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 25°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.

  • Humid mornings

    Humidity is usually around 81%, so sweat evaporates slowly and it feels warmer than the thermometer says. Pace on effort, not just the watch.

  • The weather varies a lot

    Race mornings here have ranged by 9°C from year to year. Pack for both, and settle your kit and pacing from the forecast in the last few days.
