This article has some good quotes from Bol:
"I came here for the best race of my life. And I ran one of my worst. I really don't get it."
"After 250 meters it really didn't work anymore. It was an extra blow that someone then also came over me. I really didn't expect that."
"At the last hurdle I suddenly took an extra step, which is just stupid. I'm just annoyed about this."
"I also started hard in La Chaud-de-Fonds and London. I managed it then. I don't understand it. I got upset at the end when Anna Cockrell came over me. That was my own fault. In itself it was logical. I knew in advance that Sydney could run there and that I had to keep doing my thing. This is really annoying."
"I didn't have the idea that everything was slipping out of my hands at that moment. The acidification just hit me harder. When the finish came into sight, I even thought for a moment that I would come fourth. You can't be serious, that was all that went through my head."
And some quotes from her two coaches:
It was all or nothing, Meuwly said afterwards. "Halfway through, Femke ran 0.3 seconds faster than during her personal record." She had no choice, it sounded almost apologetically. "She had to run like that in an attempt to win."
"An anticlimax," her other trainer Bram Peters called the final. "We trained for this for three years. We worked every day to make her a little bit better and to close the gap with McLaughlin. Today it had to happen. If it doesn't work out, it's painful. What remains for us is to gather courage and try to do better in four years' time in Los Angeles."
The final confirmed what Peters already knew. "McLaughlin comes from another planet. And so does Femke. Without McLaughlin, she would have been the greatest ever in the 400 hurdles. It's a shame for her that there is one person walking around who is just too good."
