Kit and pacing
What it means
Warm: adjust your goal pace
Around 22°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.
Be ready for rain
It rained on 3 of the last 10 race mornings. A bin bag or cheap poncho keeps you dry in the start pen; anti-chafe balm and socks that don't hold water help over the distance, and a cap keeps rain out of your eyes.
The weather varies a lot
Race mornings here have ranged by 10°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.
