American Yolanda holder became the worlds best walker after travelling 3100 miles in the Self-Transcendence 3100 Mile Race. She was so happy on the last day you can see and feel it in her interview with Utpal Marshall.

During her race she hoped to inspire and motivate her friends and followers with a 52 day challenge. Encouraging them to work out each day she competed. What a champion!
