Based around the Nanga Bush Camp bunkhouse we head out onto the trails of Nanga around the Murray River. The are 3 legs which are run once for the 50 Miler and twice for the 100 Miler. The 50K is the first and 3rd leg. Accommodation is available on site.

Runners climb the Darling Scarp up Goldmine Hill on a quiet gravel road before following the Munda Biddi mountain bike trail to the small country town of Dwellingup. There is ~925m climb and 775m descent in the marathon (47.5K) and ~340m climb and 360m descent in the Half (23.4K).
