Kit and pacing
What it means
Warm: adjust your goal pace
Around 20°C on race morning costs most runners time. Plan to run a few seconds per kilometer slower than in cool weather, take on fluid and salt at every station, and wear light colors and sun cream.
Humid mornings
Humidity is usually around 80%, so sweat evaporates slowly and it feels warmer than the thermometer says. Pace on effort, not just the watch.
The weather varies a lot
Race mornings here have ranged by 9°C from year to year. Pack for both, and settle your kit and pacing from the forecast in the last few days.
General guidance from past years' numbers. Check the forecast in race week.
