THE STORY

01

It began in Kalmar.

Long before entering a race, I watched athletes cross an IRONMAN finish line in Sweden. I wasn’t doing endurance sports then. The atmosphere stayed with me, and so did the idea of one day trying it myself.

02

One year to learn.

Training started in September 2025. Swimming was the hardest beginning: 25 metres and I was out of breath. Over the following months came the first continuous 2-kilometre swim, a marathon in Lausanne, and a roughly 180-kilometre ride around Lake Geneva. Progress also meant learning about injuries and recovery.

03

Three disciplines. One finish.

On 6 September 2026, the distances became real: 1.9 kilometres in the water, 90 kilometres on the bike, then a half marathon. The official splits were 41:14, 2:31:07 and 1:51:13. With the transitions, the clock stopped at 5:13:25.

04

A finish, and a beginning.

When I began, finishing within the time limits was the ambition. Finishing under 5 hours 15 opened a different perspective. The next objectives are a full-distance IRONMAN in Les Sables-d’Olonne and a 70.3 in Nice in 2027.
