Ironman Copenhagen 2025

In August 2025 I crossed the finish line at Ironman Copenhagen 140.6 in 11:58:25 — my first full Ironman, three years after picking up a road bike for the first time. Here's how race day actually went.

My experience

Swim: 3.8k swim in the lovely lagoon in salty see water that had on race morning 18.3 degrees. Swim is pretty straight so it’s perfect for people with poor sighting 😀 I was really happy with the time (1h 15min) I swam and came out really confident! 

Swim on Strava

Bike: bike course had in total 1500 meters elevation but had quite some wind on the day. It was scale 4 so nothing worth not putting full disc wheel. Nice rolling and buttery smooth tarmac. My time was 5h 46min. I hoped for 5h 30 to build some buffer for the run where I knew it will be a struggle 😂 

Bike on Strava

Run: phenomenal atmosphere in the city center. Started confident even with fear of back pains that I always get on long runs, this time I felt the back but more issues started at km 20 with stomach issues. I was so fed up with gels that I threw all of them in the trash and picked up crackers and bananas on every station. 

Run on Strava

Overall perfect experience for first time Ironman. Achieved both of my goals. 1st goal was to finish second one within 12hours. My official finish time 11:58:25
