About
About Triathlon Atlas
An independent directory of long-distance triathlon races, built to be filtered and compared.
What the site does
Triathlon Atlas holds 159 races from the organiser's published calendar, each with the fields that can be read on the organiser's own pages and the date they were read. The finder crosses those fields, the comparator puts races on the same rows, and each race page places the race among all the others of its distance.
Where a field is not published, the site says so and leaves it empty. That rule shapes every page, and it is the reason the coverage table appears on so many of them.
No affiliation with the organiser
Triathlon Atlas is not affiliated with, endorsed by or sponsored by IRONMAN or World Triathlon Corporation. Race names are used only to identify the events they name. The site sells no entries, carries no advertising and uses no affiliate links.
Questions about the site
Why only one organiser?
Its calendar is published in a consistent form for every race, which makes the fields comparable. Other races can be added when their data can be read with the same care.
How are the figures kept up to date?
Each record is read again on a schedule, oldest reading first, and every value carries its reading date. The method page gives the detail.
Can I suggest a correction?
Yes. The contact page takes reports of wrong or missing figures, and each one is checked against the official page.
Is the site available in other languages?
In English, French and Spanish. The language links in the header open the same page in the other language.
