MANDATORY GEAR

The Sydney Ultra Marathon 50km 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 51km 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.
