Interesting discussion - I haven’t done the Amatola, but will probably have a go at it in the next year or so.
Anyone have the stats or a GPS track for the trail? I am mostly interested in the vertical profile.
I did the Giants Cup Trail in 15h52 on Saturday, not as fast as I was shooting for, but it is 62km with 2km in vertical - so not exactly a walk in the park (well, technically it is in a national park).
It would be interesting to put together a list of every 3+day hutted hiking trail in SA and compare the list in terms of vertical and horizontal distance. Altitude is also a relevant factor - I assume Giants Cup Trail would be the highest in terms of average elevation (roughly 2000m, with 2160m as a high point).
Non-hutted trails would be a contest between a Drakensberg Grand Traverse and Rim of Africa, I guess. And that would depend on definition, seeing as Golden Gate to Tiffindell has been done as a full Drakensberg Grand Traverse. For that matter - what is a “trail” - about half of the DGT is off-trail, and roughly half of what is on trail is a case of “follow that trail for 200m, then walk 50m and pick up the next trail that goes at a 30 degree angle to where you are actually trying to go”.
