The first information said that the final on Saturday was 15 minutes late due to problems with the equipment at the start.
According to Thompson-Herah's husband and coach Derron Herah, it was about 25 minutes at Kingston National Stadium.
- I was frankly worried that she would not make it to the race without any ailment after the delayed start.
I'm just glad she did not wear anything.
With a 25-minute delay, anything can happen, Derron Herah told the Jamaica Observer.
The first three went to the World Cup
Here it could have gone really wrong.
Jamaica, like the USA, has tough performance requirements to get to the World Cup and it is the top three in each branch who make it to the championship.
- Part of me wanted to drop out of the competition but I had to remind myself to remember to qualify.
I do not have a wildcard and had to run to qualify, says Thompson-Herah who was third on her modest 10.89.
The late Florence Griffith-Joyner holds the world record of 10.49 from 1988. Thompson Herah is the second fastest of all time at 10.54 and has won the last two Olympic finals in the distance.
In Eugene, she is chasing her first individual World Cup gold in the distance.
