100km / 50km Additional Cold & Wet Mandatory Gear: NOT MANDATORY

The weather forecast for the weekend looks good so the following items are not mandatory for the distances specified:

  • Waterproof Pants (100km)
  • Fleece (100km)
  • Waterproof Jacket (50km)

Review: 100km Mandatory Gear | 50km Mandatory Gear

Fleece highly recommended (100km)

Temperatures are expected to average around 7°C overnight but could be colder in some of the more remote areas of the course and in creek valleys.

Runners who expect to be moving slowly through the night may wish to carry a fleece to stay warm. This may be collected from a drop bag at a checkpoint, eg. CP4 Lake Manchester.
