If you're going to run a lot of miles they mostly need to be in your comfort zone because even if you don't hurt yourself with a lot of running out of your comfort zone most of us will have a hard time getting ourselves to run enough if it involves a substantial bit of misery..
Optimal training does exist. Optimal training is based on exercise science and the combined knowledge of athletes and coaches in our sport. If someone did 10 x 400m hard every day you would certainly tell them that they would have run better had they trained differently. That’s an extreme example but optimal training exists on a spectrum.
It seems you have a hard time understanding that “enjoyable” is a relative term and that if a specific pace is not enjoyable you are still capable of pushing yourself to do lots of running at that pace. Motivation is more complex than you give it credit for.
You also gloss over the statement I’ve made to you several times (here and in other threads) that a direct relationship does not always exist between perceived effort and the physiological adaptations you want to create due to the ways that each person’s brain interprets discomfort. That is a scientific fact.
I have nothing against enjoyment. I can run easy and enjoy it. I can run at a moderate pace and enjoy it. I can run hard and enjoy it.
Lydiard taught us that you achieve best results when you run near your maximum steady state. Most people would call that a moderate pace. Some people might enjoy that pace, some might prefer to go slower or faster, but preference is besides the point.
Maximum steady state is achieved around 2 mmol of blood lactate. It’s roughly 70-80% of your velocity at V02 Max. It’s not what this kid was doing before by doing his out and back runs at what he calls 100% but it’s not necessarily easy or comfortable running. For some runners hitting that intensity may require getting outside of their comfort zone and that’s okay.
Easy running or jogging is not going to give your aerobic system the stimulus it needs to develop to its maximum capacity. Keeping your heart rate very low is a good idea for beginners (and thus the title of the first chapter) but even Coach Renato Canova says that anything slower than 80% of marathon pace is a recovery run. Staying in your comfort zone is not Lydiard or Canova unless your comfort zone falls roughly within the 70-80% of vV02 window.
Lydiard found that you could build up to 100mpw or about 10 hours of running per week near this steady-state. You can run more than that but it should be easy running or jogging.
