Kit and pacing
What it means
Warm: adjust your goal pace
Around 27°C on race morning costs most runners time. Plan to run a few seconds per kilometer slower than in cool weather, take on fluid and salt at every station, and wear light colors and sun cream.
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 25 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.
