Ethiopia's Almaz Ayana smashed the world record to win the Olympic 10,000 meters title on Friday, blowing away the competition in one of the greatest ever long-distance races at the Games.
In only her second competitive 10,000m, Ayana dominated 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.
It was the first time in seven years that a female athlete had run 10,000m in under 30 minutes and the first four all achieved the feat. The first 13 women across the line clocked personal bests, including five national records.
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.
All three women ran inside the old Olympic 10,000m record.
Cheruiyot, Kenya's most decorated female athlete, also fell short in the 2012 London Games where she took bronze, meaning east African country's wait for its first women's 10,000m gold medalist continues.
The 31-year-old Dibaba, who returned in 2016 from a two-year layoff following the birth of her son, was seeking to become the first woman in Olympic history to win an individual athletics event three times in a row.
Ayana will now turn her attention to her preferred 5,000m distance, in which she is favorite to win and become only the second woman after Dibaba to claim gold in both the 5,000 and 10,000 in the same Games.
