Welcome to the Great Southern Endurance Run 2021

GSER is back for 2021 with a couple of changes taking place; revised courses on 2019’s with a few added extras and a couple less km’s, along with the addition of our 28km event (A perfect introduction to Skyrunning) and the event now being under new ownership from the team at Ultra Endurance.

With COVID restrictions causing many events within the last year, that would be used as qualifiers for GSER being either canceled or postponed, we also have a slightly different way of assessing your qualifying. More details for qualifying can be found here.

We are very excited to see you and your trail crew in Harrietville, November 12th to 14th 2021.

Regards Matt and Megan (the Ultra Endurance Team)
