This is one shot from a trip covering the Simpson Dessert Cycle Challenge a race for cyclists across the Simpson Dessert.
The Simpson is amazingly beautiful, this shot was taken early in the morning as the first set of vehicles are ready to leave. These are the people who set the couse for the morning.
The Simpson is a sand dessert, with huge dune systems that create large parallel dunes that run for 100s of kilometers. Crossing this dessert is an endless sequence of dune crossings.
