This feels like a very basic question and that I am missing something obvious, but the “Add Interval” option…how does it work? Pressing “A” or the “Add Interval (A)” link does nothing. I have tried in many activities, with or without a zoomed section all with the marker somewhere on the activity. I’ve tried ‘a’ and ‘A’ too. Nothing results from this.
What am I missing?
Thank you.
PS Using Firefox 79.0
It should add a 30s interval wherever the marker is and then you can expand it etc… Just tested on Firefox 79.0 on my Mac and it worked. Could you please msg me a link to the activity. It is possible there is something wrong with it that is causing interval adding to fail. Tx.
Aha. All of the timeline is covered in WORK intervals so that’s why you can’t add more. You should probably delete the Z1 intervals which will mark them as recovery.
I should also add than intervals in Intervals.icu do not overlap which is different to some other tools. I made that simplification very early on.
Right. Ok, this is where I went wrong. I assumed you can overlap intervals. Hmmm that is a shame. Can that be user configurable? Even if needing the user to enter the start and end time stamp.
Thank you.
Unfortunately its not easy to e.g. if you look at how the intervals are rendered (bar right now height of all charts). I would need to add “secondary” interval display with lines under the charts or something.
What you can do now is zoom on any part of the chart and interval stats are displayed on the top left. That’s not what you are asking but might help for some use-cases.
Thank you.
Yes, that is what I have been doing for now.
Thanks for your hard work with this project.
Does it mean we have to remove the “work” interval in the “interval data” view and then use “add interval” to manually add the intervals we are interested (eg. see my activity https://intervals.icu/activities/4313744228).
Thanks
Yes. Or you can drag one of the edges of that interval over the other to delete it.
Last night, I was trying to create intervals, but when I tried to have them in sequence by dragging the end of one to the start of the other, the UI joined them into 1 interval. It looks like I can only have this scenario if Intervals detects the intervals.
Am I missing something?
You need to do this on the “Interval data” page rather than dragging the edges. You need to keep a 1s recovery interval between each work interval. Click the work intervals and edit the start and/or end indexes:
Thanks. I’ll try that. I think I was using my phone and couldn’t find the “interval data” page.
Why the 1s gap between intervals?
Thats a limitation of the intervals edit functionality. If two intervals are exactly next to each other it will combine them. Its something I can fix in future,
To add here, is there a way to have intervals (dot) icu look at ONLY the first half of a workout? E.g., as you can tell based on the image the 1st half is the actual “ride”, the second half (including the break) is a easy spin. Would I want to delete an interval and then select the first ~60 minutes? Thanks!
I have added that to the todo list.
Awesome, thanks David!
Hi all,
I’m new to using this tool, and relatively new to cycling as well to be honest. So I find myself with the same basic question that David Ward had 2 years ago.
I just recorded my first activity- Intervals.icu
No HR or powermeter, so am trying to manually add intervals by hitting ‘A’. I see a “~ No intervals detected” message every time I try this, so I know I haven’t broken the ‘A’ key in desperation. There must be something else I’m missing here?
Thanks in advance! 
What traces do you have if there is no power or HT? Only Speed/Pace?
I have never tried it with only speed/pace, but I would think that it should equally function by placing your mouse cursor on the speed/pace chart (you should see a vertical line appear) and then press the A key on your keyboard.
If it doesn’t, post a screenshot with the traces you have and also a screenshot of the Activity Intervals page.
