Dozens of elite ultra marathoners are taking part in the Badwater Ultramarathon today but only one of them, Lisa Smith-Batchen, ran 160 miles from Las Vegas to the start! It's part of an effort by the former Badwater champion to raise 500-thousand dollars for AIDS orphans. Lisa's crew (as if they didn't have enough to do) called in and left messages of Endurance Planet's voice mail detailing the run from Vegas to Badwater. Listen in today as we hear about high-temperatures, blisters, bats, and one determined woman. (You can learn more about Lisa's journey and her cause on http://www.lisasmithbatchen.blogspot.com/.)
