At the World Championships in Eugene, McLaughlin broke her own world record in the 400m hurdles by almost three quarters of a second.
She came home in 50.68 seconds, smashing her own record of 51.41 seconds set in June.
The sport is getting faster and faster according to McLaughlin.
From here, I get faster.
The United States' Dalilah Muhammad took the gold medal in 52.26, followed by the Netherlands' Femke Bol.
On the second occasion, Muhammad broke the world record, running 52.16 to beat McLaughlin and win the gold medal at the world championship.
McLaughlin has run five of the six fastest times in history in the past 13 months.
The women's flat 400m final was half an hour earlier than her winning time.
McLaughlin said that the presence of fans and family helped spur her on to a new level.
She said that the last 100 hurt but she was grateful to have this crowd.
My family was in the stands and it was amazing. I have never had them with each other.
Bol said it was strange to see McLaughlin's pace at the beginning.
Bol thought it was crazy. I was always questioning if I had a good race because she was so far ahead at the end.
She broke the 51-second barrier as well.
It is amazing to be a part of it and to finish second in such a race.
A change to the 400m flat is most likely, according to McLaughlin.
"Me and [coach Bobby Kersee] are going to go back after the season, decide if this is still an event I even want to do, or if we're going to find something else because we've accomplished so much in it," she told NBC.
