Every two years there are the EYOFs (European Youth Olympic Festivals), both in the summer and in winter since 1991. About 2000 (summer) respectively 800 (winter) young athletes (between 15 and 18, according to the kind of sport) from 49 european nations are participants of these sportfestivals. The standard of performance is very high, because the participants are the best of their age and nation. Only Olympic disciplines are part of the program.
