2026 Mare Nostrum Tour – Monaco
Women's 100m Freestyle – Final
GOLD – Marrit Steenbergen (Netherlands), 52.13
SILVER – Siobhan Haughey (Hong Kong), 52.67
BRONZE – Camille Spink (United States), 54.55
In the women's 100 free final in Monaco, Sutch superstar Marrit Steenbergen fired off a new career best in 52.13, demolishing the Monaco Record of 52.60, previously held by Sarah Sjostrom from 2017, and makes her the fastest performer in the world this season, and keeps her at#8 all time in the event.
Steenbergen's time keeps her at the #8 spot in the all-time performers ranking, but the swim was faster than any other participant since Siobhan Haughey‘s 52.02 from the World Cup in Berlin in October of 2023, which made her the #3 performer all-time.
She previously held the top time in the world this season with her performance at the Bergen Swim Festival in April, where she battled with Haughey once again, coming out on top in 52.33 to Haughey's 52.40.

In Monaco, Steenbergen used a massive 26.62 closing split to take control over Haughey, who turned first at the halfway point (25.36 to Steenbergen's 25.51).
This swim marks a solid time drop for Steenbergen, who is the reigning 100 free world champion from Singapore last summer, with a time of 52.55. Her fastest time before this meet was from the 2024 World Championships in Doha, where she also won gold in 52.26.
That former time also stood as the Dutch Record in the event, which Steenbergen also bettered here.
