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.
Be ready for rain
It rained on 5 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.
General guidance from past years' numbers. Check the forecast in race week.
