May came to an end with the Mare Nostrum Tour - in Monte Carlo on the 23rd and 24th, Canet on 27-28th and, this weekend, Barcelona on May 30-31 -and the highlights of the six days of competition were two sub-052sec 100m freestyle swims from Marrit Steenbergen, of The Netherlands: 51.86 and 51.97, leaving the all-time top 10 performances list looking like this: .

Here's a short wrap of the action, focussed on swims that topped 900 points, with a link to our separate on Steenbergen's 51.86 and American Anna Moesch's 51.94 at the AP Race London International last weekend:

Steenbergen Slipstreams Up To Sjostrom With All-Time No2 51.86 Dutch Delight
Just two days after Anna Moesch rocketed to a 51.94 Americas records to become the 2nd fastest ever over 100m free, she’s now 3rd in the ranks, the Dutch reigning World champion shuffling the best-ever Top 10 yet again to bring Day 1 at the Canet round of the Mare Nostrum to a sizzling close
Moesch’s 51.94 Message To Dolphins: Eagles Are After Your 4x100 Crown at LA2028
Only Sarah Sjöström, the double Olympic 50-100m freestyle sprint champion and 51.71 World-record holder from Sweden, has ever swum faster than Moesch’s march past the 52s from 53.2. to 51.9 at the London International. Great expectations ahoy!

Round 3 - Barcelona

Day 2

Siobhan Haughey and Marrit Steenbergen concluded their tour rivalry in a 200m free final that saw the top series 400m swimmer, Erika Fairweather storm back into contention and miss her mark by just 0.27sec.

Victory went to Hong Kong's Haughey in 1:55.22, Fairweather on 1:55.49, not far shy off the 1:55.06 New Zealand record she set at nationals last month (which took down her 1:55.44 from 2023. Fairweather was 1.21sec shy of Haughey feet win the wall at the last turn, before chasing her Olympic medallist quarry with a 29.04 last length, to the winners 29.98.

Czech ace Barbora Seemanova clocked 1:56.64 f0r third place just ahead of Steenbergen, in 1:57.72 to bring and need to a tour on which the Dutch ace has shuffled the all-time top 10 performers and performances rankings with efforts of 51.86 and 51.97 in the 100m freestyle, the 4th and 5th swims ever to see a woman race below 52sec. The 200m race:

In the 50m free, Haughey faced a different Dutch opponent: Milou Van Wijk took the last dash of the tour in 24.33 ahead of the Asian ace's 24.45, with Taylor Ruck of Canada, enjoying two podiums a short space apart:

Steenbergen bypassed the 50 free but she would not end the last day of your without racing Ruck. The Canadian trailed American Leah Shackley 28.71 to 28.76 at the turn but a 29.95, the sole-0sub 30sec return in the race, had Ruck on 58.71 by the close of battle, the time a meet record and in the club of 900-point swims on tour this year.

Shackley was closest, on the clock and just 6 points shy of the 900 line, on 59.29, Ruck's teammate Ingrid Wilm on 59.63 and Steenbergen making it four inside the minute bringing the race to a close with a fourth sub-minute, on 59.59.

On the men's side, the 900-point-plus swim of the final day also set a meet mark, Ruck's former Canada teammate, Ilya Kharun, based in Arizona and now sporting American nationality, on 22.99 in the 50m butterfly. One of two neutral athletes in the top 4 at a meet in Spain (where, unlike Monte Carlo and Canet does not recognise the aggressor nations in the war on Ukraine), Oleg Kostin was next home, in 23.12, while third home was a man who turns 46 this year: Brazilian Nicholas Santos, on 23.31, and making a comeback in time for a shot at 50 'fly at LA2028 after the stroke dash events were added to the Olympic program for the next Games:

Marrit Steenbergen strikes again: after a 51.86 blast at the Canet round of the Tour, the Dutch World champion of 2024 and 2025 became the first woman to race inside 52sec twice in her career. A touch shy of her 51.86, Steenbergen, coached by Patrick Pearson, was out in 25.09, home in 26.88 for a 51.07. That compares to these best off class splits:
