Brazil turned up hugely at the Maracanã as Neymar scored the fastest goal in Olympic history, while a new queen of the sprint was crowned on a scorching day some 7 hours from the amazon.
Below, we recap the action - which featured yet another plentiful supply of incredible moments.
- Mo Farah survived another scare in the qualifying for the 5000m as he almost fell on the final lap, but would end up coming third and securing a spot in the final of the event. On a sweltering morning in Rio, Hagos Gebrhiwet topped that first heat, while Paul Kipkemoi Chelimo was the winner in the second.

- Conseslus Kipruto strolled his way to victory in an exciting 3000m steeplechase final, celebrating as he eased down the final straight following some chaotic moments across the course.
- The other standout performer was Evan Jager, who lead for a big chunk of the race and took a silver medal for his efforts. However, the bronze medal spot was not without controversy, as a later appeal would strip Ezekiel Kemboi of his bronze medal. A review placed by the Frenchman Mahiedine Mekhissi who initially finished fourth was accepted, as the officials deemed the Kenyan went out of the lines after jumping over the water - a rather harsh decision that probably wouldn't have affected the decision anyway.
- In the 200m semi-finals, Usain Bolt had no trouble getting to the final, breezing to victory in his heat and even having time to once again give the cameras come gold, chatting with his Canadian opponent as they passed the finish line. However, he will not be joined by compatriot Yohan Blake, or more shockingly so, Tyson Gatlin, whose tactics cost him another shot at dethroning Bolt as he slowed down towards the end, unaware that he was to be overtaken by his opponents.
- Tianna Bartoletta jumped 7.17m to give the United States a gold medal, finishing one-two with Brittney Reese in the long jump final.
- Elaine Thompson was crowned the new "sprint queen" as she completed the double, edging Dafne Schippers in the final of the women's 200m, adding it to her 100m gold that she raked in for Jamaica. The two top athletes emerged from around the bend, but it was Thompson who grabbed it, with the Dutch athlete unable to keep up.
- Concluding the evening at the athletics stadium was the women's hurdles 100m final, featuring an all-American podium as Brianna Rollins took gold, while teammates Nia Ali and Kristi Castlin followed. Britain's Cindy Ofili came in fourth place.

- Rajiv Ouseph's run in the men's single badminton came to an end after he crashed out of the quarter-finals at the hands of Viktor Axelsen. The Dane topped the Brit in straight sets, while China's Dan Lin and Long Chen, along with Malaysian Chong Wei Lee will join him in the semi-finals.
- Indonesia clinched the gold medal in the mixed doubles by making light work of the Malaysian duo of Chan and Goh, winning the final set 21-12. They were represented by Ahmad and Natsir, who dropped to the ground in euphoria after their win.

- France's Estelle Mossely booked her spot in the final of the women's lightweight tournament, scoring a first-round TKO victory over Russia's Anastasiia Beliakova following a punch which appeared to break the competitor's arm. Meeting her to square off for the gold medal will be Junhua Yin, the Chinese southpaw who defeated Mira Potkonen on points.
- Savannah Marshall was the only Briton in action on day 12 of the games, and her competition came to an end after a split decision loss to Nouchka Fontjin of the Netherlands, who built an early lead which made it difficult for her opponent, even with a spirited conclusion, to get back in contention.
- Kazakhstan continued a dominant streak in Olympic welterweight boxing as Daniyar Yeleussinov secured a gold medal in the final against an aggressive yet ineffective Shakhram Giyasov.

- France added to their team eventing title by winning the team showjumping event, totalling just 3 faults, 2 of them time, as the team of R. Bost, Philippe Rozier, P. Leprevost and K. Staut assembled an impeccable display as their horses leaped over the coloured poles. The United States came in silver with a total of 5 penalties.
- Canada and Germany were tied on 8 penalties, leading to a jump-off for the bronze medal. Germany's first three riders went clear of the poles, while two of Canada's riders ended up climping them, putting the last podium spot in the hands of the Germans.
- Brazil blasted through to the final of the Olympic football tournament in front of a rocking crowd at the Maracanã, as they put six past a helpless Honduras side. Neymar scored the fastest goal in history inside just 15 seconds, and the hosts were flying from that point, with Gabriel Jesus' getting a brace and others pitching in, before a Neymar penalty late on closed the show in style. They will get a shot at redemption, after a catastrophic end to their World Cup campaign in 2014.
- Meeting them in the final will be the ones who ended said World Cup campaign. Germany saw past Nigeria after leading by one goal for the most part to finish it 2-0 as their football machine once again was in full flow.
- The Netherlands' women held their nerve in a dramatic penalty shootout, as they topped Germany to reach the final of the tournament. With nothing to seperate the nations after regulation, it went down to the dreaded one-on-ones, which too were stalemate, going to sudden death in which Ellen Hoog stepped up and excellently fired past the keeper.
- Great Britain stormed past New Zealand with a 3-0 victory, thanks to a duo of goals by Alex Danson and one by Helen Richardson-Walsh, guaranteing the 2012 bronze medallists a spot on the podium again, this time either silver or bronze.

- Less than an hour later, her compatriot Kaori Icho also snatched the gold medal late at the death, defeating Russia's Valeriaa Koblova Zholobova.
- Japan would top Russia again in the day as Sara Dosho ousted Natalia Vorobeva in the 69 kg category, with her point scoring more significant to issue her a gold medal - and solidify Japanese dominance in women's wrestling.
