While the 2016 Olympic machine is remodelling its hosting city Rio de Janeiro into a even more charming place, amateur daily sport activities have been long since shaping its social fabric. Rio de Janeiro's curvaceous landscape is the quotidian theatre for thousands of people practising former and present Olympic sports. Whether cyclers or runners on the promenades, or handball players on city's beaches, their metropolitan routine contributes to create the collective sense of space, transforming the nature into a huge free-of-charge outdoor gymnasium. And it is here, where the magic happens: Rio's sport natural theatres become the places where different cultures sociably meet and, freely and fearlessly, experience their collective identity.
