Torbjørn Sindballe (born 21 October 1976) is a Danish professional triathlete who was forced to end his competition triathlon career due to heart problems.

Torbjørn Sindballe lives in northern Sjælland with his wife Mette, and their 5-year-old son Oskar.

Thorbjørn Sindballe weighs in at 80 kg and is 190 cm tall, which is an unusual size for an elite triathlete.

To deal with this problem, he has developed, in cooperation with his sponsor Craft of Scandinavia, several methods to endure the heat more effectively: including running in all white, while soaked in water, as well as a glove filled with ice, to cool him down.

Torbjørn Sindballe was forced to announce end to his competitive triathlon career on 30 June 2009, due to a bicuspid aortic valve.
