Bindarri National Park is the draw: rainforest trails tucked into the Coffs Harbour hinterland, with the Rumble in the Jungle Trail Run built around waterfalls, lookouts and that damp, green feeling you only get when the bush closes in. It has the feel of a proper trail runners' race rather than a polished road event, with the terrain doing most of the talking and the setting giving you plenty to look at when your legs start arguing.
Expect a course that leans into the park's natural features: singletrack-style running through rainforest, climbs toward lookouts, and sections where the reward is one of those waterfall, lookout, and rainforest moments from the listing. The crowd is likely to be people who came for trails first, with Coffs Trail Runners behind it and the finish line carrying that muddy-shoes, post-run chatter energy.
