GoldenCheetah v3.8 January 2026 development build

[Ale Martinez]

See https://github.com/GoldenCheetah/GoldenCheetah/releases/tag/v3.8-DEV2601

Questions and feedback are welcome here, thank you.

Hi Ale,

I am on a MacOS (Tahoe 26.2) and this dev. build is reacting slowly...

The first start took really long (I thought it crashed), also the trends view does not load.

Activities are visible after the first start (I have approx. 2700 in the database), and I can easily switch to Athletes view.

But if I want to open either Planning, Trends or Activities afterwards, it does not work anymore.

Regards

Andreas

The first start took really long (I thought it crashed), also the trends view does not load.

Regrettably this is expected on Apple Silicon Macs, GoñdenCheetah is a x64 binary which is subject to Ahead Of Time Translation by Rosetta on the first run, this process can take a long time and uses a lot of memory, next starts should be faster.

Activities are visible after the first start (I have approx. 2700 in the database), and I can easily switch to Athletes view.

But if I want to open either Planning, Trends or Activities afterwards, it does not work anymore.

From which version are you upgrading? If full cache refresh is required, it can take a while on the first run and GC will be slow until it finishes (and repeated on the next start if you close GC before it completes), so better to leave it alone and restart when complete. See https://github.com/GoldenCheetah/GoldenCheetah/wiki/Cache-files-and-maintenance for details.

Hi Ale,

I came from V3.7 Build id: 5005 (Build date: Ost 17 2005 18:18:51).

Now back to the latest V3.7 SP1, which works fine.

Ok, thank you, then there should not be a full cache refresh involved and you can switch back and forth freely between them.

Main difference for macOS between both is the change from Qt 6.5.3 to Qt 6.6.1 which was not likely a good idea since 6.5.3 is LTS and 6.61 is deprecated, nor subjected to much testing.

I will revert that and trigger a new snapshot which will be exactly like v3.8-DEV2601 but based on Qt 6.5.3 for macOS.

[Andreas]

Hi Ale,

Thanks for the explanation and the feedback.

Always happy to contribute to the advancement of Golden Cheetah! :-)

Regards

Andreas

I have a similar experience on MacOS Sequoia 15.7.3. I've found that each view
works fine after I've selected "athletes" but switching directly between other
views doesn't respond. I can get around this by always going back to athletes
first.

Thanks for your feedback, there is a new binariy reverting back to the Qt version used for v3.7.1 in  https://github.com/GoldenCheetah/GoldenCheetah/releases/tag/snapshot, please give it a try.

[Steve Edmonds]

I have just tried the 3.8 DEV build on Mac Monterey (Intel). It starts
fine, no delays, no trouble switching but strange things related to the
plan view.
I added a workout to the calendar in plan view, it showed in the summary
but nothing showed in the box for the day.
I switched to train view selected the workout and completed it. The
Activity shows 2x in the activity view, once with the time I added it to
the plan view (without any data) and once with the time I rode it (with
all the ride data).
Both activities now show in the plan view with a little cup. The
completed activity has a yellow background, the planned activity has a
greyed background.

[Steve Edmonds]

I just updated to the new build (QT 6.5) and the activities added to the plan View now show when added.

Thanks Ale, this fixes the reported issue for me.

[Ale Martinez]

Thank you both for the feedback, I updated the v3.8-DEV2601 page with the new snapshot build binaries to try to avoid other users having the same issues, the problem of Edit menu missing on macOS when using translations should be fixed there too.

[Steve Edmonds]

I found the the v3.8-DEV2601 new snapshot working OK now. I am not sure on the state of development but have a couple of observations which might still be WIP.
The !Planned filter entry works well to remove future planned activities from the activity list. From my perspective I would like this to be a user configuration or check box. With the planner loaded with training I and planned activities showing I would never see any recent activities in the list without scrolling when sorted by date.

I am not sure if the intention is to turn a planned activity (workout) into a completed workout. At present opening a planned workout in train view and completing it creates a duplicate activity requiring manual deletion of the initial planned activity. There was a link context menu item but not sure how that would or does work.

[Steve Edmonds]

Thinking about it a bit more I can now see why it would be desirable to show planned and completed activities. I managed to link the planned and completed activities. I also notice that a filter applied to the Activity view (i.e. !Planned) also is applied to the plan view.

Is there documentation for the planning functions.

[Ale Martinez]

Hi Steve, yes, planned/completed activities is WIP and the idea of this build is to get early feedback from real users, so thank you.

When you import an activity we try to find the corresponding Planned activity and link both bidirectionally if found, the menu option is to allow for exceptions.

To keep Planned activities already completed will allow to compare planned vs executed both at Activity and Trends level.

To avoid Planned activities interfering with regular ones you can add !Planned filter at Perspective level for Trends view.

For Activities view you have to use the search/filter box in the toolbar, which we know it is not ideal since it is global to all views and it is not persistent, we need to to find a better solution and UX ideas are welcome.

Cheers, Ale.

I've tried yesterday the new build and it works fine (although still with my old problem and the wrong distance), but I had problems to sync the new ride to Strava.

I could see the new ride being recorded, however for some reasons, it wouldn't sync with strava.

Later today I'll try to give a better look.

