Running on air

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, he 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 thousand dollars for a heart foundation.
