I actually managed to get my “all time” fitness chart, but in order to generate it, I had to start with the 2 most recent years (2021-2023), and then once it was done, add the previous 2 years (extending the range to 2019-2023), and then another 2, and another 2, until I finally got down to 2010. Took about 15-20 minutes in total to generate it.
I feel like there’s something in the app that falls apart when it has to load more than 2 year’s worth of data in one “request” by the user.
You can use the search box on the calendar page to quickly find and navigate to activities by name or #tag:
Activity tags can be captured or assigned from a workout when one is paired with an activity.
If you try and load 13 years worth of data on the calendar page, activity list view or fitness page the app will struggle. That’s a huge amount of stuff to fetch from the server and render. All the activities are sent back via web sockets. I think the buffers on the server fill up before the data can be sent to the browser which is maybe why you managed to get it to work by doing a couple of years at a time. I might be able to fix that but the app will be slow with that many activities.
This isn’t something I have tried to optimise for because its not something people do often 
You can get your all time power curve on the /power page. That is computed server side so is fast.
Anyway let me know how you get on. I haven’t used Today’s Plan much so I can’t give you too many pointers. One thing I did like of theirs was their power vs HR plot. I built a better one (IMO) in Intervals.icu (see /compare page). I managed to get a little fitter in 2023 vs 2022:
It sounds like you might be a software developer? If you know some Javascript you can extend Intervals.icu in many places:

Happy New Year! 
Aha! I never thought to look under “OPTIONS” (in Calendar view only) for the kind of “full search” I’ve been hunting around for, but this appears to basically be calling that /activities/search?q=OLH endpoint and showing the results (unordered name/date only) very quickly over “all time”.
My first instinct was to try this 
field in Intervals’ left sidenav, but I still haven’t figured out what this is for (and didn’t manage to find an explanation in the Guides; no handy tooltip on hover over the icon either 
):
Now if only the results from “OPTIONS > Search” could be ordered… and if I could see some stats for each one, similar to how it looks in the “Activities” page in list view:
If you’re curious, in Today’s Plan, they have this toolbar at the top which has this icon
Clicking it gives you this “Quick file search” modal (it floats above the Calendar and takes up about 95% of the browser window) where you can filter by activities, any date range you want, and some text to search activity names including notes/descriptions (something which Intervals doesn’t search, AFAICT):
From there, you can click an activity to open its details in a modal so you can come back to your search, and it’s easy to compare a few things just by looking. (Within an activity, you can load in another activity to compare in Analysis view.)
Since Intervals doesn’t appear to search what you call a Description associated with an activity, I’m going to use the API to reformat all my activity Names to include climb/hill names.
In Garmin, those are all in activity descriptions because Garmin activity titles/names are limited to 68 characters (and the activity import of Garmin history into Intervals didn’t include descriptions, so those are all missing in Intervals anyway).
But at least in Garmin, an “all activities” search includes both titles and descriptions so I can still find everything over there (though I rarely use Garmin Connect for anything other than building/syncing routes and setting title/desc in case I ever have to sync history elsewhere, like I just had to do a few days ago with Intervals).
That is a cool chart! I like your version of it. Easy to interpret!
Yes, sir! I’m amazed at what you’re managed to build here, not to mention all the extensibility you’ve added to it via the custom fields with JS and the API. 
I’ve already customized my activity view to give me fields I previously had in Today’s Plan (and more) which I found so handy there:
The first search screenshot you posted, searches other athletes which you’re following/coaching.
You can set plenty of filters in the activity list view. Name/ Not Name/description/tags…
Isn’t that together with the date range an alternative to your search question?
Got it, thank you! 
It would be if only it didn’t suffer from the ~2 year max data pull issue (2 years with my data; might be more/less with someone else’s), which I assume is related to the use of web sockets to pull the data from the server, which Dave mentioned earlier.
The Activities List View was my first go to. The first thing I did was set my date range from Aug 20, 2010, to Dec 31, 2023, and then the app fell over. I did also set a name filter to find rides by my coding system, but since those go back further than 2021, when the app had loaded data from Dec 31, 2023, back to around early 2021, it just stopped. The spinner in the top/right corner of the list view kept spinning indefinitely and nothing more ever loaded.
So the OPTIONS > Search feature (Calendar View only) seems to be the only way, currently, to do a quick name-based search across “all history”.
I just wish it would show results in a way I could sort and filter just like I can with a relatively small subset of data in the Activity List view, and that it included descriptions, not just names – if at least with pre-computed data found in FIT files like total ascent, moving time, distance, speed, load, etc (not necessarily activity streams or things that require further data crunching).
