Almost anyone can be healthy at 20 and build enough fitness to run a Triathlon if they're willing to work hard enough. But what about at 81? What sort of diet and lifestyle regimen does it take the preserve enough of your body's functionality and mental capacity so that you can still suit up for the starting line in your eighth decade of life? In today's podcast I talk to Dr. Ruth Heidrich, who's run more than 60 marathons and triathlons and taken home more than 1,000 medals, held three world fitness records for her age group, was once voted among the top 10 fittest women in North America, and accomplished most of this after beating cancer of the breast, bone, and lung. In the interview we talk about the singular dietary strategy she used to beat cancer and fuel her athletic pursuits, as well as: How she's aging physically and mentally in comparison her peers. Beating cancer, arthritis, and building her bones. What keeps her enthused about life at 81. The heavy opposition and derision she faced when she upgraded her diet in the 1980s. What she eats on a daily basis. What daily training looks like for an 81-year-old triathlete.
