Why I’m Doing The Great World Race (7 Marathons on 7 Continents in 7 Days) with my Daughter

In today’s conversation Dr. Greg explores the decision he and his sixteen-year-old daughter Ingrid made to attempt seven marathons on seven continents in seven days. He shares how persistent injuries led them to stop, recover, and rebuild their health from the ground up before they were ready to begin endurance training again. The episode traces the project from a series of small rehabilitation sessions to a potential Guinness World Record attempt, while introducing the Great World Race as a living exploration of human physiology, adaptation, and possibility. The event is scheduled for November 15–21, 2026, beginning at Wolf’s Fang in Antarctica and finishing in Miami.
