What a difference a year has made for Maxime Grousset and Noe Ponti.
Last summer, when the two sprint specialists took to social media to reflect on the Paris Olympics, they each opened up about the mixed emotions they felt. Both expressed pride in their accomplishments but also disappointment that they did not live up to their expectations of medaling in their individual events.
Grousset had finished 5th in the 100 freestyle and 100 butterfly (and was the 2023 world champion in the latter). He qualified for the 50 freestyle final but withdrew to focus on the 100 butterfly. Ponti won bronze in the 100 butterfly at the Tokyo Games, but finished a difficult 4th in the Paris final, adding to a 5th place finish in the 200 butterfly.
Their results began to turn quickly, though. On the final day in Paris, Grousset combined with Yohann Ndoye-Brouard, Leon Marchand, and Florent Manaudou to win bronze in the men’s 4×100 medley relay in front of a roaring French crowd, closing out the Games with his first Olympic medal. Ponti lit up the fall short-course meters season, which culminated two world records (50/100 butterfly) and three world titles at the 2024 Short Course World Championships (50/100 butterfly, 100 IM).
Both came into this year’s long-course season strong. Grousset clipped his 100 butterfly national record at the French Elite Championships (50.11), going faster than he did to win the world title in Fukuoka. Ponti fired off a 50.27 in April, which he backed up with two 50.4 performances at Sette Colli.
They showed off their form early in Singapore during the men’s 50 butterfly final. They pulled away from the rest of the field, with Grousset clipping Ponti by three-hundredths for the world title. Both swam national records, Grousset hitting 22.48 and Ponti 22.51. The effort marked Grousset’s second world title. For Ponti, it was the first long-course World Championship medal of his career.
“I go into the water wanting to win – not a medal, but to win,” said Ponti after the 50 butterfly final. “I used to be a bit nervous, and [get] nervous, but I think I have some experience now, and I need to try always to focus on my thing and on my race…that’s what I did, and what I’m doing in fact, so the results are coming.”
The results continued to come in Singapore. In tonight’s 100 butterfly final, the two’s sprinting ability was on full display. Grousset took the race out under world record pace with a blistering 22.80 split. Ponti was in medal position as well, turning third behind Thomas Ceccon, who had joined the two swimmers on the 50 butterfly podium.
Ponti out-split Grousset on the second 50 meters, 26.68 to 26.82. But Grousset held on to complete the sprint butterfly world title sweep. He hit the wall in 49.62, the third-fastest swim in history and under Kristof Milak’s 49.68 European record from the Tokyo Games. Ponti also cleared the 50-second barrier for the first time in his career, swimming a 49.83 for silver. They are the sixth and seventh men to get under that marker.

On August 3, 2024, both Grousset and Ponti looked up after the Olympic men’s 100 butterfly and felt disappointment their block light—which indicates winning a medal—was not on. 364 days later, they made their second trip to the World Championship podium as the gold and silver medalists in a butterfly final.
When asked what changed for him this week, Grousset had a simple answer, “I found more strength and more power in the water, that’s all.”
The men’s 100 butterfly has become an increasingly competitive event over the last couple of years. Now, Grousset and Ponti have established themselves as the men to chase. A year after Olympic disappointment, they have fought back onto the podium and are two of the fastest 100 butterfliers actively racing.
Standing on the podium is a strong position to start a new Olympic cycle from. But Ponti especially was clear that the Singapore podium is not the finish line. He rated his performance this week “nine-and-a-half out of 10. Only because I won silvers and not golds. But otherwise, it was 10 out of 10.”
Ponti went on, “I’m happy to be a part of these fast races and be on the podium even if it wasn’t so easy to win a medal. I was expecting to swim sub-50s today. In LA, [you’ll need] pretty much the same. 49.9 to make the podium.”
The bar has been set and it’s clear these two swimmers will play a crucial role in continuing to raise it in the charge towards the 2028 Olympics.
Quick Hits
Simona Quadarella Swims European Record For 4th In Thrilling Women’s 800 Freestyle Final

