For a lot of people running should be fine for their knees if done properly.
As far as I can tell, running is most likely to damage your knees if you’re (a) very big/heavy (b) have poor running technique (most people don’t learn to run properly/efficiently) (c) run a lot on bad surfaces (avoid running extensively on surfaces that are banked, or where you may step in potholes!) (d) have a genetic predisposition to knee problems or have brought on ostearthritis-type conditions through poor diet (happens sometimes with exercise anorexics).
As a past competitive runner, I’ve spent a lot of time with running “lifers” (>10,000 miles on the legs) and knee problems don’t seem to be particularly common (though obviously there are some selection effects there). Anecdotally, I have no knee problems after 6 years of 100mile/week training and most of my sports friends who do have them as a result of acute injuries (usually soccer).
That said, there’s enough weak evidence to suggest that this kind of heavy aerobic training may not be good for long-term health and longevity to cause me to reduce my running to 20-30 mins/day (supplemented by weight training).
I actually did not want to go too deep into discussing specific sports and wait for another 24 hours, but...
I never had actual problems with the knees myself—I’m neather heavy, nor run that much at all (100mile/week for 6 years is extremely impressive!), also I eat helthy and think my technique to be okay. But I am very young. My grandfather, who has been doing a lot of sports his whole life (to my knowledge he still rides his bicycle for 50 miles a day or something at age 80) had some knee problems and therefore changed from relatively serious marathon running (best time ~2:40) to swimming and bicycling. Of course these are just anecdotes that do not prove anything. I would be very interested in the current state of research on the matter.
For me the most important argument against long-distance running is that it seems to conflict with general fitness. After running my second marathon I pretty much sucked at everything else, even riding a bicycle...
Also, long-distance running takes a lot of time to practice, so now I changed to less than daily interval training, also supplemented by weight training.
Some emerging concerns I’m aware of for really serious runners: heart problems due to thickened heart wall, skin cancer (just due to being out in the sun so much, sweating off sunscreen).
Potential causes for concern: lots of cortisol production from hard aerobic exercise, inflammation.
I keep wondering whether sports where the major point is overriding the desire to stop are actually a bad idea—that desire to stop might have evolved to be protective.
Does running destroy everyone’s knees? My impression is that it’s risky for knees, but not everyone takes damage.
I remember the existence of an article in Runner’s World long ago where they interviewed runners who hadn’t taken damage.
The comments to Running with the Whole Body have some people who say the Feldenkrais work in the book protected their knees.
