A press release states that Danish pro triathlete Torbjørn Sindballe has retired from triathlon, effective immediately. We will follow with more detail on this shortly, but will leave the early details to the attached press release that Sindballe, a man known for his exceptional bike prowess, sent Triathlete this evening.


During Wildflower Triathlon in early May the Danish powerhouse ended his race hyperventilating in T2 after a very uncharacteristic bike ride, during which he faded down the field with a drastically dropping heart rate and heavy fatigue. The Dane has known about an abnormal heart valve since 2005 and has had regular checkups to ensure he was safe to race. After the incident in California, he has gone through extensive testing and evaluation with Danish experts. After considering their advice, Torbjørn Sindballe has decided to stop his career immediately.

“The past months have been an emotional rollercoaster for my family and I,” Sindballe said. “Going from world-class competition in the toughest sport in the world to fearing a heart surgery in the near future at the same time as your second child is born is an extreme experience. My wife, family, friends and sponsors have been a tremendous support in this process and the doctors have been outstanding in their evaluations. Based on the situation, I feel good about the decision and can look back on an amazing career in an amazing sport.

“I am going to miss the lifestyle and the intense excitement of training and racing,” he adds. “Of course I’m sad that I will not get to see the impact of the big changes in my training we have made this year and that I will not be able to compete for the crown in Kona. On the other hand I am very proud of what I have achieved. Two ITU Long distance World Champs and a podium in Kona, where I am really not suited to race, is something I will carry with me forever. I have learnt so much and feel very privileged.

Sindballe continues: “There are so many people who have devoted their expertise, insight and inspiration to me and to them I will be forever thankful. I have met countless truly amazing people in this sport and will never forget the time I have had with them. So many people have inspired me in my career and I hope I can give back in the coming years, helping people realize their dreams in sport, family and worklife.”

Facts on Bicuspid Aortic Valve

Torbjørn Sindballe has what is called a bicuspid aortic valve. This is the most common heart malformation found in 1-2 percent of the population. It means that instead of three claps there are only two claps in the aortic valve that make sure blood is directed from the heart to the body and not the other way around. Most people with this malformation live their entire lives without ever knowing about it.  In some cases complications develop including a tightening or a leak in the valve. The tissue in aorta can also be affected so that there is a abnormal dilation of the main artery.

Torbjørn has a moderate leak, which means that 20 percent of the blood returns to the heart for each heartbeat. During work the leak drops to about 5-7 percent, which means that Torbjørn has competed with a marked reduction in his capacity for many years. It is possible that further hard training and racing would increase the risk of progression so that heart valve replacement would be needed in the near future. Torbjørn’s aorta is moderately dilated, which markedly increases the risk of dissection under heavy workloads.
