Kit and pacing

What it means

  • Dress for the cold start

    Mornings are usually around 1°C. Gloves, a hat and an old top you can throw away at the start are worth packing, and warm up for longer than usual: cold muscles take a few kilometers to get going.

  • The weather varies a lot

    Race mornings here have ranged by 19°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.
