I am also on the coaching sales list I think.

Funny! Yes I stand corrected!
Your implementation of DFA is much faster by an order of magnitude.

I read on Twitter that ISM recommends doing shorter steps (3m) on a lactate test up to LT1 then longer (10m+) above it. Does anyone know if that is correct as I can’t seem to find any confirmation of it?
“Maximize work, minimize fatigue”. That’s it. It’s really all you need to know.

depends of the athlete level. if very fit individual he is doing shorter steps for their low intensity domain (up to ~2.5 - 3w /kg) but not all the way up to their lt1
i think its oversimplified but of couse i understand your approach
It’s more a case we overcomplicate things. It really is straightforward

Thanks. Not that tweet specifically but someone obviously referencing it. But they missed off measuring at 5mins AND 10 mins of the interval.

@sryke heard you mentioning training twice a day a few times on the forum. How would you approach this type of training within ISM style? Im planning a block with 4 days lt1 (2 hour sessions AM) and thinking about adding 60-90 min of easy endurance or recovery PM on those days.
@tshortt what you say? Overkill?
Not the first time I train twice a day, but never surpassed more then 2x a week. Trying to add volume in combination with work + family
Simply do it. As with any approach, monitor your fatigue, cut back if you get too tired. I don’t really see any particularities within the ISM approach. Simply ride endurance, modulate intensity according to how you feel.
Now it’s off-season for me, still keep on doing 2-a-days. Morning 1-2hours (mountain) running, afternoon 1-1.5h easy Netflix.

I’ve done something very similar this week 
I did a Joe Friel AeT test (1 hour @ 30 beats below LTHR) a few months back (I think a good surrogate for LT1) which came out as 260w. So, a bit below LT1, but volume was very high.

Not sure. I have never done 2 x day cycling training. Only running years ago. Looking forward to hearing how it goes. With this sort of low tempo training, fatigue can creep up on you unlike other approaches. When I’ve overdone intensity, it is much more obvious than overdoing tempo.
When I first started riding lots of tempo, I needed a “second set of eyes” (coach) because fatigue developed gradually.

I would not call this (low) tempo training (necessarily). And (for me at least) this is a self-regulating system. Day 1 - when fresh at LT1 … day 3 - well below LT1 (according to feel).

@sryke I take it that you also run. From your experience, does ISM Zone 2 translate well between the two disciplines, i.e. cycling and running?
Never did any La testing for running. From a RPE-Heart rate perspective I’d say yes but only in the mountains. My running biomechanics in the flats are too poor, main limiter. However, I do most of my running volume in the mountains.

I think this is highly individual.
For me it’s similar in RPE (which makes sense in my opinion) but HR is 12-15bpm higher in running.
However, I don’t believe that there is such thing as “high Z2 ISM-style training” in running. Around LT1 is very close to marathon tempo and this can be a very taxing workout you don’t really want to do too often.

Interesting perspective re marathon pace.
