Sebastian Kienle: Background, career highlights, quotes
He was a household name at Ironman 70.3 and long-course victory, but how did Sebastian Kienle get there? Here's what you need to know about the top German's star-studded career...
A three-time Ironman world champion – once at full distance, twice at 70.3 – Sebastian Kienle was a fixture on the Ironman scene for over 10 years.
A key cog in the German domination of long-course racing, here’s how it all began…
Who is Sebastian Kienle?
Sebastian Kienle fell in love with triathlon when he was just eight years old and, despite being of such tender age, immediately knew that becoming a professional triathlete was an overriding career goal. His destiny, almost.
Kienle first started competing in triathlons at the age of 12 and, by the time of he reached his early twenties, he was already a double Xterra champion.
The German’s overwhelmingly strongest discipline is the bike, with his ability on two wheels – often far greater than those around him – being the main reason why Kienle has become so well-decorated in long-course racing.
In 2012, his bike leg set him up for his capturing of the Ironman 70.3 world title in Las Vegas, in the process claiming a course record time. It was a feat he repeated the following year: another world title, another course record.
He wasn’t at all shabby when it came to the full distance either. After a bronze in Kona in 2013, Kienle followed this by grabbing gold in 2014 – his third Ironman world title.
Two more podium finishes in Hawaii followed, along with three Ironman European championships golds and a Challenge Roth title.
He retired from the sport at the end of 2023.
How old is Sebastian Kienle?
Sebastian Kienle was born on 6 July 1984, making him 40 years of age.
Sebastian Kienle’s career highlights
August 2009: A maiden Ironman title, won on home turf
Victory at Ironman 70.3 Germany in Wiesbaden – ahead of compatriot/recently crowned world champ Michael Raelert and Switzerland’s Matthias Hecht – delivers qualification to the world championships. Kienle’s journey towards the top table of long-distance triathlon is gathering pace.
September 2012: Kienle conquers the world, mainly on two wheels
Kienle takes his first Ironman 70.3 world crown in Las Vegas, thanks to an extraordinary bike leg on which he reels in, and powers away from, the leading riders at an extraordinary speed. Indeed, his split is more than five minutes quicker than anyone else.
This helps him to not only have enough of a gap on the half-marathon to hold off Craig Alexander, but to also set a new course record in the desert of 3:54:53.
October 2012: Just outside the medals in Kona
A month later, Kienle goes long at the Ironman worlds in Kona and, after suffering from a puncture, finishes fourth, behind the Australian Pete Jacobs, Germany’s Andreas Raelert and the Belgian Frederik Van Lierde.
September 2013: Kienle remains 70.3 world champion
A successful defence of his Ironman 70.3 world title in Las Vegas, the final year of the event being in Nevada. And it’s another course record, shaving 33 seconds of his winning time of 12 months earlier.
October 2013: Bronze in Kona shows upward progression
Kienle improves on his previous best in Kona, making the podium this time around, behind Van Lierde and the Australian Luke McKenzie. In McKenzie, the German meets a rare beast: someone who can go as fast – a little faster today, actually – than he himself can.
July 2014: The new thirty-something is the king of Europe
One day into his thirties, Kienle takes his first Ironman European champion title in Frankfurt, demolishing the course record, helped – of course – by a bike leg that’s more than eight minutes inside the previous best split.
October 2014: A third world title – this time it’s the big one
Three months later in Kona, Kienle takes his first – and, to date, only – full-distance Ironman crown. The margin of victory over the silver medallist, the USA’s Ben Hoffman, is a comfortable five minutes, and one largely due to yet another storming bike leg that sees him take a full ten minutes out of the next-fastest rider. Fellow German Jan Frodeno completes the medallists.
October 2016: Kienle bags the full set of Kona medals
Having finished a disappointment eighth when attempting to defend his world title in 2015, Kienle returns to the podium a year later when he takes silver. Joined on the podium by Frodeno and Patrick Lange, it’s a German 1-2-3.
July 2017: A third European Ironman crown
After a second victory in 2016, Kienle makes it a hat-trick of titles at the Ironman European championships in Frankfurt.
July 2018: Kienle takes his maiden victory at Challenge Roth
Despite not posting the fastest bike split at the 2018 edition of Challenge Roth (that honour went to Australia’s Cameron Wurf, who set a new record for the leg), Kienle pulls back the two-minute margin separating them within the first 5km of the run, after which his maiden victory in his homeland event is assured.
October 2019: A fourth top-three finish in Hawaii
Showing that there’s still life in the old dog’s legs, Kienle claims his fourth appearance on the Kona podium, coming home in the wake of Frodeno and the USA’s Tim O’Donnell.
May 2022: Top-15 in the Ironman Worlds
Goes into the postponed 2021 Ironman World Champs as the only former world champion, and finishes 14th.
October 2022: A superb sixth in Kona
In his ninth and final Ironman World Championship outing, he finishes inside the top 10 in sixth place with his fastest-time ever on the Big Island. It’s a fitting farewell for one of the most decorated male triathletes in the sport.
2023: The farewell world tour
In his self-titled ‘farewell world tour’ he spends 2023 racing some new and some not-so-new courses before hanging up his twi-suit. Highlights include a third at Challenge Wanaka Half, a fourth at Ironman New Zealand, a win at the Zarauzko Triathlon and a fourth at Ironman Cozumel, his last-ever race as a pro.
Sebastian Kienle in quotes
On the magic of triathlon: “When looking at the 100-metre sprint, it’s only about time, or winning or losing the race. You never have the feeling of accomplishing something when you have the finished it.”
On winning Kona in 2014: “If you believe you have won the race too early, then you are probably going to lose it. It’s all about holding back and not letting any emotion get to you. Then at the finish line you can let it go.”
On how fatherhood has affected his triathlon career: “Now it’s hard for me to travel, even for a few days. But it’s a great motivator. In the past, I needed an hour to get ready for training. Now I do it in five minutes.”
On his final Kona performance in October 2022: “I think it was a really good race for me but it shows how deep the field is and the huge talent that is coming up. It’s time to hand over to the next generation. I’ve no regrets and I’m happy with my career and will enjoy this last year as much as I can.”
What’s next for Sebastian Kienle?
In 2024, Kienle has been racing Hyrox and trying a spot of gravel riding.
