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.
