...performed in training, but highly motivated. Is this Z4 work? Or Z5? (Coggan zones, here.)
I feel like it would be Z5, since it seems to be at a higher intensity than a 1hr time trial. Then again, it's a longer duration than is "routinely achievable" for Z5 work, and I can pretty reproducibly do this effort within a few percent almost on demand.
From a HR perspective, it's looking like Z5 to me. While I have no power measuring tools yet, I do it uphill, where power estimates are possible. According to that wacky German website whose URL I can never remember, the 20min effort is around 280 W, while a 1hr uphill effort (race conditions) was around 250W.
So, Z5, right? I guess what's surprising to me is how much less intense this feels than the efforts in, say a 5x5min workout. Sure, the last 5 minutes are total agony, but the preceeding 15 aren't as misery-inducing. Also, the perceived training stress isn't as great for the 20 minute tt; the next day I tend not to feel as fatigued. If it works for me, and is less stressful than the 5x5s (which I usually do on the trainer), might this be a decent way for me to get in Z5 work? Or, am I working in a "no man's land" between 2x20 and Z5?