I see now…
I only quickly scanned your former post without fully understanding.
Sounds like a challenge…
How many activities do you have?
I start from 2017-2023, then once it’s refreshed I add 2012-2023 and then finally 2008-2023.
2879 activities 2008 - 2024.
Once it has pulled all the data, the second time I open it, it’s much faster.
The searching by name is very quick.
Running Chrome on Win11 (i7, 8GB ram). WKO has a similar problem, with large amounts of data. They advise to let it update all data, then run the various reports.
I have about 4600 activities from Aug 2010 to today. The app tops out at around 1255 activities, AFAICT, in the Activities List View.
@stefcameron can you give this a try, and see if your activities load quicker.
Create tabs for different activities types (see my example).
Tabs on the activity list view - #14 by Gerald
My RACING tab is relatively short, compared to all ride, runs, all activities, so loaded all races as quickly as it takes to change start and end dates (<10 seconds).
I then clicked on the ALL tab, and it took another +/-10 seconds to load all 2672 activities. This is significantly faster compared to opening the ALL tab first.
@Gerald Thank you for thinking about this and for the suggestion! I gave it a try, but it makes no difference. I never got past loading the runs, and that never finished either. It took 5 minutes just to load 67 runs (and I already had about 15-20 of those loaded) dating back to July 2022.
There are hundreds, likely close to 2000 (I have ~4600 activities in total, more rides than runs).
It’s just not workable.
I think what’s needed is a dedicated Search View that uses the fast API I mentioned that returns results based on pre-calculated data already stored on the backend (since I think there’s a lot of data crunching that happens on the frontend that would slow things down significantly with the number of activities to load). I believe this is the API used in “Calendar View > Options > Search for activity” because that is super fast and searches everything through all time (this search took <1s):
But it doesn’t show results in a workable table with at least activity time, distance, total ascent, etc., and it doesn’t search descriptions, only names.
You can see in that list, a search for Old La Honda (famous climb in the SF Bay Area) yields results back to 2012/2013. I never find those in the List View because they never load (unless I really persist at it by gradually increasing the date range, but it takes 15-20 minutes).
And the search should also include descriptions so I don’t have to stuff everything into the Name and end-up with super long names like this (because I like to search on hill names; e.g. what are all the times I did this climb?):
Have you tried exporting to Excel, using the API?
I know this defeats the point of using one application, but it’s as simple as click on “refresh data”.
MacOS is limited in its use of Excel, but Windows versions work seamlessly.
No, I haven’t, and that would be super inconvenient for regular use. I’m not without solutions to this problem, but for a paid app (one I choose to pay for/support), I see activity search (regardless of date) as a core feature.
For now, if I have to find something, I can go to Strava or Garmin Connect since they have search functions that are fast and can search everything (and thankfully, I’ve been diligent to keep those updated over the years, exactly for this reason I’m facing now).
The downside to these other “solutions” is I can’t (without a lot of time on my hands) easily load up the activities I find there into Intervals.icu because I don’t know the activity IDs. If I knew the IDs, then I could at least copy/paste them into the URL and load them directly (but I don’t want to have to export to CSV every time I want to know an activity ID either; I want my cake, and I want to eat it too! ). And then even if I could do that, I wouldn’t be able to compare them.
It’s just a hard sell for me, coming from Today’s Plan, as I detailed in my linked feature request (see one of my previous comments).
But that’s not to take away from everything else that’s really awesome in Intervals.icu. Overall, and for many reasons, it’s a fantastic app and I’m glad to have found it!
Hi @stefcameron, thanks for your info above, I actually have seen this also with over 10 years of data. I have created myself three Seasons for 4 year chunks which seems to be working well for me . i.e.
Settings > Seasons
Then on the Activities List page I select the Season and then do my search
Thank you for the suggestion, @Wazc23 Seasons are related to lots of measurement/comparison features in Intervals so even if this worked, it would mess up the seasons I already have configured (I don’t think Intervals allows for overlapping seasons either, so I couldn’t define seasons like these that overlap the seasons I already have). And even if this did succeed in loading activities faster for some reason, it still isn’t a solution to activity search because I still can’t search everything. I’m limited to searching within batches.
I am busy adding a text search to the activity list view. This replaces the date selector when enabled. Will take a bit of time to get this done.
Sounds great! Thanks for taking it on!
It’s live now. I will do an announcement and provide more details once any initial bugs are found.
Thank you!! 
Just tested it and it seems to work really well. And includes (searches) the description too, awesome! And all configurable with any column already available in the List View.
