Had a great day out on this stunning trail. Can't wait to do it again.
Had 2 x phone conversations with Rangers at Flinders Chase and attended the pre-hike briefing where a ranger sits with you to go over the trail (even though just spent 5 days hiking the trail with my family).
Running the trail is not unheard of but not common either.
Just reassure them that you are prepared and are carrying sensible gear and equipment (ie) PLB, head torch, thermals, water carrying capacity.
Rangers were fantastic - supportive and interested.
Made use of available water at each campsite except for the last campsite as I still had enough to finish and carried everything else. Still calling it supported, because my family met me twice on the trail and I had a cheeky coke out of the car.
Stopping at campgrounds will add distance to your run - the last campground is 500m from the main trail.
I highly recommend this run.
