EJC day is on Saturday. There are nine races on the card. The first two races, at 1 pm and at 1.30 are outside the EJC competition, though some of the riders in the EJC competition have been engaged to ride in these races. Races 3, 4, 5, 6, 7, and 8 are EJC races. Each of the 12 riders in the competition will ride in at least 5 of the 6 competition races, and will be awarded points according to his finishing position in his five best races. The final race in the afternoon will be the celebrities race. Josef Vána senior will ride in this race. If he wins the race, it is believed that he will be the oldest rider, at the age of 66, ever to win an official race in the Czech Republic.
