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.
- No dates found for 2016, 2022, 2023, 2024: these editions are not counted.
- Dates of past editions: Wikidata and Wikipedia (de, en, es, fr, it, pl); cancelled editions (e.g. 2020–21) are not counted.
