Tokyo Olympics: Peter Burling, Blair Tuke's 49er gold medal race postponed due to lack of wind

Kiwi sailors Peter Burling and Blair Tuke will have to wait another day, before potentially winning their second Olympic gold medal.

The defending Games 49er champions were scheduled to compete in the medal race in Enoshima on Monday evening, but a lack of wind has caused a postponement to all racing.

Burling and Tuke hold a slim four-point lead heading into the 10 boat race-off, ahead of Great Britain and Spain, where a top-two finish will guarantee gold for the dynamic duo.

Should the Kiwi crew finish ahead of the Brits and Spanish, they will also be guaranteed the gold medal.

The 49er medal race is now scheduled for 4:30pm NZ Tuesday.

The delay to racing also means the men's 470 crew of Paul Snow-Hansen and Dan Willcox have had their schedule pushed back, with the New Zealanders sitting just outside the medal spots in fifth - five points back from a bronze medal with three races to go.
