The final is part of the main program of the Zlatá tretra Ostrava race, which will take place on June 28, 2017. The legend of world athletics Jan Železný is the patron of Chocolate Tretry. The Chocolate Tretry plant has its roots in Ostrava, but it has been held for another five years in 18 other Czech cities. The aim of the race for children is primarily to promote the movement of children and to support the running of the game itself. Chocolate tretra also aims to bring fun not only for children but also for their parents. Puppies can be sent to parents by Wednesday 21 June 2017 to 20:00. Each child aged between 0 and 17 can participate in the race. Registration can only be done online, and the option will not be possible on the spot. Participation in Chocolate Cake is free for all.
