I used to know a guy who was one of the earlier serious runners to get a Ph.D in Exercise Physiology. I remember him saying he'd found that there was some enzyme that was released in the muscles on runs beyond an hour that was damaging to them. He would never run longer than an hour outside of races. His version of the Sunday long run was three ten mile runs in under an hour each. So I'd be interested in Lismont's take on that.
I avoided the long runs without knowing about the enzyme. I did talk to Snell when he was at Dallas, as I had figured out how to run some intervals with a sore hamstring. He noted that would work, and gave me the physiology why, but I didn't have a medical degree so that part went in one ear and out the other.
On a somewhat related note, when Ian Thompson was running his 2:09 and winning the European and Commonwealth Games marathons I read a profile of his training. The thing that struck me most was that there was a 30 mile run listed as Sunday's session. That set me to a stretch of 27-30 mile runs for several weeks which I never liked and gave up as soon as I was convinced they weren't doing me any good. A few months ago on a Facebook group if old runners that I belong to someone who knew Thompson was writing about Thompson's training and said that those 30 Sunday miles were done as three ten mile runs.
