Lydiard or Speed Endurance?

[Stolly]

What I am at odds with is this idea that there aren't a lot of people with joint disorders who have got these problems by overdoing the exercise.

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
