Germany’s Lasse Nygaard Priester showed he is a real contender for the IRONMAN 70.3 World Championships in a fortnight’s time by blazing to an impressive victory over Jelle Geens at 70.3 Zell am See-Kaprun in the stunning Austrian Alps.
Belgian star Geens is going for an unprecedented (in terms of the men) third successive 70.3 Worlds title but he had no answer here to rising star Priester.
Priester told TRI247 in an in-depth interview a couple of months ago that the 70.3 Worlds in Nice was his big target this season and this couldn’t have been a better advert for his chances.
He was right in the mix in the swim before breaking clear with Geens on the bike and the two of them looked set to duke it out on the run.
But such was Priester’s early pace that he was soon clear and he won unthreatened by over two minutes in a new course record time, with Tjebbe Kaindl (AUT) a distant third.

This was the last ‘regular season’ IRONMAN Pro Series race and here’s how it played out…
Swim – favourites to the fore
The picture-postcard setting of Zell am See-Kaprun provided the backdrop for a true Alpine adventure on one of the most spectacular courses on the IRONMAN roster.
It began with a single-loop, out-and-back 1.9km swim in the crystal-clear waters of Lake Zell, with calm conditions greeting the athletes.
It was a good, clean start and remarkably little separated the leading contenders, with just 23 seconds covering the first 12 men as they emerged from the water in one long line.
Home favourite Kaindl led the way in 23:07, but virtually all the big pre-race names were right there.
Defending champion Fabian Kraft (GER) was third at +6 seconds, Valdemar Solok (DEN) fourth at +10, Priester sixth at +15 and Geens ninth at +19.
Further back, two of the strongest cyclists in the field already had some work to do, with Australia’s Cam Wurf 55 seconds down and American Trevor Foley at +1:22.
Bike – Geens and Priester break clear
Kaindl flew through transition and, to the delight of the home crowd, started the 90.1km bike leg alone with a 15-second advantage.
That gave the Austrian the luxury of getting out of town without having to worry about the traffic behind him.
It was a very different story for Damien Le Mesnager (FRA), who had emerged from the water more than two minutes behind and then saw that deficit almost double following a mechanical issue before he had even escaped transition.
The opening 21km were predominantly flat and downhill and, once the race settled down, Kaindl’s rapid transition had helped him establish himself in an elite five-man group alongside Priester, Solok, Geens and Kraft.
And they weren’t hanging around, already holding an advantage of almost a minute-and-a-half over the rest of the field.
But the defining section of the bike was always likely to be the course’s major climb between kilometres 21 and 35 – and that was where Geens began to turn the screw.
The Belgian put down the power and the five became two as he and Priester broke away.
By the top of the climb they had put almost a minute into Solok, Kraft and Kaindl, leaving 55km of predominantly downhill and flat riding between themselves and T2.
It had effectively become a two-man time trial – and Geens and Priester continued to dominate.
With 30km remaining they were nearly two minutes ahead of the chasing trio, while neither Foley nor Wurf was making significant inroads from further back. Foley remained more than four minutes adrift and Wurf was at +4:45.
The advantage remained steady through the 72km checkpoint and the leading pair eventually arrived back at T2 with a commanding cushion.
Gregor Payet (LUX) had worked his way into third but was 2:26 behind, while Foley had produced a strong late surge to jump to fourth at +2:50.
And now came the mouthwatering prospect: two of the fastest runners in middle-distance triathlon starting the half marathon virtually shoulder to shoulder.
Run – Priester puts on a show
Priester reached T2 fractionally ahead and, despite briefly having to turn back for a dropped visor, was first onto the run course.
There was virtually nothing between the two men as they started the flat, crushed-gravel 21.1km route around Lake Zell.
That didn’t last long.
Priester immediately put the hammer down and the damage he inflicted on the reigning two-time world champion was remarkable.
Inside the opening 3km, the German had already taken 30 seconds out of Geens.
And instead of paying for that aggressive start, Priester continued to stretch his advantage.
By halfway he was more than two minutes clear and on course for an astonishing run split, particularly given that much of the route was on crushed gravel rather than tarmac.
The temperature was rising and Priester did slow slightly during the closing stages, but by then the victory was beyond doubt.
He completed the half marathon in a brilliant 1:10:58 to cross the line in 3:43:29, breaking the previous course record by a little over a minute.
Geens followed him home more than two minutes later, while Kaindl ensured there was something for the Austrian crowd to celebrate by taking third.
But with Nice now just two weeks away, it was Priester who delivered the biggest statement.
The German had already made the 70.3 World Championship the centrepiece of his season. On this evidence, the defending champion and the rest of the world’s best will have another major contender to worry about on the Côte d’Azur.
