A little late in replying, but yes, I've done 3 of them. The latest was a few weeks ago. Over the last couple of years the format has changed from moving from camp to camp each night to having a fixed base and doing day rides. On most days there is an easy and a harder option. Sometimes the distances aren't great, but the terrain sure makes up for it!
There were only around 40 riders in this year's event, which was disappointing (There were 180 in the first event I took part in, and around 90 last year). There were a few people from Melbourne & Central Vic on the ride this year.
I hope it continues.
