Competitors are expected to be self sufficient and to carry mandatory kit that includes a charged mobile phone, waterproof jacket, emergency foil blanket and a bag or pack to carry these items. Organisers do not provide bottled water or disposable cups; runners must carry refillable containers. A drop bag option is available at the turnaround for the ultra.
