Challenge Roth: A Magical Day, A New World Record
A crowd of 300,000 witnessed Sam Laidlow rewrite the long-distance record book, while Alanis Siffert announced herself with the biggest victory of her career.
Challenge Roth
There is simply no way to understand the scale of Challenge Roth without experiencing it in person.
Race Director Felix Walchshöfer told us exactly that in our recent interview, and after spending race week on the ground, I can say he was absolutely right. Whether you’re a long-distance triathlete or not, Roth belongs on your bucket list. Around 300,000 people descended on the region this year, with enormous crowds lining the course and taking part in the week-long festival, many without ever pinning on a race number.
And if you are a long-distance athlete? The fact that entries sell out in well under a minute, and that the on-site queue for next year’s race already stretched roughly 1500m this morning, tells you everything you need to know about how special this event is.
There is truly nothing else like it in the sport.
A New World Record on a Magical Course
Beyond the unmatched atmosphere, this year’s edition of Challenge Roth delivered a performance for the history books as Sam Laidlow took the victory with a new long-distance world best time of 7:21:04.
This eclipsed Magnus Ditlev’s previous fastest-ever time of 7:23:24 set on this course in 2024. Laidlow’s performance also bettered Kristian Blummenfelt’s 7:21:24 from Ironman Texas as well as the 7:21:12 Blummenfelt previously recorded in Cozumel – a mark that was long-disputed as a potential world record but with an asterisk beside it.
As Walchshöfer put it during the post-race press conference, there has been plenty of debate in recent years about what truly constituted the men’s long-distance world best time. But Sam Laidlow settled that debate here in Roth.
The race itself had fans in suspense from start to finish. Rico Bogen exited the water first, with Laidlow close behind. It was Bogen’s full-distance debut, and there was plenty of intrigue surrounding the young German (and 2023 Ironman 70.3 World Champion) as he stepped up to the full distance.
Bogen remained at the front throughout the bike, cresting the iconic Solar Hill first before entering T2 just ahead of Laidlow. Together, the pair had opened a substantial gap over the rest of the field, while pre-race favourite Kristian Blummenfelt found himself more than 12 minutes behind by the start of the marathon, a deficit few expected.
Once onto the run, Laidlow finally made his move, pulling clear of Bogen and looking poised to take the win. But in the closing stages of the run, his pace began to fade, and the pain was etched across his face over the final quarter of the marathon.
Laidlow has built his career on racing without compromise. It is the fearless, all-in approach that carried him to the 2023 Ironman World Championship in Nice, but it has also led to spectacular blow-ups, most notably after his record-setting bike split at Kona in 2024. The question became: could he hold on for the win?
And he did, crossing the finish line in a historic 7:21:04. The emotion was unmistakable as he embraced Walchshöfer at the finish line.
Blummenfelt ran his way to second place, while Bogen took third, recording the fastest-ever full-distance time on debut with a remarkable 7:27:53.
Alanis Siffert’s Breakthrough
On the women’s side, as expected, Lucy Charles-Barclay – who had confirmed her participation just days before the race – led the field out of the water in 50:23. But the race quickly took an unexpected turn.
By the time the athletes reached the iconic Solar Hill, Swiss athlete Alanis Siffert had ridden herself into the lead, with Caroline Pohle in second, Charles-Barclay in third, and pre-race favourite Kat Matthews losing ground after an uncharacteristically difficult start to her day.
With Matthews off the pace and Charles-Barclay still working her way back to full fitness following surgery earlier this year, the women’s race suddenly looked wide open. Siffert seized the opportunity.
In the post-race press conference, the 23-year-old revealed she deliberately covered the power numbers on her bike computer and stopped looking at her run pace because she knew she was producing numbers she had never sustained before. Rather than backing off, she chose to trust how she felt, commit fully, and see what was possible.
It proved to be the race of her life. Siffert crossed the finish line in 8:09:09 to claim the biggest victory of her career, improving on the third-place finish she recorded in Roth just one year ago by more than 30 minutes.
Charles-Barclay finished second in an encouraging return to racing as she continues building toward the Ironman World Championship events in Nice and Kona later this season, while Daisy Davies completed the podium with an impressive third-place performance.
