I mentioned a couple of weeks ago that I thought the recommendation to walk through water stations during a marathon was the best (running) advice I heard during the pandemic. The advice is included in this link under the section 'Walking Breaks'. It's allegedly a fairly well-known bit of wisdom, but I don't recall hearing it in my ten years of running (and I don't know any healthy runner who walks with the regularity described in the link).
This made me wonder about rest in general and how little we understand it. Most of life is spent acquiring and developing new skills - resting is a notable exception; most of us were better sleepers at one-day old than we are now. Do you know the right balance of effort and rest in all your activities? It seems like the most important knowledge; naturally, most of us have no idea.
