MANDATORY GEAR
The Sydney Ultra Marathon 86km course traverses trails where it might take some time for medical and support services to reach you, therefore it is essential that every athlete carry their mandatory gear at all times.
SUM is also a cupless event. Athletes are required to carry their own drinking cup, bottle, flask or hydration vest which can be used at the aid stations.
*The headlamp and high visibility vest is only needed if you intend to take longer than 10 hours to complete the 81km run. The race will start at 7 am with the sun setting at 5:10 pm hence if you’re going to take longer than 10hours you will need a head torch + high vis vest.
**Weather Dependent Items. The race director will make a preliminary call with the medical team 1 week before race day if these additional items are needed. The final call will be made 48 hours before race day.

Suitable Materials:
Thermal garments should be made from polypropylene, polyester, or wool. These materials are ideal because they do not retain moisture and will continue to provide insulation even when damp. The inclusion of materials like spandex or Lycra (up to 6%) is permitted for better fit and flexibility. These materials help in maintaining body temperature by trapping warm air in microscopic pockets within the fabric.
Not Suitable Materials:
Garments made primarily of lycra (a polyester-polyurethane copolymer) and coolmax (a type of polyester designed to absorb moisture) are not suitable for this event. These materials tend to hold moisture close to the skin and facilitate substantial evaporative cooling, which can rapidly lower body temperature in cooler conditions. Additionally, all compression garments, which are predominantly made of lycra, are unsuitable as they do not provide the necessary thermal insulation. Cotton is also inappropriate for thermal wear in this event as it absorbs and retains water, keeping the moisture against your skin. This lack of moisture management can lead to significant heat loss. Cotton's structure fails to trap warm air, thereby increasing the risk of hypothermia in cold conditions. Often referred to as "The Fatal Fabric" or "Killer Cotton" in search and rescue operations, cotton has been linked to numerous hypothermia cases and should be avoided in endurance events where exposure to variable weather conditions is likely

Jackets must have fully taped seams, not just critically taped, to ensure no water ingress. The jacket must also include a hood. The jacket must remain breathable to prevent moisture buildup from perspiration
