SUM exists to prove something simple, that Sydney, one of the world’s biggest cities, still has deep, wild bushland on its doorstep.
The Sydney Trail Marathon 42km 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.
STM 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.
Mandatory Gear
Some text here describing the FAQ’s section of the home page.

The bandage is required as you might need to use it treat sprains or potential snake bites. We recommend this snake bandage from Amazon.
-
This can be in the form of 2 × 500ml running flasks, a bladder or normal water bottles.
Please note that STM is a cupless event.
