When Arthur Horseau stood on the start line at IRONMAN Cozumel on Sunday that was a victory in itself.
For he hadn’t raced professionally since a DNF at the IRONMAN World Championship in Kona in 2024, a far cry from the previous year when he was sixth at the IMWC on home roads in Nice, behind his great friend and training partner Sam Laidlow.
A succession of issues – most notably a back problem – had frustrated Horseau for much of this year, leading him to question what his future in the sport held.
In the middle of this year, he wrote: “A few months ago, I wrote that I didn’t know when I’d be racing again. I had just gone through a tough time – injury, loss of support, doubts… and that feeling that everything was falling apart, little by little.”
‘The drive is coming back’
But then a significant step forward as the underlying causes of the back pain were addressed and things started to look up.
“Now, the drive is coming back,” he said. “I’m easing back into training – with more calm, more clarity, and one clear goal: to prepare for an Ironman at the end of the year. Not to prove anything. Not to forget. Just to move forward. Thank you to those who stood by me during the lows.”
That IRONMAN at the end of the year was Cozumel in Mexico on Sunday and what unfolded there was fairytale stuff for Horseau as he took the lead around 10km into the run and moved clear of his rivals for his first success since 2023 – in the process booking a return to Kona in 2026.
He was wearing bib number 42, an indication of how far he’d slipped down the rankings.

‘Never give up’
So no wonder the emotions were flowing in his post-race debrief on Instagram: “IRONMAN Cozumel – Champion 🏆 I still can’t quite believe it as I’m writing these words.
“These past months, I hit rock bottom. I doubted myself, I stopped believing, and I questioned everything.
“And while I was losing my way, some people kept believing in me. They supported me, lifted me up, and gradually helped me rediscover what I love.
“Today, above all, I feel proud. Proud of pushing myself to the very end. Proud of holding on, moving forward, and ultimately winning this victory.
“This victory isn’t just mine. It belongs to everyone who has fallen, but found the strength to get back up and keep fighting. Never give up. 🔥💪”
A perfect way to end the year then for Horseau and the likes of Jan Frodeno and Laidlow were among those quick to offer their congratulations.
