Indigenous runner Adrian Dodson-Shaw is turning up the heat.

The first Indigenous Australian to run the North Pole marathon two years ago, is set to tackle one of the most extreme marathons on Earth, the annual volcano run in Chile, this week.

Dodson-Shaw, whose hometown of Broome is just 19m above sea level, will line up with other competitors at Atacama, in the heart of the driest and highest desert in the world at an altitude of 4475m and surrounded by about 10 volcanoes.

He will then run 42.2km on dirt roads and by gorges to a finish line 3603m above sea level.

The field is restricted to just 40 competitors.

Dodson-Shaw, head coach at Robert De Castella’s Indigenous Marathon Project, said coping with the thin air at high altitude would be a challenge.

De Castella wished him luck.

“Running a marathon is hard, and doing it at 4000m above sea level when even walking makes you huff and puff is just crazy hard, but that is exactly what Adrian Dodson-Shaw is about to do,” De Castella said.

“This will be Adrian’s third marathon, and when the other two include the biggest, the New York City Marathon, and the coldest, the North Pole Marathon, I guess it’s natural to make your third the highest.”
