Biography
Sebastian Aldén built his first career on pure, explosive power, racing 500cc speedway bikes in the slick corners of European tracks. As a professional speedway rider, he competed in the Swedish and British leagues, known for his aggressive style. In a dramatic mid-life pivot, he channeled that athletic intensity into an entirely different arena: Ironman triathlon. After retiring from speedway, Aldén dedicated himself to the punishing discipline of swimming, cycling, and marathon running. His transformation from power athlete to endurance machine is remarkable, culminating in his qualification as a professional triathlete. He now competes in full-distance Ironman events, proving that the competitive fire forged on the speedway track can fuel a successful second act in one of the world's most demanding sports.
Millennials
1981–1996
The first digital natives. Grew up with the internet, came of age during 9/11 and the 2008 crash. Highly educated, deeply indebted, slower to marry and buy houses. Redefined work, identity, and what it means to be an adult.
Sebastian was born in 1985, placing them squarely in the Millennials. The events that shaped this generation — the internet revolution, 9/11, and the 2008 financial crisis — shaped the world they entered and the choices available to them.
