Kit and pacing

What it means

  • Mild: start a touch conservatively

    Around 16°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 28°C by late morning. Decide in advance how much you'd slow down if the forecast is warm, rather than on the course.

  • 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.
