The Jamaican produced a stunning performance to blitz the competition in 10.61 and secure a third Olympic gold medal
The Jamaican’s flawless display in a scorching 10.61 seconds was enough to upset compatriots Shelly-Ann Fraser-Pryce and Shericka Jackson, who took silver and bronze respectively.
But the 29-year-old has suffered from injuries between her triumph at Rio 2016 and the Games this summer, picking up an Achilles tendon injury at the 2019 World Championships in Doha.
But Thompson-Herah persevered and overcame the pre-Games favourite Fraser-Pryce.
Thompson-Herah told BBC Sport trackside after her stunning performance: “God is amazing, I’ve been struggling, I see all the bad comments, I see everything, for me to stay focused and keep my composure.
“I use them as my motivation, to take me here today, more than enough. I felt it, I’m so excited to celebrate early, I’m grateful. I’m lost for words right now, that is amazing.”
