An iconic athlete, author, Emmy-award winning broadcaster and advocate for sports and social causes, Kathrine Switzer was the first woman to officially register for and run the Boston Marathon in 1967.

My conversation with Kathrine went beyond running, and we talked about the importance of staying active as we age. She also provided some tips for masters runners who want to get the most out of their training, and we talked about her non-profit, 261 Fearless.
