Safety
For this event you need to take responsibility for your own safety. You need to know what is going on. DO NOT turn up saying – ‘I wonder where we are going today’ or ‘Hills??!! No one told me there were hills in this race’ or my all-time favourite: ‘Bus? What bus? I was just going to take an Uber to the start’.
Each day involves challenging terrains including hills and overgrown single tracks. Don’t gauge your run time by distance alone. Snake Gully (5km) on Thursday and Vivier’s Track (6km) on Friday will take much longer than expected. Be prepared for obstacles such as fallen trees, branches, washed out sections, snakes and orb spiders. Watch the videos we’ve posted on Facebook when we’ve been out there in 2025 setting out the markers.
TAKE NOTE! Tap water is only available at the checkpoints. There will be extended periods where you will not have access to tap water. If you intend to fill up at creeks, you must have your own purification method in place to deal with this. On Saturday we will put water out along Lake Morris Road, approximately every three kilometres.
Don’t race if you are injured or sick
This event is for experienced trail runners. Familiarise yourself with the route, course descriptions and safety precautions. Arrive prepared to avoid any surprises in terms of race conditions or logistics. Be very mindful and alert on the trails. Help your fellow competitors.
