2024 Events

Capturing the best trails within the Victorian High Country.

GSER 14km has been designed as an introduction to mountain running with the course tackling the Hotham Huts loop trail that provides very rewarding views.

There is no doubt that this will take true grit and determination to finish, but the views alone is worth the adventure plus the cheers from your trail crew will be awaiting your arrival at the finish line!

GSER 28km is a step up to pure mountain running with the course tackling some very sweet trails and including steep climbs with very rewarding views.

There is no doubt that this will take true grit and determination to finish, but with your trail crew waiting at the finish line, you’ll make it happen! 

GSER 56 km provides all runners an epic day out on the trails. Our course showcases the iconic high country trails of Bon Accord track, Bungalow Spur, Mt Feathertop, the Razorback, Mt Hotham and the Mt Hotham Huts walk trail, before finishng at the Alpine Gateway.

If you’ve completed a coastal 56 km, your next challenge is a High country 56 km – we know which one is more rewarding and think you’ll love what we have in store for you!

The 50miler 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 include the historical Australian Alps Walking Trail for many parts. The grit and determination it takes participants to finish will be nothing short of extraordinary. The experience along the way – is priceless.
