Fascinating guy—I love his hat, though I think it would drive me absolutely bonkers to have something bouncing around my peripheral vision.
I do think he discounts luck as a key motivating factor in his success. Anyone who runs that sort of mileage and races most weekends and doesn’t get injured is just plain lucky (or @shiggyrunner). Even if his lack of strength work and post-run stretching/rolling was somehow positive instead of negative, all it takes is one bad fall to damage tissue or bone such that you’ll be dealing with it for the rest of your life.
I was also struck by how much they kept asking him about age. Lots of us have set PRs—usually at longer distances—in our 40s, mostly due to smarter training, extra strength work to prevent muscle loss, and so on. That’s less common in our 50s, but it’s not unthinkable. And there’s certainly no reason to stop running and competing, even if the goals change somewhat.
