Abstract
Nowadays, similar to worldwide trends, running has become very popular in the Czech Republic. Since the mid of 1990s, the business sector has become very active in this area.
Private companies organise many road races for the public, including participation of top level runners (i.e. Prague International Marathon).
In 2016, within the framework of the international project IRNIST, we realised an empirical descriptive study of the Mattoni 1/2 Marathon in Ústí nad Labem, a middle size town. The IRNIST questionnaire was used.
Analysing data on 491 runners (of 2,238 runners finished the race) we found that concerning socio-economic status of respondents, 56.9% of runners have a university education, one third advanced secondary education; and 63% earn more than the average wage. Participant were able to spend quite a lot of money for participation costs.
These results raise the issue if the privatization and commercialization of running for the masses does not cause limit for sport participation for all.
