About TriSonen
Your triathlon source
Why TriSonen?
TriSonen was founded with a simple vision: to gather all information about Norwegian triathlon in one place. We want to make it easy for athletes, organisers and fans to find race calendars and results.
We have been gathering everything about Norwegian triathlon – races, results and athletes. Now we are starting in Sweden and Denmark. The race calendar and the results database grow continuously as more data comes in.
What TriSonen is for
To make triathlon more accessible by gathering all the relevant information in one place.
For everyone
From beginners to elite athletes — TriSonen is for everyone interested in triathlon.
Passion
TriSonen is driven by a passion for triathlon and a wish to strengthen the sport.

Who is behind TriSonen?
My name is Nikolai Aamaas and I started TriSonen because I wanted a better home for everything triathlon in Norway. The goal is to make all the information easy to find for everyone.
After several years as head coach at Oslo Idrettslag Triatlon and as development manager at the Norwegian Triathlon Federation, I have seen how complex triathlon is and how hard everything is to find. Athletes need one place for the race calendar, results and other useful information — without searching across different websites and social media.
TriSonen is built for the whole triathlon community — from beginners looking for their first race to experienced athletes following results and upcoming races. Together we can make triathlon an even better sport.

How we work
Gathering triathlon results is a big job. Here is a little about how we work and what you can expect.
Importing results
We collect results from different sources, including APIs from organisers and timing systems, as well as Excel and CSV files. Every source has its own format, which has to be processed to fit our database.
AI-assisted mapping
We use AI (artificial intelligence) to map races, find dates and identify where results can be found. This works well in most cases, but can sometimes lead to mistakes in the mapping.
Mistakes can happen
Some data sources, such as the IRONMAN API, contain errors themselves. And the sheer number of races can make it hard to catch every result. We do our best, but rely on feedback from users to correct mistakes. Spotted something that isn’t right? Get in touch and we will fix it!
Our goal for 2026
The goal for 2026 is to have results for every race in the database for the current year. After that we keep adding results from historical races, so you can find all your performances again.
