While I really think highly of this training approach and appreciate all of the discourse on here as well as the NSA strava group, one thing that I wanted to bring up is that *for me* the paces suggested on the excel spreadsheet seem to be overkill when compared to the lactate readings I get when hitting these paces. I have a lactate meter and in order for me to keep my lactate <4 (I personally aim for somewhere between 3.0-3.5) I have to run slower by a significant amount (15-20 seconds/mile) to stay under threshold. It could be because I am not as aerobically as fit as sirpoc and others, I'm not quite sure. Before you ask, I plugged in a 5k time trial result done untapered in non-carbon fiber shoes to generate my suggested 4min, 8min, 12min workout pace. What I've found is that if the intervals even feel slightly hard then my lactate reading at the end is usually >4. Additionally, I would recommend against trying to correlate HR with lactate levels (obviously if your HR is 200 your lactate is going to be high and vice versa) but I've done workouts where my HR has stayed relatively low and my lactate reading was 6.X
Overall, I think purchasing the lactate meter has been helpful for my situation or else I would be frying myself trying to hit the suggested interval paces when they seem to not quite fit the bill for me
The times in the spreadsheet were to generate 1km, 2km, and 3km which most can not handle to start with. I’ve always modified them down the initial principle of 3, 6, 10 mins and then build up the number of reps.
once you aerobically improve you can shoot for 4,8,12
