THE HOSTS' football team took gold today, as did new champions in triathlon, badminton and golf, while Mo Farah and Nicola Adams added to their collection of Olympic titles
Farah completes his golden double-double
Following his victory in the 5000m and 10,000m at Rio 2016, Great Britain's Mo Farah became the first man in 40 years to retain both titles. He was in control throughout the latter stages of the race, always near the front while other competitors came and dropped back. In the end, Ethiopia's Hagos Gebrhiwet took silver, and American Bernard Lagat claimed bronze.
Jorgensen runs away with triathlon title
USA's Gwen Jorgensen confirmed her position as the pre-eminent triathlete of her generation when she raced to an emphatic Olympic triumph on the Copacabana seafront, hitting the afterburners two kilometres from the finish, leaving her closest rival Nicola Spirig trailing to take the gold medal.
Jorgensen became the first defending world triathlon champion to win the Olympic crown the following year, as she dominated her rivals in the 10km run to win in one hour, 56 minutes and 16 seconds, some 40 seconds clear of Swiss defending champion Spirig.
Adams repeats historic feat
Great Britain's Nicola Adams was at her energetic best taking on Sarah Ourahmoune in the women's flyweight final, becoming the first British boxer to retain an Olympic title for 92 years by winning the gold medal. The 33-year-old from Yorkshire swept the scorecards 39-37 to become the first two-time women's Olympic boxing champion.
Olympic golf a walk in the Park
Inbee Park cruised to victory with a five-shot margin, with Lydia Ko of New Zealand taking silver and Shanshan Feng of China picked up the bronze.
The Hall of Famer never looked like loosening her grip on the gold as she struck birdie after birdie. The gold was the Republic of Korea's 20th, making Rio 2016 the eighth straight summer Olympics at which the country has won at least that many medals.
Chen not to be denied by Lee
Chen Long won gold in the men's singles final on his second attempt, defeating Malaysia's Lee Chong Wei, who had to settle for a third-straight Olympic silver medal. The Chinese athlete walked away from London 2012 with bronze but has risen to the top of badminton's ranks since then, winning the last two world championships.
Magnificent, unbeatable USA Team
USA won another gold medal with a comfortable 101-72 win against Spain, continuing a winning streak dating back to Barcelona 1992. Having defeated Spain by 40 points in the preliminary round, USA were strong favorites coming into the gold medal match and did not disappoint, claiming their sixth consecutive Olympic gold in women's basketball.
Serbia crowned kings of the pool
Serbia's wait for an Olympic men's water polo title is over, after they over-powered defending champions Croatia 11-7 (3-2, 3-1, 3-2, 2-2) in the gold medal match at the Olympic Aquatics Stadium.
Caster Semenya wins 800m gold for South Africa
South Africa's Caster Semenya won Olympic gold in the 800m but Great Britain's Lynsey Sharp missed out on a medal as she finished sixth.
Semenya, 25, set a national record to win in one minute 55.28 seconds and finish well clear of silver medallist Francine Niyonsaba of Burundi.
Kenya's Margaret Nyairera Wambui took the bronze medal, while Scot Sharp set a new personal best of 1:57:69.
Semenya, who has been subject to gender testing, won silver in 2012.
Taha Akgul wins Turkey's first gold medal in Rio
Taha Akgul won Turkey's first gold of the Rio Olympics by beating Iran's Komeil Ghasemi in the men's -125kg freestyle final.
Akgul, 25, beat his 28-year-old opponent 3-1 to add to his world titles from 2014 and 2015.
Turkish wrestlers had already won two silver medals and two bronzes at Rio 2016.
