About
About Triathlon Atlas
An independent directory of triathlon races, built to be filtered and compared.

What the site does
Triathlon Atlas holds 354 races, each with its date, place, swim, course profile and race-day conditions. 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 the figures come from
Dates, distances and entry status come from each organiser’s official race page. Course figures (elevation, cut-off, swim start) come from the organiser’s pages and athlete guides, and, when they publish none, from a named source such as a recorded course file or a climate normal for air temperature. A field that no source publishes is left empty rather than estimated.
Every race is re-read regularly against its official page; the most recent reading is dated 8 November 2026. To report a wrong or missing figure, use the contact page.
No affiliation with the organiser
Triathlon Atlas is not affiliated with, endorsed by or sponsored by any race organiser or circuit, including IRONMAN, World Triathlon Corporation, Challenge Family, XTERRA, the PTO (T100), Clash Endurance and XTRI. Race names are used only to identify the events they name. The site sells no entries and carries no advertising. The map of places to stay on each race page is provided by Stay22, and the site may earn a commission on a booking made through it, at no cost to you.
