Chances are if you’re driving across the Nullarbor, linking Western Australia and South Australia, you will see cyclists making the arduous trek on two wheels.
Out in the elements on one of the most isolated highways in the world, most of the cyclists are young and fit, making the journey for charities or the record books.
For New Zealanders Del and Cindy Henley, the trek is about taking time out from their retirement village south of Auckland.
Both are a spritely 81 years old.
The pair are on their second Nullarbor pilgrimage, but it’s not their longest Australian bike ride.
“We took up cycling when we were 70,” Mr Henley said.
