As I'm beginning my 'base period', I'm beginning to do 2 days of TH intervals (2x15-25:00), twice a week (Tues and Thurs), and a mid-tempo ride on the weekend.
However, as I do the mid-tempo ride solo, I've decided to incorporate a small amt of AWC intervals (4-8 minutes total work, once a week), into one of my weekday rides (if I did a group ride, I'd just count a couple of hard, unstructured efforts and call it good). As I have pretty low AWC, I figure I should some some hard efforts so I don't totally de-train this energy system.
My question is this: last year I did this same thing, doing 2-4 2 minute efforts at roughly 150% of FTP, resting 15 minutes, then doing my TH intervals. The quality of the ensuing TH intervals seemed to suffer, going back and looking at last year's power data. I did this workout on Tuesday, then Thursday just did 2x20:00--the power on Thursday's intervals was roughly 5% higher--and in quite a few instances (about 30% of the time), I ended up skipping or cutting short Tuesday's intervals. Since my primary focus is building my TH power, would it make more sense to do the shorter, harder intervals AFTER my TH intervals, even though this goes against the often-touted principle of 'shorter intervals first'??
Thanks for any useful input!
