Billy Mills, who is best known for being the Oglala Lakota athlete who won the 1964 10,000-meter run in Tokyo, will be sharing his inspirational story at the United Tribes International Powwow

Mills, now 76, lives near Sacramento, CA where he makes numerous public appearances to share his experiences.

Not only is his gold medal win considered one of the greatest moments in Olympic sports history, he inspired the 1983 movie 'Running Brave.' Mills was also presented with a Presidential Citizens Medal in 2012 by President Obama for his work with 'Running Strong for American Indian Youth.' This organization addresses both the physical and emotional needs of the American Indian people. Their goal is to create a sense of hope for those who want to improve their communities and the lives of their families.
