Ethiopia's Ayana shatters World record to win 10,000m
Ethiopia's Almaz Ayana smashed the world record to win the Olympic 10,000 metres title on Friday, blowing away the competition in one of the greatest ever long-distance races at the Games.
Ayana ran boldly from the start and halfway through the race she surged away from the leading pack, injecting staggering pace to finish in 29 minutes 17.45 seconds. Her time was 14 seconds inside the 29:31.78 set by China's Wang Junxia in 1993.
Kenya's world 10,000m champion Vivian Cheruiyot tried in vain to keep up with Ayana but had to settle for silver while Ethiopian Tirunesh Dibaba, the defending Olympic champion, grabbed bronze.
Britain's Stanning and Glover dominate again
Britain's Helen Glover and Heather Stanning extended their five-year unbeaten run and claimed their second consecutive gold medal in the women's pair in the Olympic rowing regatta.
As is their style, the Britons led from the start in one of the most highly anticipated finals of the rowing event and a win had by no means been guaranteed.
The world and Olympic record holders led their nearest challengers by more than three-and-a-half seconds at the half way stage and by roughly four seconds at the 1,500-metre mark.
New Zealand's Rebecca Scown and Genevieve Behrent left it late to make their mark but moved up in the last stretch to take silver.
Germany's Junghaenel wins rifle gold
Henri Junghaenel of Germany walked away with a gold medal in his first Olympic Games by winning the 50 meter rifle prone event.
Having scraped into the finals in the last of eight positions, the 28-year-old Junghaenel established an early lead with several successive 10.8 shots, shy of the perfect 10.9.
Kim Jonghyun, 31, of South Korea, won his second Olympic silver with a perfect 10.9 shoot-off with Russia's Kirill Grigoryan, who took the bronze.
Junghaenel finished with a 209.5, 1.3 points over Kim, but shy of his 2013 world record finals score of 211.2.
Dutch take women's lightweight double sculls
The Netherlands duo of Ilse Paulis and Maaike Head claimed gold in the lightweight women's double sculls the Olympics rowing regatta on a rain swept Rodrigo de Freitas Lagoon, the second Dutch medal in rowing at this year's Games.
Canada took silver 1.1 seconds behind the Dutch women and China bronze.
Manuel and Oleksiak tie for 100m freestyle gold
Canadian Penny Oleksiak and Simone Manuel of the United States were inseparable at the finish and even more united in joy after a stunning 100 meters freestyle dead-heat rewarded both with Olympic gold.
Both women, one 16 and the other 20 and very much part of a new wave in swimming, touched the wall in 52.70 seconds as the crowd gasped at the times flashing up on the scoreboard.
Sweden's Sarah Sjostrom, the Olympic 100m butterfly champion who took the bronze in 52.99, was astonished.

Britain finished in 5 minutes 58.61 seconds, 1.83 ahead.
Australia took silver and Italy finished a distant third.

Germany's Mirian Welte and Kristina Voegel beat Australian duo Anna Meares and Stephanie Morton for bronze, denying Meares a sixth Olympic medal.
