This will be a replicated ride of the ride I did in 2014 with a Swiss couple riding hardtail MTBs with 2 panniers (I have a photo album of that ride). While the ride is unsupported, I have friends along the way and local knowledge (I have lived and worked in the Flinders Ranges). You can also ride the Mawson Trail (supported) with https://www.bikesa.asn.au/outbackodyssey in 2021. I will be recommending some short-cuts... the northern part is the BEST so two short cuts are pretty much locked in. In 2011 we took 3 short cuts and 80kms in a car. I hope to keep it to only two short cuts but the weather can change plans. Here is my blog http://mawsontrail.blogspot.com/
Oh... Nearly forgot to mention... the tour involves watching the Melbourne Cup (a horse race that stops the nation) in the Blinman Hotel. This time I plan to buy a ticket to the swanky lunch (instead of eating leftovers as we just happened to stumble in on that day).
