How to read these numbers
- ERA5 gives daytime highs about 1–2.5 °C below nearby weather stations, so on warm race days runners felt more heat than the numbers here show; we do not correct for this.
- Edition window: the race day; 9:00 local time is taken as the typical start.
- Dates of past editions: Wikidata and Wikipedia (de, en, fr, nl, pt, sv); cancelled editions (e.g. 2020–21) are not counted.
