the North American continent has the Baja 1000, and other desert races.... and Australia, I just learned, has the Gascoyne Dash. Australia, the country that has everything deadly to humans except volcanoes.

The most remote desert race on the planet.  A 3 day race near Carnarvon featuring UTVs, motocycles, and car races, on a course that goes through an ancient checkpoint in Winnemia, crosses the Gascoyne River, returns to the Gascoyne Junction, and then heads back to the finish line through over 100km of uninterrupted river section.
