A remarkable night of athletics unfolded at the Zurich Diamond League on Thursday, with two world records tumbling within a single hour. Brazil's Alison dos Santos and American Masai Russell delivered stunning performances, etching their names into the record books.
The crowd and the energy were perfect. I think this night was amazing for me, for those who came to watch, I did it for everybody.
Dos Santos shattered the men's 400 metres hurdles world record, clocking an astonishing 45.80 seconds. He surpassed the previous mark of 45.94 seconds set by Norway's Karsten Warholm at the Tokyo Olympics in 2021. Warholm, competing in the same race, finished second with a time of 46.69 seconds.
"The crowd and the energy were perfect. I think this night was amazing for me, for those who came to watch, I did it for everybody," dos Santos said, expressing his elation. He credited his coach, describing him as a father figure who believed in him from a young age, for making the achievement possible.
I hope that Brazil stopped to watch this as much as the people here in the stadium. This has been an incredible night, I have no words to explain what happened other than I just broke the world record.
Shortly after dos Santos's feat, Olympic champion Russell set her own world record in the women's 100m hurdles. She powered over the final barrier to finish in 12.09 seconds, erasing the previous record of 12.12 seconds set by Nigeria's Tobi Amusan in 2022. The 26-year-old dos Santos has been a consistent challenger in the 400m hurdles, securing world gold in 2022 and silver in 2025, alongside Olympic bronze medals.
I was looking for my coach since I crossed the finish line. I was the one running, but he is the one who made this possible, someone who believed in me when I was younger.
The meet also featured other notable performances, including Saint Lucia's Olympic champion Julien Alfred winning the women's 100m in a national record of 10.70 seconds, and Kenya's Emmanuel Wanyonyi winning the men's 800m in the fastest time of the season, 1:41.76.
He helped me to develop both as an athlete and as a person, too. He's like an older brother, like a dad to me.
