Kit and pacing
What it means
Good racing weather
Around 5°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.
Have a warm-day plan
In the warmest of these years it reached 20°C by late morning. Decide in advance how much you'd slow down if the forecast is warm, rather than on the course.
It can be cold
The coolest morning here dropped to -6°C. Pack gloves and a throwaway layer even if the forecast looks kind.
The weather varies a lot
Race mornings here have ranged by 23°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.
