Journey of a lifetime at any age, but to be in their sixties and do it is remarkable, and an inspiration to all. I can just about manage to get to town and back with handle bars full of shopping banging about on my knees, they carried all their stuff for the journey on their bikes by the look of it.
I've seen it from the air, along with the peak of Everest and to cap it all, Ayers Rock. Without moving an inch, no trudging involved. Summit of Snowdon in a tram and Sydney post office tower in a lift.
