The project SIGWAY Sports in Greenways aims to promote sports and healthy leisure activities outdoors by stimulating sport activities offered in greenways and potential greenways; while raising awareness of environmental issues and the circular economy. The Erasmus + project Sigway aims to promote sport and healthy leisure activities outdoors by stimulating sports activities offer in greenways and potential greenways, while raising awareness on environmental issues and circular economy. Moreover, Sigway aims at enhancing sports field employability and local economies. The origin of the Greenways programmes has been to avoid the loss of railway heritage and to maintain public ownership. The continuity of the whole line is essential, fragmenting the line by selling the land in sections is a serious problem, because it is not possible to establish continuous itineraries.Thanks to the greenways, the maintenance and recovery of railway infrastructure and heritage, in particular bridges and tunnels, is carried out, which would not be done without this use. Greenways are an ideal infrastructure for active mobility, active leisure and everyday sports, and sustainable tourism.
