"The most challenging thing is to keep the vehicle in operation and the driver on alert," contestant Vratislav Veselý, who drove a BMW 315 dating back to 1934, told CTK. The retro race, started in 2015, has brought back a classic competition from the 1930s. Back then, the 1,600-km race followed the main road from Prague to Bratislava and back. This year, 117 classic cars made before 1939 took part in the competition.
