Kit and pacing
What it means
Mild: start a touch conservatively
Around 14°C feels fine at the start but warms up by the second half. Drink from the early stations rather than waiting until you're thirsty, and wear the lightest kit you have.
Have a warm-day plan
In the warmest of these years it reached 23°C by late morning. Decide in advance how much you'd slow down if the forecast is warm, rather than on the course.
General guidance from past years' numbers. Check the forecast in race week.
