I was looking through my old videos from a few years ago, and came across one that really inspired me. Amongst all the amazing people who ran the Ice Marathon 2007, there was one person especially inspiring. Susan Holliday, from UK, became the first woman ever to run a 100K in Antarctica. 

What kind of perseverance is that to run in the snow and ice for 21 hours and 50 minutes! I also did a personal interview with her (video below) to learn about her motivation and inspiration.
