There, they raced one-on-one. The nine winners advanced to the 1/8 finals, while the nine losers were sent to the first repechage. In the repechage, the cyclists were placed in heats of three cyclists apiece; winners moved back into the main competition by advancing into the 1/8 finals.
The twelve cyclists in the 1/8 finals again competed one-on-one. The six winners advanced to the quarterfinals, with the six losers getting another chance at the second repechage. This repechage also consisted of three-cyclist heats, with the two winners moving on to the quarterfinals.

In addition, the bronze medal competition was a best-of-three match between the semifinal losers. The classification race for 5th to 8th places was a single race with all four cyclists competing.
