In November, 2017 a group of adventurous rail runners set out to complete the inaugural Great Southern Endurance Run 100.

The GSER 100 - as it is known - is the hardest 100 mile trail race in the Southern Hemisphere and the 5th hardest in the world based on elevation gains.

In 2017, it took the runners from Mt Buller in the Victorian Alps to the town of Bright, a journey of 182km with over 10,00m of elevation gain and 11,000m of descending.

The grit and determination it took participants to finish was nothing short of extraordinary and the experience along the way; priceless.

We wanted to find out why someone would sign up for this race and how they did it. 

How did they train for such an incredible race, what they would do differently if they were to do it again and what advice they have for you if this event has caught your attention?

Here are the stories of 3 different women who completed this epic adventure.
