From snow gum forests and alpine plains to wind swept ridgelines and historic high-country huts, the GSER 50 Mile offers a spectacular slice of Victoria’s iconic High Country. This is mountain running at its most raw and rewarding.

Our 50 miler event has been designed to allow runners who have conquered a 56k or 60km trail running event to take that next step, with the desire of conquering the mountains.  The course tackles trails that are predominantly single track and includes a section of the historical Australian Alps Walking Trail.
The grit and determination it takes participants to finish will be nothing short of extraordinary. The experience along the way – priceless.

Course Description:

Starting from The Moth, Whiskey Flat – Hotham Alpine Resort, runners will head out into the heart of the Alps, where every trail tells a story and every view stops you in your tracks.

The course winds through the breathtaking Dargo High Plains and across parts of the legendary Razorback Ridge, offering sweeping vistas, crisp alpine air, and unforgettable terrain. Along the way, runners will take on technical climbs, smooth flowing singletrack, and challenging descents, passing key landmarks like the Cobungra River and Federation Hut.

This is no ordinary 50-miler. With rugged trails, high-altitude challenges, and the beauty of the alpine wilderness all around, the GSER 50 Mile is built for runners who seek more than just distance – they seek adventure.

The journey ends where it began: Mt Hotham. But what happens in between will stay with you forever.
