(CANBERRA, Australia) -- Most people would feel plenty accomplished if they could finish a half-marathon, and even more so if they trekked the 13 miles for charity. But that's child's play for Aussie Rob Ginnivan.
On Thursday, Ginnivan finished a half marathon while on board a treadmill -- which had been loaded onto a hot air balloon.
Ginnivan told the U.K. Telegraph it took him longer than he thought. "What I didn't count on was that the basket actually tilted, so it was like running up a hill. 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."
Ginnivan is hoping the stunt will help him raise around $70,000 for a heart foundation.
