Prokop qualified for the Czech squad, as the nation's sole male rider, in men's BMX cycling at the 2008 Summer Olympics in Beijing by receiving an automatic berth from the Union Cycliste Internationale (UCI) based on his top-ten performance from the BMX World Rankings. After he grabbed a twentieth seed on the morning prelims with a time of 36.689, Prokop scored a total of 18 placing points to take the sixth spot in his quarterfinal heat, thus eliminating him from the tournament.
