Modern pentathlon
Australia's Chloe Esposito has won gold in the modern pentathlon with an Olympic record score of 1372 points.
It was Australia's first ever gold medal in the modern pentathlon.
She was sitting in seventh place overall after three of the five rounds of the women's modern pentathlon.
She was able to make up a 45 second gap to take the lead in the combined running and shooting events and opened up a massive lead in the final 800 metre run to the finish line.
Esposito, her brother Max and their father moved to Hungary this year to focus on improving her fencing, which was the weakest aspect of her event, and it paid off.
She was able to pick up a point in the fencing bonus round, in the 200 metre swimming leg she finished first in her heat and in the show jumping she picked up one obstacle penalty and two time penalties.
Her brother Max Esposito will compete in the same rounds in the men's competition tomorrow.
Walking
Walker Jared Tallent looked set to repeat his London gold success right up until the final minutes of the men's 50 kilometre walk.
In the closing laps of the race, Matej Toth overtook him and Tallent was unable to catch him.
