Lydiard or Speed Endurance?

[CL]

I don't agree with this at all CL. I'm running nowadays like never before (approx 200 miles a month all off road) and having just hit the grand old age of 56 and, having played football and then done a completely bonkers form of 'hong kong fuey' for years while younger, I have no joint disorders at all (that I know of). If anything my joints feel better than ever. All of my injuries from running have come from twisting ankles and knees over rough ground and descending like a mental case, which I tend to try and refrain from nowadays.

I read something on the internet a couple of years ago (so it must be true ) about running not giving joint problems in fact. I can't now find the article in question but I did find this one.

I do agree with you on the need to put effort in and that the only way to run faster is to (duh!) run faster. I do think that quite a few slower runners forget this solution though because its too painful

You're missing the point entirely. You are telling us there are no health consequences in overdoing the running over what could be a short or long period. I know there are and I only need one example to demonstrate the principle. I've given it. Now you might be lucky and get away with it or you might not but at least it should be considered when deciding how much training to do.
