Rob Ginnivan ran 13 miles on a treadmill, powered by a small generator as he braved the cold and the altitude above the Australian capital.

Although he is an experienced runner, it took him twice as long as normal to run the distance because he could only take small steps on the treadmill.

“What I didn’t count on was that the basket actually tilted, so it was like running up a hill,” Ginnivan said.

“Every time I took a step the basket would sway from left to right so I kind of had this sea type motion being in the air. It was quite bizarre and made it very difficult,” he added.
