Whilst this thread is still well alive and kicking without JS even ruining it yet I have a question. So, I heard you mention Friel, this running would equate to his zone 4, of the 7 zones he has? Some in his zone 3? Which is all in zone 3 of the classic and Garmin type sense? And you are saying this is good for accumulation of tss or fitness score or whatever metric the software you use computes it as?
Ok, I'll try to answer this and bring it around back to TSS. TSS is just the trademark training peaks uses that Andy Coggan came up with. I've had run in with the man before on the time trialing forum. I do, however, think he stumbled onto this either by chance or genius. As I started out with this thread I said if I can get to about a CTL score of "60" ( this is irrelevant to everyone else, but meaningful to me) then I will be in 98% of where I wanted to get, no matter HOW I trained to get there. This applies to running and cycling. I don't have much to go on with other runners, but it was very relevant to others I knew as well, in cycling.
Right,so this would be in Friels zone 4. Or you are correct, zone 3 in a traditional sense.
Let's say I do a session, just above the threshold. This might be a super threshold session in Friels book (zone 5a). Let's say I do 40 mins work, in blocks of 4. With a small amount of rest. This is gonna be pretty hard and might give me a TSS for that 40 mins if maybe around 66. You have your warm up and down, you are looking at 90 for the session.
However, let's then decide we are going to run the session at 90-95% if this is a little under LT2, Friel's zone 4. I'm probably going to accumulate maybe 53 TSS for the same amount of time. Again, let's add a proper warm up and down the same as before and say we are maybe at 76-77 TSS for the session.
We've accumulated a little bit less, overall. So why do it? Well it's quite simple. The other session whilst generating more training load, is way more taxing on the recovery. I would probably need two easy days after that, whereas the second session in the example, I only need a day's recovery. So I can run three of those in a week for 228 worth of TSS, whereas the harder session realistically I'm capped at 2 a week. And let's be generous and say 180 worth of TSS (total session). Over time that adds up a lot, to more training load. Doing 3 slightly easier ones a week.
Then when you consider a lot of training programs get you to do a hard vo2 max session, vo2 max gives you a big TSS score, but you can't do much of it. Because it's actually really hard. So it's a high score per hour, but nobody does an hour of it. So it might leave you with even less of a training load as you probably can only handle that + a threshold session + some sort of straight tempo 30 min run if you are lucky, but you are still quite a bit under your TSS score with that combined, compared to the 3x sub threshold (Friels Z4). TSS in my experience going full circle feels like it's created reasonably equally, but the recovery is not weighted accordingly. So much as I said before like cycling, there seems to be this lovely sweetspot if you hit it right and disciplined, where you can create a huge bang for your buck, which is basically what the Norwegian model is in this hobby jogger version I outlined .
