UTMB Qualifier 2021 5 ITRA Points

Ellery Creek Climb

Ellery Creek Climb

Is the 231km a bit more than you wanted to chew off? Come and run the 128km Ellery Monster trail ultra-marathon through some of the most spectacular and runnable sections of the Larapinta Trail. Starting at 9am on Saturday from the beautiful Ellery Creek Big Hole Waterhole. The route starts off with a fantastic flowing and gently undulating run across the Alice Valley on Section 6 of the Larapinta Trail.

Now that you have warmed up, enjoy the hospitality of the Hugh Gorge Aid station as you refuel for an epic afternoon traversing Hugh Gorge and then ascending the most spectacular Razorback ridge into the night. Catch the Aid Station crew at Junction 4/5 (Birthday Waterhole) for a refresh. From here, you will climb the amazing Brinkley Bluff. A summit that will allow you to view, by moonlight, a magnificent ancient landscape in every direction. A 10km technical descent will move you through to the amazing Standley Chasm aid station. Again, refuelling here is a must as you are about to undertake another hard slog for the next leg. Traversing the rugged back canyon from Standley Chasm, up along the high route, most of this will be in the dark or early morning as the trail markers reflect your way forward for some distance.

That is enough of the hard slog for a while…you run through some more amazing winding relatively gentle single track to Fish Hole waterhole, Mulga Camp and into Simpsons Gap Aid Stations where you only have 2 notable climbs and about 25km to go. Climbing up  Euro Ridge is one of the most rewarding views and your first glimpse of the destination, 13kms from the finish line and provides the final ‘sting in the tail’ before descending down to the finish line at the Telegraph Station.

A 128km Ultra Trail Marathon – what more could you want. Running on challenging, rocky, technical terrain interlaced with sensational sections of flowing undulating hard-packed single track.

128km Ellery Monster

128km Ellery Monster

A morning road trip of approximately 100km out of Alice Springs to the Start line at the beautiful Ellery Creek Waterhole. This is ‘the locals’ swimming hole, where most Alice Springs residents will come at least once each summer to hang out for the day!

Starting ‘on the beach’ – who would have thought…! You will join the Larapinta Trail in a hundred meters or so for the journey across Section 6 to the breath-taking  Hugh Gorge. Approximately 30km of flowing single track joins the Heavitree and Chewings Mountain ranges together which provide endless vistas as you traverse the Alice Valley.

At the Hugh Gorge Aid Station, refuelling is a must! From here you will scramble up the Hugh Gorge for 4km or so. This is kind of a river rubble hopping experience with big steep cliffs either side until the exit from the riverbed where you turn right below unbelievably large glowing red cliffs to continue up Linear Valley to Fringe Lily Creek.  You commence your Razorback Ridge experience by ascending a switchback climb of incredibly well hand made single track! The ascent is technical, the ridge is technical and the descent into Standley Chasm – you guessed it – technical! But the rewards are phenomenal!

Beyond the Standley Chasm start line 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 endurance, and is the first of only three significant climbs between you and the finish line. It is the most spectacular and technical of all the climbs. Don’t forget to take some priceless selfies on top of this ridge.

Off this ridge, down through fish hole waterhole aid station and continuing on 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. You may well encounter runners coming through, or indeed, you may pass runners from both the 231km and 65km events between here and the finish line. 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!
