Olympic superstar Usain Bolt is keen to lock horns with the new 400m world record-holder in a sprint to see who's fastest.
Bolt wants to race Wayde van Niekerk over 300m to determine who is fastest, the Sydney Morning Herald reports. The distance is a compromise between the athletes' favoured lengths.
South African van Niekerk ran the 400m in a record 43.03 seconds on Sunday. Bolt holds the record for the 100m and 200m.
Jamaican Bolt, who today won his third successive 100m Olympic gold medal, said the competition could happen next season.
"Hopefully next season, if he is in good shape and my coach puts the meet on again, I get a chance to run. I would really like to compete against him over 300m; that would be good.
