Sprint suggestions - what do they mean?

I have to say, I quite like how it works in practise, even if how it is explained on screen is not so intuitive: I think they have done it like this so that after the final sprint rep you don't get the 3 minute recovery when the next step is (say) a 10 minute cool down. If it repeated the 3 mins recovery after the final sprint rep, it would then be followed by 10 mins cool down, so you would end up with 13 mins cool down. I know when I set up reps like this as a manual workout, getting the difference 'programmed in' on the last repeat so there is no 'recovery/rest' on that one is a pain. So, for me at least, it works well from that point of view and now I know they do that, I find it easy to interpret their summary on a Daily Workout Suggestion. 

• You actually said the same: the logics of the workouts with anaerobic focus are fine, but the pre-workout summary is not. One understands the summary easily after doing some workouts, but not before.

Yes, but I guess the summary has such a short character count, it has to just present the 'key' element of the workout. The warm up and cool down, for example, aren't critical elements to understand the main thrust of the suggested workout. I find within these limitations,, the descriptions are useful and accurate enough. It's certainly a great additional feature to have from my upgrade from fenix 5s. 

It works fine for tracking sprint workouts with a pace target as long as you use a foot pod. I usually do my sprints on a track using the Track Run activity which further helps with accurate pace calculation. Of course you can't actually look at the watch while sprinting, but you can check right after that workout step ends to see if you hit the target pace or need to push harder on the next one.

You raised another question, that I was wondering a bit after my first anaerobic workout, namely the target pace.

Afaiu the paces shown are always the avg pace of the step of the workout.  Not the actual pace. Independently whether you are in a recovery step or in a tempo step etc. 

If you are said to rest, dont move and you are alerted appr. 5 seconds before the next sprint even if you immediately speed up it is tough to get the target pace as an average, too. So if I am asked to speed up 3:10 min/km, I can do, but the avg will be some between 3:20-3:30.

Do you say that the target pace is not the “peak” pace you have to achieve, but the avg pace you have to achieve during the sprint?

If so, I have to options: a) speed up a bit earlier b) dont care with the target pace, just make an all-out for 15 seconds, and I will get what I get as regards avg pace?

You're kind of missing the point with that sort of fine detail. The daily suggested workouts are just general suggestions to maintain fitness for average endurance athletes. They aren't so precise. If you're at the level where you're worried about hitting an exact pace within 0:10 min/km then consider getting a coach and following a real structured training plan.

That said, if you look in Garmin Connect it shows your average pace versus target pace for each step. Not peak pace.

That’s it. As you get stronger you develop an ability to reach max speed faster. As noted, starting early devalues the sprint.
