The Cross Internacional de San Sebastián, also known as the Cross Internacional de Donostia, is an annual cross country running event which is staged in late January in San Sebastián, Spain. The competition was first held in 1956 as a men's only race and attracted top level runners from the outset, with Olympic gold medallists Emil Zátopek, Alain Mimoun and Mamo Wolde being among the winners in the first decade of the event. A women's race was introduced in 1971 and two-time World Cross champion Carmen Valero took a record four back-to-back wins soon after. From the 1970s to 1980s, a mix of Iberian and British athletes topped the podium, but since the 1990s the race has been dominated by runners of East African origin.
