I agree about the misrepresentation of endurance as the "holy grail". However, I think that the principal harms of endurance training are chiefly in highly competitive, obsessive racers who in a high-volume, high-intensity mode without ever taking significant rest.
There are a few people in the ultrarunning world who have been very consistent in finishing very difficult events on a comparatively low-volume, high-intensity training program. They are still doing long stuff, but instead of doing several long runs a week, they do a very long, very slow effort once every few weeks. They aren't winning any races, but they have a lot of longevity in the sport.
James--I was at the back of the pack in the 50. I probably walked more than half of it. I twisted an ankle around mile 35 and walked almost all of the last 12 miles or so.
