Endu1 - Proud Official Hydration Partner of the Great Southern Endurance Run (GSER)

We’re thrilled to announce that Endu1 is the official hydration partner for the Great Southern Endurance Run (GSER) - one of the most rugged and picturesque mountain trail runs in Australia.

As one of our partnered races, GSER combines world-class trails with Endu1’s premium endurance sports nutrition and hydration support. It’s an all-inclusive event with the big-event feel, while still maintaining a strong community vibe.

Starting and finishing atop the Victorian High Country, GSER runners will venture deep into the mountains, summiting peaks with stunning, long-lasting views, and traversing sections of the iconic Australian Alps Walking Track—all within the Victorian Alpine National Park and Hotham Resort boundaries.

GSER 2024 Events (November 16-17):

• The GSER 14km has been crafted as an ideal introduction to mountain running, taking runners along the scenic Hotham Huts loop trail with breathtaking views as a reward for your efforts.

  While it will require true grit and determination to complete, the adventure is well worth it. The stunning vistas and the cheers from your trail crew awaiting you at the finish line will make it all the more rewarding!

• The GSER 28km is a significant step up, taking you into the heart of mountain running. The course features challenging trails, steep climbs, and rewarding views that make the effort worthwhile.

  It will take true grit and determination to conquer, but with your trail crew waiting to cheer you on at the finish line, you'll make it happen!

• The GSER 56km offers runners an unforgettable day on the trails, featuring some of the most iconic high country routes. The course takes you along the Bon Accord Track, Bungalow Spur, Mt Feathertop, the Razorback, Mt Hotham, and the Mt Hotham Huts Walk Trail, all before finishing at the Alpine Gateway.

  If you've conquered a coastal 56km, your next challenge awaits in the high country. We know which one is more rewarding, and we’re confident you’ll love what we have in store for you!

• The 50 Miler / 50 Mile Replay event is designed for runners who have mastered a 56km or 60km trail and are ready to take the next step—conquering the mountains.

  The course primarily follows single-track trails, including significant sections of the historic Australian Alps Walking Track. The grit and determination required to finish will be nothing short of extraordinary, and the experience along the way will be priceless.

For women participating in any event, join the #WomenOfGSER group, led by Race Director Megan, to connect with a supportive, empowering community of women on the trails.

At Endu1, we’re beyond excited to hydrate and fuel all GSER runners as they take on the challenge of a lifetime. With Endu1 by your side, you can focus on the adventure while we keep you fuelled (and boosted)!

We can’t wait to see you and your trail crew in the mountains this November!
