What this atlas holds

races
159 Every event on the organiser's calendar on 22 September 2026: 111 half distance, 41 full distance and 7 short course.
countries
45 Across seven regions. Europe 53, North America 39, Latin America 30.
degrees of water
14–29 The published average, coldest to warmest. 148 races give one, and the other 11 are shown as giving none.
filterable fields
26 Every criterion the comparator can sort on has its own indexed column, including the ones the organiser publishes for only a handful of races.

Method

Where these figures come from

Every value here was read from the organiser's own pages on 22 September 2026. The listing gave the name, the date, the country and the three course labels. Each race's own page gave the average water temperature and the high and low air temperatures. Each course page was read in full, and the few figures its prose states were checked by hand before being kept: a bike elevation for 10 races, an overall cut-off for 4, a swim start type for 25.

Nothing was estimated and nothing was carried over from a previous year. Where a page publishes no value the field stays empty and is shown as empty, which is the case for most elevations and cut-offs, and for every entry fee and qualifying slot count.
