In this episode, Michael Doyle speaks with Nick Thompson — CEO of The Atlantic and author of the new book The Running Ground: A Father, A Son, and the Simplest of Sports — about how he became faster in his 40s and why that journey uncovered a deeper story about grief, trauma, psychology, and the complexities of the father–son bond. Nick explains the book’s origins (02:04), how cancer shaped his mindset (04:09), and why writing candidly about his father was both terrifying and necessary (06:06). He recounts his father’s extraordinary life (07:15), how running kept them connected (11:59), and why midlife can break or remake us (47:12). The conversation digs into training nerdery, including mileage and threshold work (23:05), diet and supplements (26:54), gear choices and heart-rate breakthroughs (28:59), and the central governor theory (31:10). Nick also shares insights on AI and future training tech (32:45), the powerful story of Michael Westphal (38:35), how he knew the book was finished (45:05), and what running means to him now as he chases new goals (53:21).
