Kit and pacing
What it means
Good racing weather
Around 6°C is close to ideal for a fast time. Shorts and a vest are enough once you're moving; bring a throwaway layer for the wait in the start pen.
It can be cold
The coolest morning here dropped to -2°C. Pack gloves and a throwaway layer even if the forecast looks kind.
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.
Expect wind
Wind was 25 km/h on a typical morning here. Run in a group on exposed stretches, and aim for even effort rather than even splits: time lost into a headwind isn't all won back with it behind you.
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.
