Check out the gold medallists on Day 13 of the 2016 Olympic Games in Rio de Janeiro on Thursday:
Muhammad continues US hurdle streak
Dalilah Muhammad of the United States led from start to finish to take the Olympic gold medal in the 400 meters hurdles and complete a US double in the women's and men's events.
Denmark's Sara Slott Petersen won the silver medal ahead of Ashley Spencer of the United States, with world champion Zuzana Hejnova of the Czech Republic managing only fourth.
With steady rain pouring down at the Olympic stadium, Muhammad shot out of the blocks, rose quickest at the first hurdle and never looked like being overtaken.
She clocked 53.13 seconds to win by a margin of 0.42.
Petersen, the European champion, ran 53.55 seconds, and Spencer recorded a personal best of 53.72.
American Crouser wins shot gold with record throw
American Ryan Crouser hurled the longest throw of his life to win the men's shot put final, breaking the Olympic record and snatching gold.
The 23-year-old set three personal bests in the final and his longest throw of 22.52 meters shattered an Olympic record set by East Germany's Ulf Timmermann in 1988.
Crouser's victory, which followed Michelle Carter's last-gasp win in the women's shot put, took the United States back to the top of the men's podium in an Olympic event the country has dominated with 18 of the 28 gold medalists.
Crouser stunned his rivals to win the US Olympic trials and during the Games final he looked untouchable. He was the only man to throw over 22 meters, which he did three times.
Eaton wins second straight decathlon gold
American Ashton Eaton won his second straight Olympic decathlon gold medal on Thursday, tying the Olympic record after cruising to victory with a third-place finish in the final 1,500 meters.
Eaton ran a tactical race, keeping an eye on France's Kevin Mayer, who had threatened his position with strong showings in the pole vault and javelin throw. The 26-year-old Mayer took silver in the two-day event.
Eaton ran the first three laps easily, secure in his points margin and content to allow Algeria's Larbi Bourrada to win in 4 minutes, 14.6 seconds. The American ran down nearest points rivals Mayer and Canadian Damian Warner in the final 200m.
Warner, who had beaten the 28-year-old Eaton in the 100m with an Olympic best time of 10.3 seconds as well as in the 110m hurdles, snagged the bronze.
Canoe Sprint - Dominant Danuta wins second Rio gold
Hungarian kayaker Danuta Kozak fought off a fearsome pack of competitors to defend her Olympic title in the women's K-1 500 metres final.
Kozak, 29, claimed the fifth Olympic medal of her career and her second gold of the Rio Games in one minute 52.49 seconds, 1.82 seconds faster than silver medallist Emma Jorgensen of Denmark.
New Zealand's Lisa Carrington, who won gold in the women's kayak single 200 metres on Tuesday, uncharacteristically struggled throughout the race.
Carrington, who languished behind much of the pack at halfway, battled back to claim bronze in the final stretch.
Thursday's field featured five different Olympic medal holders.
Maryna Litvinchuk, a member of Belarus' 2012 bronze medal-winning K-4 team, took fourth place and Germany's triple medallist Franziska Weber was fifth, while five-time Olympic medallist Inna Osipenko-Rodomska of Azerbaijan finished last.
Kozak, who also took gold in Tuesday's women's K-2 500 metres, will seek a rare triple gold in the sport, returning on Friday for the K-4 500 metres heat.
Triathlon: Brownlee retains title in British family 1-2
Alistair Brownlee won the Olympic triathlon in dominant style on Thursday, outrunning brother Jonny in a British 1-2 to become the first to retain the title and underlining his position as the greatest-ever exponent of the swim-bike-run sport.
Jonny, 26, third in London four years ago, went one better to take silver after being outkicked by his 28-year-old brother in the heat of the concluding 10km run, with Henri Schoeman taking the bronze, South Africa's first medal in the sport since it was introduced in 2000.
The brothers delivered a textbook performance after coming out of the 1.5km sea swim off Copacabana beach and controlling the 40km bike leg.
They then surged clear on the 10km run, defying the heat, with Alistair walking across the line with a Union Flag held aloft.
"Every day has been so hard. I have woken up in pain every day." said the champion, who underwent extensive ankle surgery last year.
"We knew the first two laps on the bike would be crucial. The last few weeks we have been training to commit and boy we did.
Athletics: Clement wins 400m hurdles but Culson in tears
Kerron Clement, of the United States, held off fast-finishing Kenyan Boniface Tumuti to win the men's Olympic 400 metres hurdles.
Running with a relaxed, easy rhythm, Clement was the clear leader going into the closing metres, but had to dip on the line to deny Tumuti as the Kenyan came up fast on the outside, with Turkey's Yasmani Copello taking bronze.
It was Clement's first major championship medal since he won the 2009 world title, having taken the silver at the Beijing Olympics the year before.
Javier Culson of Puerto Rico was disqualified for a false start and sat sobbing by the side of the track before trudging away.
Badminton: Japan defeat Denmark to win women's doubles gold
Japan's Misaki Matsutomo and Ayaka Takahashi defeated Denmark's Christinna Pedersen and Kamilla Rytter Juhl to claim the women's doubles gold medal at the Olympics and secure their nation's first ever badminton title.
The top-ranked Japanese had to fight for every point against the determined Christinna Pedersen and Kamilla Rytter Juhl and dug themselves out of a huge hole to win an 18-21, 21-9, 21-19 thriller at the Riocentro.
Trailing 19-16 in the final minutes, Matsutomo and Takahashi won five successive points to crush Denmark's hopes of a first badminton title in 20 years.
Matsutomo and Takahashi went one better than compatriots Mizuki Fujii and Reika Kakiiwa who won the silver in the event at London.
Boxing - Cuba's La Cruz wins light-heavyweight gold
Julio Cesar La Cruz out-pointed Kazakhstan's Adilbek Niyazymbetov to become the first Cuban to win a light-heavyweight Olympic boxing gold medal.
France's Mathieu Bauderlique and Britain's Joshua Buatsi took bronze as losing semi-finalists.
The gold was Cuba's first in the ring at the Rio Games and the light-heavyweight division was the only one without a previous Cuban winner.
