The final originally took place on 1 September, but during its course Grażyna Rabsztyn veered off onto the neighbouring lane and caused Nina Margulina to fall down. Because of this the race was re-run a day later without Grażyna Rabsztyn, with the same athletes taking the medals in exactly the same order.
