Hi Paul, thanks again for letting me continue, and for the kind words in the race report.
The true hero of the day certainly was at the back of the field - Julie Savage. The most patient and encouraging sweep ever. I doubt I would have made it to the end without her there.
Thoroughly enjoyed the event, and look forward to doing another of your events.
Razorback—March 2019

22—40—64—85 km Alpine Runs

This classic Alpine run offers four challenging distances in some of the most spectacular country in Victoria’s Alpine National Park. In 2023 Hells Cauldron—The Anvil 85 km variant of the Razorback Run is open to all runners.

For years Running Wild has been developing and testing a more challenging run to complement the Razorback Run, but one that goes back to the basics of trail running using a map, compass and trail reading skills, so now we present an "extremish" ultra run open to experienced trail runners.

The Run

Hells Cauldron—The Anvil, where you can be roasted by the sun, lashed by howling winds and frozen to the core by the icy rain and snow—all in one day; a run where you must be prepared for everything. For those entering The Anvil, it's not when you will finish, but IF you will finish and how wrecked you will be.

The Hells Cauldron—The Anvil ultra is one of Australia's toughest and most spectacular mid distance Alpine ultra trail runs, with over 4,800 m of ascent and descent over 85 km. If you are contemplating this run, be aware, it is extreme in difficulty and has cut off times that will challenge you to the hilt.

For those still wanting a challenge, there is the 64 km Razorback Ridge run, which takes in the entire length of the Razorback as well as heading across to the Bogong High Plains to take some great ascents and descents as well as some of the most stunning ridge running in the Australian Alps.

The 40 km Razorback Circuit gives you a great climb to the summit of Mt Feathertop, the second highest peak in Victoria, a terrific ridge run and a quad busting descent.

The 22 km short course Razorback Ridge offers  a delightful day out to the Summit of Mt Feathertop and back along the Razorback.

2023 includes the 58 km loop for the benefit of runners in the 160 km Alpine Challenge as it gives them the chance to run this section in daylight, whilst 

Set in the heart of Victoria’s high country, the Razorback Run/Hells Cauldron is one of the most amazing high altitude runs that Australia has to offer.
