course description
Along the way runners will pass 12 campsites each with stunning huts built in the most secluded areas along the route. There will be 2 aid station each day to assist the runners at road crossings, trails heads, and public campgrounds.
Much of the journey goes through remote wilderness areas, where the rocky trail is a welcomed source of safety. There is a real sense of connection to nature and place. The race will be broken up into four sections each with major aid stations at each completion.
Stage 1 - Starting with the iconic climb up the rock slab from Mount Zero Picnic Area the trail reveals the entirety of the world famous Taipan Wall. After running under the rock wall the trail finds its groove as it toggles between a thin rocky uneven surface and a smooth dirt ribbon. There are numerous waterfalls through here, with continual 360 views of the entire Grampians grandeur, which is a common theme throughout the whole run.
Stage 2 - Halls Gap to Duwul/Mt William has continual long climbs. This section is draining with foot placement and ankle stability being the key. Conserve energy when possible. Take time at Borough Huts to compose yourself and fuel and hydrate. The next 15km to are the hardest along the entire GPT. There is much technical trail, especially up to, and across the Seven Dials and Redmans Bluff. However, the trail improves from here and the views from the top are spectacular as the trail adheres to a clifftop along to Mt William Finish.
Stage 3 - This stage to Griffin Fireline is a net downhill. It starts with a very challenging 19k which crosses the Major Mitchell Plateau up to the high point of the race, Durd Durd at 1167m asl. There is one very steep climb onto the Plateau with big steps - be mentally ready for this. A very long and initially steep descent brings you to Jimmy Creek Rd Aid Station. Many short punchy climbs and flowy downs follow. There is a lot of newly built trail, and it is much appreciated. It will be hard to find rhythm through these shorter continual hills, with some rock hopping, choppy climbs mixed in with fast terrain. There is a very slow boulder field just before Yarram Campground, be careful here.
Stage 4 - Passing over some of the well-known peaks in the southern section of the range, this stage is pound for pound the most scenic section of the trail. The stage starts with a long, gentle climb and descent through some amazing trail and landscape to Cassidys Gap Rd. From here there are three separate steep climbs and descents with many stairs to some striking summits including Signal Peak, Mud-Dadjug/Mt Abrupt, and Wurgarri/Mt Sturgeon. Despite being a brutal end, people will have a sense of the journey’s end, which may bring joy but also sadness that the adventure must come to an end. Runners take an enjoyable river trail to the town centre, where the party celebration awaits!

Evidence for Qualification
This is a relentless and extremely technical race in remote locations. It is critical that you are aware of the challenge that you are committing to. There is no qualification process to enter for the Stage Race, however it is vital that you do not line up to Mount Zero without good preparation and confidence in your ability to stay safe.
At the end of each stage it will be up to our medical team to decide whether it is safe for you to continue the following day. However, it is important that you too make an assessment of your own abilities and recovery before starting each day. You may skip a day and continue the following day.
