Race morning ran warmer than forecast27 September 2026
Observed, Berlin Brandenburg airportForecast the day beforeFinishers in 3h30 to 5h00It ran up to 2°C warmer than the forecast the day before. The day warmed 11°C between the first start and the late finishes, so the second half was the warm half. Holding effort steady and letting pace drift late suited the day better than even pace from the gun.
Observed: hourly reports from the Berlin Brandenburg airport (EDDB) weather station, about 19 km from the start. Forecast: city forecast as issued the day before the race. W1 to W6 mark wave starts (08:45, 09:05, 09:33, 10:02, 10:12, 10:27). Not official race measurements.
