To sirpoc, shirtboy, or any of the others who've adopted this system and have a solid understanding of it: I'm wondering if since the system is based on time for the longer efforts (3-minute and 6-minute intervals), would it make sense to shoot for 1-1.5-minute intervals in place of the 400m intervals? I ask because it seems like the amount of time spent at the appropriate pace puts all runners in a similar lactate state, whereas if a slower runner has to spend 90 seconds covering 400m, for example, doing 20 reps is going to tax them a bit more than Jakob, or one of the guys running a 17:00 5k.
It seems to me that if you're running at the appropriate pace for a given interval, running for longer just to reach a specific distance means more time than others spent at a given level of threshold, and thus a higher lactate mmol value. The faster you are, the less time you'll spend at any given pace, and I've just been thinking that since time is the factor with the longer distances, maybe that should be the goal for all paces.
I do understand that many have come to view 6-minute intervals as circa 2000m, and 3-minute intervals as circa 1000m, but looking into the Norwegian training, they seem to emphasize time over distance, except for the shorter 400m intervals and hills. Alternatively, of course, a slower runner could stick with the 1000m or 2000m distances, and just do fewer reps. I'm wondering what all of your thoughts are on this.
I think this might be in the thread somewhere? Or maybe hard2finds chart or spreadsheet some dude made in Strava group. But if you are running more than say 1:40 for the 400s, just limit it to time and whatever distance you cover. I believe sirpoc said along lines of 400m or like 1:30-40 or whatever comes first. And so on 1ks or 3:30-4 mins whatever comes first. Up to 3x3k or 12 mins whatever comes first. It might be on Strava he said this. There is a good group Fusio from this thread made. Almost 100 members.
One note: I follow sirpoc on Strava now for a while, I have never seen him do 400s anymore. I think he said lactate is the same, but body feels more taxed in terms of muscles.
