My partner and I will be on the trail mid August.
So I can't provide any real information yet.
But I have researched this over the last 3months until my eyes bleed, so I'm feeling well prepared (we will see).
It seems that the trail is pretty user-friendly with lot of water tanks, maps, markers and exit points. Plus it looks relatively flat (typical ascents are no more than 300m, apart from Mt Sonder).
But then again, all those sharp, dry, loose rocks should provide a bit of a challenge.
I'm struggling to trust the walking times in the parks-NT-maps/Chapman-book. They just seem soo... tame.
Section 1 is 24km with undulation: recommended time is 9h of walking over 2 days? (assuming 15-20kg pack and average fitness level)
I'm not sure if the track really is harder than I am expecting or if 'average fitness' is little too subjective.
Oh well, one way or another, this is something we will find out in August

We plan to do this over 14days + 1 day chilling out at glen hellen.
There is great thread by user 'forest', which shows him doing it in 10days.
http://bushwalk.com/forum/viewtopic.php?t=14504I think the 'standard' length is somewhere between 16 and 19days
How long do you plan on giving yourself to walk it?
BTW, we are going East to West. For you and/or anyone else lurking: I'm happy to share transport from Mt-Sonder/redbank back to AS on roughly the 21st of August. Just throwing that out there.
