Been doing NSM for 2 weeks now so I have done two of each session so far which are:

9x3 mins 15k pace
4x6 mins @ 20k pace
3x10 mins @ 30k pace

Even though the 4x6 mins is actually the lowest volume of SubT within my sessions, it for some reason feels the hardest. Not sure if it’s just a mental thing, my average heartrate in the reps between the sessions are very similar.

Do other people experience a similar thing? If so, is it quite individual or are some SubT intervals inherently more difficult?

So I’m only 1 week into NSA, and today done my 4x6mins @ HM pace. My intervals.icu chart has just about dipped into the green.

I have read the book and I believe James says you should be in the grey. So what does this mean that I have gone into the green and does it mean I need to back off? If so, do I just do less sub T per week? Reduce my sub T rep paces? Run less mileage?

As a note, my chart for before I started doing this approach and was training for my first marathon was constantly green, and 1-2 days before my deload weeks it would dip into red.

Any suggestions about what to do about my training load?
