Interval detection

[MarkyMark58]

I’m sure this is my error, but why doesn’t intervals.icu detect all the efforts in my structured sessions. Here is an example from yesterday:

Intervals.icu

We can’t see your activities like that. Next time post a screenshot please.

But probably, the Use Laps option is not enabled and then Intervals uses its own algo to hunt for possible efforts.
On the Activity Timeline tab, go to Actions at the bottom and choose Analyse with these options

If that results in what you want by default, change it on the settings page per sports category

There’s a thread explaining all the different ways of defining laps/selections/intervals here

Intervals vs Selections & Activity Zoomed view

This is a follow-up post regarding intervals in Intervals Getting your intervals from an activity can be done in several different ways: Intervals can detect efforts in a data-stream following an algorithm. This is in fact how Intervals started out at the very beginning, hence its name. Efforts can be detected from Power, HR, pace. This is an automatic process and the algorithm will in most cases find intervals from a single uninterrupted stream of data. This can look a bit chaotic if …

Many thanks. Your initial suggestion gave me exactly what I needed

Sorry for being dim, but do I need to uncheck the “keep all laps” box in settings?

@MarkyMark58

do I need to uncheck the “keep all laps” box

Depends on the desired behaviour.
Keep all laps will result in every part of your activity being a lap. Work and rest intervals will alternate. That is desirable if you do Work - Rest - Work - Rest…
But if you do other sequences, like over-unders for example, you should have 2 adjacent Work intervals and then a rest. In that case, it is a bit more work afterwards to define the exact laps.

Although @MedTechCD and other users have helpfully pointed out that we can use the Settings → Use laps for intervals option to avoid automatic interval detection in activities, I still have many issues with unstructured activities where the lap button was never pressed.

See, for example, the activity below. The athlete left home, completed a route, and returned. I know I can use clear intervals, but it seems like a waste of time and resources to have to do this dozens of times a week.
Is there any way to avoid interval detection in activities without laps?

Yea something is still up for me. After these screen shots I tried several iterations of the “Action”-“Analyse” no change. “Remove”, removed them. “Use Laps” brought it back to to just like the screen print again. Bothe Garmin connect and Strava have all the intevals to within a second. FYI I pull in from Strava. I’'ll play around with it more.
