The 35km is a stern test with a significant climb in this first section with the highest point in the race at over 700m before the 5km mark. Collins has simple advice for runners taking on the 35km run.
"It doesn't seem it at first as the scenery is so nice and the gradient pretty rolling, but 3km from the finish you hit a big hill and lots of people haven't saved up some energy for this last climb," said the 37-year-old.
The Lactic Turkey team has a goodie station - supplying lollies and drink - at the bottom of the climb.
"But have a good look around as you run. People often get trapped into the tunnel vision around the track they are running, especially the more tired you get, but this event offers some stunning views."
Collins is not surprised off-road running is growing in popularity. "People have suddenly realised that running doesn't have to be the grind that it can be by just road running. You can have an awesome adventure with every run, as you don't know what's around the corner.
"And as people tell their workmates about what they got up to in the weekend, it isn't just ... 'I went for a two-hour run around the waterfront', but more ... 'I ran for a couple of hours in the bush and found this amazing waterfall and these wild pigs ran across the track in front of us'. It spreads the word how fun it is."
