The purpose of this article is to identify urban sports zones (also known as sports cities) as a potential product of urban or sports tourism in Poland using the spatial dispersion indicator of residential buildings in relation to sports infrastructure buildings. In the study orthodromic distances (the shortest distances in Euclidean space) between over 7 million residential buildings and 5.4 thousands sports facilities were calculated using centroids of buildings data included in the Topographic Object Data Bank (BDOT10k). These orthodromic distances were then used to calculate the dispersion coefficient in order to identify concentration zones of sports infrastructure buildings. The outcome of the study was the distribution of sports infrastructure buildings in Poland along with concentration zones where communes were treated as functional units. The findings can be used to identify areas that could serve as sports cities, which are defined as varied, separate, large areas, whose development is associated with sport and recreation.
