231km – Redbank Gorge, up Mt Sonder and back, then East along the Rugged and Spectacular Larapinta Trail through to the Telegraph Station in Alice Springs

Brought to you by Alice Springs Running and Walking Club, the West Macs Monster (WMM) is the iconic and formidable end to end Larapinta Trail race you’ve been waiting for! 231kms of spectacular and rugged single track affectionately named the ‘Sonder Monster’ that winds itself through the ancient West MacDonnell (Tjoritja) Ranges landscape in Central Australia. The course provides an intimidating, yet alluring test of physical and mental endurance in a non-stop, end to end race format with a 60 hour cut-off. Only a handful of individuals have ever attempted and succeeded at completing the full trail distance in under 60 hours with the current fastest known time of 40 hours 55 minutes 18 seconds set at the West Macs Monster in May 2019 by Shane Johnstone from Western Australia.

Whether it be an awesome Solo effort or Teams or 2 or 4 members, you are in for an unbelievable adventure race!

Start with a climb they said….it will be fun they said…..

Well a climb it is! 8km and ~740m of elevation gain just to get the heart rate going – to the top of Mt Sonder with the most amazing 360° panoramic vista. This climb sets the scene for the remainder of this amazing trail, that is the iconic Larapinta Trail in the Northern Territory. Those keen to enter the full 231km Sonder Monster will be rewarded time after time after time with vistas beyond belief. From here you descend the same path and at the base of the mountain, turn to the east and head towards Alice Springs. Some running relief for a while with beautifully formed undulating single track taking you to your first water stop – Rocky Bar Gap. Beyond here you will ascend to a lookout where you can relive your Mt Sonder visit…by looking back and enjoying a most stunning image of the mountain, filling your field of view.

Eastwards you continue through  to the stunning Ormiston Gorge and the second aid station. Then more fantastic single track rolling through spinifex hills and climbs to more ridge lines as darkness descends! Make no mistake, this trail has many technical elements and at times some navigation is required following the Larapinta Trail blue triangles (which are reflective at night). But you will be following in the footsteps of thousands of people who traverse this track every year. No doubt you will encounter many walkers who will be blown away by your ambition to run the whole trail.

The approach into Ellery Creek Check point will most likely be in the dark and a warm welcoming light awaits. From here you will head generally North East and across the longest single stage of the Larapinta Trail into the depths of the Chewings Range at Hugh Gorge. Here the course starts to cover some of the more challenging terrain, with travel up Hugh Gorge, over Razorback Ridge, through Spencer Gorge and up the magnificent Brinkleys Bluff past ancient cycads and waterholes and then to the Standley Chasm checkpoint. Trail markers are reflective and show up well in your lights. The markers provide regular confidence checks, but it will still be necessary to keep your fatigued wits about you in the night sections.

The Ellery Monster 128km competitors commence their eastward journey at 12pm on Saturday. It is anticipated that you will all integrate together over the next 128km to the finish line at some point.

Beyond the Standley Chasm checkpoint you will go into the most amazing back canyon, with rocky technical sections and views up and down rugged ancient valleys full of Ghost Gums, Cycads Palms, Mulga Trees and spinifex. You will reach Millers Flat where you need to turn left and climb the high route option. The climb up this hill will test your weary legs, but is the first of three significant climbs to go. It is possibly the most spectacular and technical of all the climbs. Again, don’t forget to take some priceless selfies on top of this ridge (if you are lucky enough to be there during the day).

The 65km Standley Monster runners start at 6am on Sunday Morning from the Standley Chasm checkpoint. It is likely you may well encounter them as well from here to the finish line.

Off this hill, through fish hole waterhole and continuing to Mulga Camp – a well deserved check point, restock your fluids and eat some food. This signifies the end of the real hard stuff, with only two mild climbs in comparison to come. Easier running is your experience now through to Simpsons Gap checkpoint. From Simpsons Gap, 25km of fantastic running until the finish line.

The 25km Simpsons Monster Competitors start their journey at 12pm on Sunday. There is a chance you will come across them, or they may come across you as you make your way over the last section into the Alice Springs Telegraph Station. Compared to what you have endured so far, the ups and downs of this section pale into insignificance – however – you will be on weary legs well and truly so don’t be fooled! The last few kilometers takes you over Euro ridge, regarded as the best view of Alice Springs from the Trail and then, finally, down into the historic Alice Springs Telegraph Station finish line – wow!

What a journey! You deserve every bit of the accolades you will receive for your amazing effort in this Monster of an Ultra Marathon! The 231km Sonder Monster!


A totally unique and seriously challenging ultra race’. You don’t need to be a speedster but a high level of fitness and mental toughness will make a huge difference! There are literally thousands of photo opportunities! Some beautiful easy running interlaced with some extremely demanding, technical ascents and descents. Gaiters are not required to protect your legs, but some people opt to wear them. We do recommend as a minimum – good quality trail running shoes (and maybe a spare pair in your drop bags), hats, sunscreen, plenty of fluid intake and ongoing nutrition.  Some navigation is required to confirm you are on the correct path at all times – and remember – follow the BLUE arrows at all times!

We guarantee you will reflect on the significance of this run for many many years to come! Good luck!
