Jelle Geens has admitted he will need to be “a lot better” if he is to make history at the IRONMAN 70.3 World Championship after a revealing return to racing in Austria.

The Belgian superstar is bidding to become the first man to win the 70.3 world title for three successive years when he lines up in Nice in just a fortnight’s time.

But Geens was brutally honest about where his current performance level would leave him after finishing second behind an outstanding Lasse Nygaard Priester at IRONMAN 70.3 Zell am See-Kaprun.

Asked what Sunday’s display might mean for his prospects in Nice, the reigning champion replied: “I will need to be a lot better in two weeks.

“I think this race performance might get me in the top 20. I don’t know, maybe not even that.”

Geens makes long-awaited return

There was, however, plenty of important context surrounding Geens’ performance.

This was his first race for 134 days, dating back to a DNF on his full-distance debut at IRONMAN Texas in April.

Geens had gone into 2026 with the IRONMAN World Championship in Kona as his major target, but those plans were ultimately derailed by a Grade 2 femoral shaft stress reaction which forced him to stop running.

He eventually shelved his Kona qualification bid rather than risk compromising his recovery and instead switched his complete focus to Nice and the opportunity to complete an unprecedented hat-trick of 70.3 world titles after seeing off Hayden Wilde and Kristian Blummenfelt in epic editions in 2024 and 2025.

That made Zell am See a particularly important test – his first opportunity in more than four months to discover exactly where he stood in race conditions.

And viewed purely from the outside, much of what Geens produced was encouraging.

He emerged from the swim just 19 seconds off the front before helping to rip the race apart on the biggest climb of the bike course.

Geens and Priester moved clear of their rivals and arrived at T2 together with more than two minutes in hand over the chasing pack, setting up what appeared to be a mouthwatering running showdown between two of the quickest athletes in the sport.

But Geens revealed afterwards that things hadn’t felt nearly as comfortable as they looked.

“Yeah, it was quite tough,” he explained.

“I felt I was struggling to keep the pace a bit.

“But I guess it’s expected after not racing since April.”

‘I was not the freshest’

Perhaps most revealingly, Geens said his problems weren’t restricted to the run.

He had looked powerful on the bike, particularly on the main climb where he and Priester established their decisive advantage, but maintaining that effort proved much harder.

“Also the bike, to be honest,” he said when asked where he had struggled most.

“I felt quite good on the climb but I was struggling to keep the pace.

“That whole last hour on the bike, I was happy Lasse was there to help push the pace because I was not the freshest there.”

The difference became much more obvious as soon as they started running.

Priester had briefly been forced to turn back after dropping his visor leaving T2, but wasted little time putting the hammer down once he got going.

The German had opened a 30-second advantage inside the first 3km and was more than two minutes clear by halfway.

Geens admitted he initially tried to go with him before quickly realising that wasn’t sustainable.

“On the run, I tried to follow him for the first bit but I could feel quite straight away that I had to settle for a not-so-fast pace.”

Priester went on to smash the course record with his winning time of 3:43:29, leaving Geens more than two minutes adrift.

So there is another important consideration when assessing the reigning world champion’s performance: Geens may have been below his best, but he may also simply have run into a very good winner.

Can Geens turn it around for Nice?

The obvious concern is that Geens has very little time to find the improvement he believes he needs.

Nice is just two weeks away and the field awaiting him there will represent a significant step up in depth as he attempts to defend those titles he won in 2024 and 2025.

But Geens says he still has hope.

He revealed that he had arrived at Zell am See carrying considerable fatigue from his preparations and believes freshening up over the next fortnight could make a significant difference.

“I think now I need to really freshen up,” he explained.

“I did quite a big training block leading into this race, so definitely missing that freshness.

“And I hope with two weeks of easier training, with maybe a little bit of intensity, and getting that freshness back, [I’ll be able] to keep the pace.”

That leaves one of the biggest questions heading into the men’s showdown in Nice.

Geens knows the performance he produced in Austria won’t be enough to win a third successive world crown – indeed, by his own estimation it might not even put him inside the top 20.

But after five months without racing, an injury-disrupted season and a heavy training block immediately before his comeback, there are plenty of reasons to believe there is more to come.

The question is whether two weeks is enough time for the reigning world champion to find it.
