The first track and field final of the Rio Olympics produced results that were nothing short of remarkable.
After a blistering early pace in the women's 10,000 meters, Almaz Ayana of Ethiopia broke away from the field past the halfway mark of the race and crossed the finish line in world record time of 29 minutes, 17.45 seconds.
The stat line for the race was, well, also remarkable.
Ayana's time was over 14 seconds ahead of the previous world record. Behind Ayana, all of the top 13 finishers set personal bests. In total, eight national records and 18 personal bests were set.
