the International Year of Women. In commemoration of this, the race organizers held the women's race for the first time. The women's race started as an open event, and the first Brazilian victory would come only in its 20th edition (in 1995), when Carmem Oliveira won. Starting December 31, 1982, Rede Globo began to telecast the road race via satellite to the whole of Brazil, in partnership with TV Gazeta. Since 1993, a shorter race for children is held a few days before the main event (dubbed "São Silvestrinha", or "Little Saint Silvester" – a unisex event). Until 1988, the race took place at the late night hour starting at 23:00, approaching the New Year's, but the year of 1989 - the year the race began to be recognized as an international running event - saw substantial changes in the race's format, in order to comply with the rules of the IAAF. The time of the race was altered for first afternoon (to 3:00 p.m. for women and 5:00 p.m. for men), the course direction was reversed, and men and women, who used to run together, had their races separated. In 1991, the length of the race was extended to 15,000 meters (the distance for the event used to vary almost yearly, usually between 6.5 km