Thank you for work on this,

Pier

[Jose A.]

I attach the images corresponding to the thread I opened about the pace units. This is how I get, in km/ for a running activity  

Even in Overview panel, units are in km/h. But pace zones or maximun vaues are in min/km...and I don't  why, total time is the same as moving time, while duration is the real moving time I recorded. All activities look like that.

[nick founride]

Amazing, thank you so much for the calendar feature. I am so grateful for this.

Ok now I understand, that is not specific to this version but a general feature of GoldenCheetah, velocity is km/h for SI units as expected and Pace in min/km is a different metric. Let's continue in the other thread.

It would be weird since nothing related to Strava has changed from v3.7.1 

[Manu]

Hi, tried on W11, no problems so far

Translations missing on the new features, no problem at all.

On calendar when you program a workout, you do it on train and later appears two activities for that day.

it would be useful a way to insert a plan or at least more workouts in a round. later they can be moved.

just thank for all the work done, gc always was good, now its acheiving what no other soft do.

Yeah, sure, I just hoped it would may be fixed.

I know why it couldn't sync, it's because it didn't save the ride. 

I remember it took a very long time to save it, but then it seemed successful.

When I couldn't sync, I switched between the download and upload tabs and in one of them 

I saw the new entry, but today, it's not there anymore.

I tried searching for any new file created yesterday and there's none. 

Thanks,

Pier

There is a "Repeat Schedule" wizard you can use to copy the planned activities from a range of days to a new one, see https://github.com/GoldenCheetah/GoldenCheetah/pull/4692

IIRC the current activity selected at startup is the latest realized activity in this case, but I added a feature request for this anyway:  https://github.com/GoldenCheetah/GoldenCheetah/issues/4809

[Pierguido Lambri]

Indeed it was there and successfully imported. 

I'll see to give it another try this week.

Thanks,

Pier

[Ale Martinez]

I am curious, why do you think it is Ok not to follow the forum guidelines?

 

I'll see to give it another try this week.

Likely you have to talk with other people, not me.

Because I looked for that the other day and I couldn't find it. 

Also I wanted to share (but I see I forgot) that, when saving the ride, it took a very very long time.

I see I didn't mention it, here it is in case it's useful.

To whoever wants to listen and discuss ¯\_(ツ)_/¯

I have now installed v3.8 and checking the possibilities that the new 'Plan View' provides.

Most beneficial for me is the PMC Trend Chart to see its evolution until an upcoming challenge, and I still have to find out how to hide planned activities in the 'Activities View' (different topic... I will find that out).

One suggestion / question / remark for the planning of activities:

I have seen the possibility to copy activities using a time range, but would an easier copy&paste be possible, such as:

click on an activity - copy it - click on another day - paste the activity directly, maybe using right mouse click or cmd+c / cmd+v?

For now you have to use !Planned in the filter box, we are testing a handier solution implemented by Paul in https://github.com/GoldenCheetah/GoldenCheetah/pull/4811, we likely update the release in a few days.

Copy & paste sounds useful to me. I will put some thought into this idea (IMHO copying more than one activity should be possible to prevent jumping between weeks / months). As my resources are currently bound by home renovations, it might take some time, but 3.8 should be possible. As soon as my concept comes into shape I will open a new thread to discuss the solution.

Great, for simplicity of implementation and use perhaps we could restrict copy/paste to one activity at a time and let multi-copy for the more elaborated Wizard, but it is your call.

BTW, at some point we should think about schedule import/export may be as an extension of the Wizard or a separate feature. 

Thanks for your work, Joachim, much appreciated!

[Joachim Kohlhammer]

Copy & Paste: If the multi copy becomes to complex, I will for sure drop it. But I will look into it

Schedule import / export: great idea, I like it. Probably we have to define our own format for this?

May be, I don't know what others do, ICalendar starndard for which we already have some support included in code could be a candidate.

I will merge and update snapshot builds in a few days for testing, but I will not retrofit for v3.8-DEV2601 due to the recent change in Python versions.

Dear developers,

I started to test this 38-2601 dev snapshot, and the calendar planning feature looks promising :-)

I have noted few issues as follows :

1) This issue occurs again : https://github.com/GoldenCheetah/GoldenCheetah/issues/4639

(it was fixed in Build id: 5006 Version: V3.7.1)

2) 

I cannot sync from dropbox :

when authenticating from Add cloud account > Acctivities > Dropbox > Add Cloud Wizard >

Service Credentials

Authorize

The "web based" authenication interface fails to send the 2 factor verification code : neither "Enter" keyboard key, nor "button send" works...

3) in the "plan" view, the tab "Expected PMC (TriScore)" :

- appears twice.

- I did not find the way to configure the date range for the abscissa axis

Thanks for your great work !

Regards

Gilles

It is weir since QWT has not changed from v3.7.1 to v3.8, I reopened the issue for tracking.

This would be a problem since we have no control over that window other than to update Qt version to have an updated internal browser... What platform are you using?

It is similar to Trends, show the lateral side bar to select a Date Range, you can also use View > Reset layout to get an updated layout and to add/remove charts as usual.

Right, the second one should be a PMC (Coggan) instead, I fixed the cloud version so View > Reset Layout should get the updated layout.
