WHAT IS THE MOUNTAIN SERIES?

The Trailsplus Mountain Series is a collection of five iconic trail running events in Victoria designed for runners from beginner all the way to ultramarathon distances.

Each race stands on its own, but together they form a season-long journey through some of the region’s most varied and rewarding terrain. From flowing forest trails to steep climbs and technical sections, every location offers something different: a new test, a new landscape, and a new experience.  

Take part in a single trail race or complete the full series across Victoria’s premier trail running destinations.

WHY ENTER THE SERIES?
