Kit and pacing

What it means

  • Good racing weather

    Around 10°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.

  • It can be cold

    The coolest morning here dropped to 1°C. Pack gloves and a throwaway layer even if the forecast looks kind.

  • 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.

  • Expect wind

    Wind was 21 km/h on a typical morning here. Run in a group on exposed stretches, and aim for even effort rather than even splits: time lost into a headwind isn't all won back with it behind you.

  • The weather varies a lot

    Race mornings here have ranged by 11°C from year to year. Pack for both, and settle your kit and pacing from the forecast in the last few days.