Simona Quadarella by Nardia Mulkerrins
Behind the fireworks of the three-way race for gold between Katie Ledecky, Lani Pallister, and Summer McIntosh, Simona Quadarella continued her exceptional meet. She swam 8:12.81, taking over the European record from Rebecca Adlington‘s super-suited 8:14.10 at the 2008 Olympics. The time breaks Quadarella’s previous best of 8:14.55 from last summer.
Quadarella moves up to the fifth-fastest performer of all time with the swim, just a half-second behind Ariarne Titmus‘s 8:12.29 from the Paris Games.
All-Time Top Performers, Women’s 800 Free (LCM)
- Katie Ledecky (United States) — 8:04.12 (2025)
- Summer McIntosh (Canada) — 8:05.07 (2025)
- Lani Pallister (Australia) — 8:05.98 (2025)
- Ariarne Titmus (Australia) — 8:12.29 (2024)
- Simona Quadarella (Italy) — 8:12.81 (2025)
Earlier in the meet, Quadarella earned silver in the 1500 freestyle with her first personal best in the event in six years. The 15:31.79 she swam for silver took down Lotte Friis‘ European record (15:38.88) from the 2013 World Championships. This 800 freestyle European record was five years older than Friis’ mark and Quadarella now owns the continental record in both women’s distance events.
Neutral Athletes – B Swim Second Mixed Relay European Record In Singapore
The Neutral Athletes – B committee, made up of the Russian swimmers approved for neutral status, has been on point in the mixed relays this week. After winning gold with a European record in the mixed 4×100 medley relay, the committee swam another European record in the mixed 4×100 freestyle relay, taking silver behind the U.S’s world record swim.

Egor Kornev led the team off in a 47.69 after placing 4th in the men’s 50 freestyle. Ivan Girev took over and put the team into second place with a 47.08. From there, the women took over. Daria Trofimova split 52.42, then Daria Klepikova brought the team home in 52.49. Klepikova has had an excellent meet so far, anchoring both medal-winning mixed relays and taking 4th in the women’s 100 freestyle with a Russian record.
They took down the European record Great Britain had held at 3:21.68 for the last two years, swimming 3:19.68.
The Neutral Athletes – B team also set themselves up for success in tomorrow evening’s 50 backstroke final. Kliment Kolesnikov and Pavel Samusenko are the top two qualifiers for that final. Kolesnikov, the world record holder, swam a 24.16 in the semifinal after a 24.06 warning shot in the heats. Samusenko qualified second in 24.31 and will face a tough fight with Pieter Coetze who added a third African record to his tally this week (24.32) in the semifinal.
Ben Proud Defends Olympic Silver, Swims 4th Fastest Time of His Career
Last night, Great Britian won its first medal in the pool at the 2025 World Aquatic Championships, striking gold in the men’s 4×200 freestyle relay. After the race, Matt Richards said “We really wanted to put in a performance tonight and not just get ourselves onto the medal table but get ourselves a gold and put us in a good position moving forward.”

Tonight, Ben Proud took up that mantle and ran with it. He earned the men’s 50 freestyle silver medal from lane seven, swimming a 21.26 to touch seven-hundredths behind world champion Cameron McEvoy. The time is the fourth-fastest in his career, faster than he went to win the first Olympic medal of his career last summer in Paris. The only times he’s been faster are the 2018 European Championship semis (21.11), 2018 Sette Colli (21.16), and 2024 British Trials (21.25).
He did so even while recovering from the illness that’s spread through the World Championships. “I was still suffering from the viral bug that was going around,” he shared. “All expectations just went out the window. The only important thing was getting through the rounds, making it to the final, and enjoying that process. The less-than-ideal run-up almost took the pressure off. I just aimed to get through the rounds, hoping to sneak a podium spot.”
Since missing the podium at the Tokyo Games, Proud has been remarkably consistent at earning a podium spot at major championships in the 50 freestyle. He’s been on the 50 freestyle podium at his last three major international long-course competitions. In 2022, he swept the event across Worlds, Commonwealth Games, and European Championships. Then, he earned bronze at 2023 Worlds and 2024 Worlds. Last year, he got onto the Olympic podium with a silver medal, a medal position he repeated tonight.
