This is a great video of JBS winning the 1500 m gold in the world championships the other day. People are commenting on her shock and disbelief after she wins, but what I notice is her calmness and composure the entire race. There is a fall, right in front of her, she avoids it without breaking stride. And during her delayed slingshot, there is not tightening up, no tenseness, just smooth striding it out home. What an awesome race, yeah Jenny!
