Grampians Peaks Trail 100 Miler

Grampians Peaks Trail 100 Miler

The Grampians Peaks Trail 100 Miler is one of several events held along the Grampians Peaks Trail in Gariwerd, the Grampians National Park. The full trail measures 162 km with about 7,700 m of total elevation, running from Mt Zero in the north to Dunkeld in the south. Much of the route goes through rugged and varied terrain and remote wilderness areas. The trail is divided into four main chunks, each with major aid stations, and much of the marked trail is rocky.

The event basecamp and headquarters are in the central township of Halls Gap in Victoria, about 260 km northwest of Melbourne. The GPT100 Miler is presented by ASICS, has Visit Victoria as a major partner, and is delivered by SingleTrack Events. The race is part of the World Trail Majors series.
