That’s interesting. I had small niggles pop up when I’d go faster but I got incredibly fit incredibly quickly, and it definitely made my workouts better as well. I noticed that I had to sleep 9+ hours or I wouldn’t recover though.
9-10 hours of sleep is pretty standard for hard training. If you can’t sleep, you can’t train hard.
And there is that fine line between good stress and overtraining. Imagine you are doing 2 hard workouts and 10 easy runs. You might get better replacing 4 of the easy runs with steady efforts. But if you do 6, you hurt something. You need to figure out where the line is.
the poster child for these hard steady runs were guys like Ron Clarke and Mark Nenow who rarely did intervals but do lots of fast runs of around an hour. It worked for them. Or El Gs rumored training of 45 mi runs at 3:00 pace. Some people just have crazy recovery capacities for these hard but sub maximal efforts.
If you want to get technical these hard steady runs are close to the 2.0mm double threshold sessions. Science doesn’t like them but plenty of coaches/training plans have had them as a base.
