Elaine Thompson-Herah made history, while Karsten Warholm blasted the world record in the men's 400 metres hurdles in a frantic day of athletics action at Tokyo 2020.
Jamaican sprint star Thompson-Herah completed the 100m and 200m double becoming the first woman to defend each title at the Olympics having won both in Rio five years ago.
There was also a slice of history for Anita Wlodarczyk in the women's hammer and Athing Mu romped to victory in the 800m.
Here's a round-up of all the best action from the track and field on Tuesday.
THOMPSON-HERAH REIGNS AGAIN
It has been another Olympics to remember for Thompson-Herah, whose winning time of 21.53 seconds is the fastest ever in the women's 200m.
The 29-year-old stormed out of the bend and left her rivals trailing in her wake to take a commanding victory.
Christine Mboma of Namibia claimed the silver in a world under-20 record of 21.81 with Gabby Thomas of the United States completing the podium.
WARHOLM SMASHES RECORD IN RACE FOR THE AGES
Norwegian sensation Warholm absolutely destroyed his own 400m hurdles world record (46.70) with a blistering time of 45.94. Nearest rival Rai Benjamin himself posted a 46.17 to take silver.
"This is so crazy. It's by far the biggest moment of my life," two-time world champion Warholm said.
"I've been training like a f*****g maniac. I struggled to sleep last night because I had this special feeling in my chest. It's like the feeling I had as a six-year-old on Christmas Eve. I was so focused on getting that last medal in my collection and now it's all complete."
Also in the morning session, world champion Malaika Mihambo saved the best until last to win gold in the women's long jump.
American Brittney Reese, the 2012 Olympic champion, and Ese Brume of Nigeria had traded the lead through the first five rounds until Mihambo posted the only seven-metre jump of the competition at the sixth attempt (recording exactly 7m).
Reese finished in silver behind the German, with Brume taking the bronze.
MARVELLOUS MU TAKES 800m CROWN
Mu, the world leader over 800m this year, took up the lead almost immediately from the off and never looked back to come home in a time of 1:55.21 – setting a new American record in the process.
Keely Hodgkinson made a strong charge late in the race and set a new British benchmark of 1:55.88 to take silver.
A personal-best time of 1:56.81 from Raevyn Rogers meant the USA had two women on the podium.
HISTORY FOR WLODARCZYK AS DUPLANTIS REIGNS SUPREME
There was a sense of deja vu in the women's hammer as Wlodarczyk successfully defended the title she won at London 2012 and Rio 2016 – making her the first woman to win a trio of golds in the same discipline at three straight Games.
Her throw of 78.48m was a season's best. China's Wang Zheng took silver thanks to a 77.03m on her last throw, while Malwina Kopron of Poland was third with a 75.49m. Coincidentally the podium line-up was the same as the 2017 World Championships in London.
Mondo Duplantis lived up to his billing in the men's pole vault to win gold at his first Olympics by clearing a distance of 6.02m.
The Swede has broken the world record twice since winning silver at the World Championships in Doha two years ago, and had a crack at going to 6.19m here after it was confirmed he had won gold ahead of American Christopher Nilsen.
While he fell short there, Duplantis still fulfilled his dream of winning Olympic gold and, at 21, has plenty of time to try and beat his own benchmark.
DE GRASSE COASTS THROUGH, LYLES ALMOST PAYS THE PRICE
Fresh from winning bronze in the men's 100m, Canada's Andre De Grasse was fastest in the men's 200m with a Canadian record time of 19.73 seconds in the third semi-final.
World champion Noah Lyles is also into the final but eased up during his semi to finish outside the automatic spots and had to qualify as one of the fastest losers.
In the first round of the men's 110m hurdles, world champion Grant Holloway clocked a 13.02s – faster than the time needed to win gold at Rio 2016 and the fastest heat time of any competition in history.
