Callan Lötter sweeps SA open water titles in dominant display

Teenage star Callan Lötter confirmed her status as South Africa’s leading women’s open water swimmer after defending all three of her national titles at the Bombela Concession Company SA Open Water Championships at Marina Martinique near Jeffreys Bay.

The 19-year-old delivered a commanding performance across the weekend, winning the 10km, 5km and 3km knockout races to complete a clean sweep of the women’s events.

Lötter set the tone in the 10km marathon swim where she proved untouchable, becoming the only woman to break the two-hour barrier. She won the race in 1:59:36, finishing more than four minutes ahead of Hannah Neilson, who clocked 2:03:54. Carli Antonopoulos secured third place in 2:04:51.

“It feels really good. I’m very proud of myself,” Lötter said.

“Last year I tried to stay with everyone and then take it out at the end. This year my training has been much better, so I decided to take it out from the beginning and try and hold on and build a gap.”

Her victory established clear water between herself and the rest of the field from early in the race as she controlled the tempo from the front.

Lötter added the 3km knockout title the following day in challenging conditions.

The format features three races in quick succession. The opening 1.5km round reduces the field to the top 20 swimmers, followed by a 1km race for the top 10 and a final 500m sprint after a ten-minute break.

“The race was really good, the conditions were very tough,” Lötter said.

“The waves were picking up quite a lot at the end, so you had to work much harder to finish the race, but I’m happy with how it went.”

She completed her hat-trick on Sunday in the 5km event, winning in 1:00:23 after fending off a close challenge from Neilson, who finished second in 1:00:37. Marony Jacobs placed third in 1:02:02.

“I was aware that Hannah was quite close to me on the first three laps and then I saw the rest of the pack was quite far behind,” Lötter said.

“So I tried to focus on my own race and see how far I could get ahead.”

While Lötter dominated the women’s races, the men’s 10km produced one of the most dramatic finishes of the championships.

Henré Louw claimed the national title in 1:54:46 after edging Byron Kimber by one second in a sprint finish. Connor Albertyn finished third in 1:54:55.

“It was definitely a tough race,” Louw said.

“The strategy was to sit back a bit this year and let the other guys do a little bit of work and then try my best at the back end of the race.”

The race took a dramatic turn on the final lap when Louw briefly lost ground.

“On the last lap I missed the buoy, I got pushed out a bit, so I had to turn back and I was probably about 30 metres behind those guys,” he said.

“I had to dig deep just trying to catch them on the last lap. When I got to the top buoy, I tried to push as hard as possible to the finish.”

Albertyn later secured victory in the men’s 5km race after another closely fought contest among the leading swimmers. He won in 57:26, finishing two seconds ahead of Matthew Caldwell, while Kimber placed third in 57:30.

“It was a very tough race. From the start to the finish, it was full pace from everyone,” Albertyn said.

“I don’t think there was a moment in that race when we were fully relaxed. We were constantly watching each other, especially Matt, Byron and Henré.”

Albertyn seized his opportunity on the final lap.

“I saw a bit of a gap and I took it. I kept my head down and kept pushing. I didn’t want to look back. I focused on the finish and doing everything I could to secure the win, and I managed to do so.”

Earlier in the championships, Caldwell won both the 3km knockout and the 3km race in 34:31. Leah Markgraaff claimed the women’s 3km title in 37:25 and also secured victory in the 7.5km race in 1:33:49. Wian Bartleman won the men’s junior 7.5km title in 1:25:47.

Making waves at Midmar: Louw and Caldwell front SA’s men’s charge

By Adnaan Mohamed

Like two powerful swimmers sighting the buoy and surging with intent, Henré Louw and Matthew Caldwell are set to lead South Africa’s men’s charge at the 2026 aQuellé Midmar Mile, determined to stop the foreign tide from washing over the podium for a third straight year.

With New Zealander Louis Clark (2025 winner) and Australian Nick Sloman (2024 champion) absent from the starting pontoon, the waters look ripe for a local breakthrough. But standing like a steady cross-current is three-time French Olympian Damien Joly, whose presence adds an unmistakable edge to the 5–8 February showdown.

Caldwell, who finished third last year, has no hesitation in calling his shot, speaking with the calm certainty of a swimmer who trusts his stroke count.

“I think I’ll call it now: top three, not in order, but top three will be amongst Henré Louw, Damien Joly, the French swimmer, and myself,” said Caldwell.

“We will be fighting for first, second, and third, us three, I think. That’s my opinion. There are a lot of other swimmers that are looking good at the moment, but right now I think in my books that’s the top three.”

Louw, twice the bridesmaid at Midmar, agrees that Joly is a major threat, but believes the race will be deeper than just three names treading water at the front.

“There are still other good guys like Sven van der Linde, who’s also going to be there, and there are a few guys that definitely can show up on the day, like Connor Albertyn as well,” Louw said.

“But I reckon that’s going to be the five guys in the mix that’s going to be really racing for the win.”

The numbers back him up. Connor Albertyn and Sven van der Linde finished fifth and sixth respectively in 2025, but the pair tasted silver and bronze the year before, proving how quickly fortunes can change in open water where tactics ebb and flow.

For Louw, the focus is on sharpening the final surge, the moment where races at Midmar are often won or lost like a perfectly timed kick at the wall.

“Last year I did not finish as well as I wanted to finish,” he admitted.

“I think my last 400 meters last year was a bit of an issue, like I didn’t pick up my kick rate and my stroke rate as much as I should have.”

He knows that at Midmar, execution is everything, from pacing to positioning.

“And just exiting really well is also something I would definitely have to focus on if I want to beat these guys.
At Midmar, some years, the one line is faster than the other line. So you’re definitely going to have a few practice swims to see how well you can execute the race.”

Caldwell recently edged Louw with a cleaner exit during the final seeding swim in Midrand, a detail that could loom large when the dam turns into a boiling cauldron of arms and spray. Confidence, though, flows freely through his camp.

“I’ve been training very hard and the results will show,” he said. “They’ll be good. They’ll be good.”

Beyond the medals and margins, it’s the Midmar magic that keeps drawing him back, year after year.

“Just the people, the experience, just the environment. It’s a very nice weekend away. Nice place, good food, good people, good music. The weekend’s just lovely. I love the racing as well.”

Online entries for the 2026 aQuellé Midmar Mile have now closed. Swimmers still hoping to dive in can enter on the day at Midmar Dam, but are advised to arrive early as places are limited.
