Lecheva recalled that on 17 May 1894 the first 10 physical education teachers arrived in Sofia from Switzerland with the task to lay the foundations of sport in Bulgaria. Among them, Charles Champaud and Louis Eyer were the most renowned. Football balls and various gymnastics equipment were brought for the first time to Bulgaria. The Swiss teachers also founded the iconic gymnastics organization "Yunak" ("Hero" - ed.). Charles Champaud was the first participant for Bulgaria at the Summer Olympics - in 1896 in Athens.

On the proposal of the State Agency for Youth and Sports and by a decision of the Council of Ministers of 4 August 2006, 17 May was declared the Day of Bulgarian Sport and a professional holiday for those working in the field of sport.
