In November happens the Maratona Ecológica Internacional de Curitiba ("Curitiba International Ecological Marathon"). This marathon is known as the hardest in Brazil, because happens in the end of the year, when there usually is warm weather in the city (because it is summer in the Southern Hemisphere), and the hilly course, with many of the inclines being in the last 10 km. To compensate the hard course, runners count with good structure and enthusiastic fans cheering along the course.
