I’m not sure if anyone else has the problem with Strava activities having gigantic (miles long) “spikes” in their activities which make my life map look wrong 
Unfortunately, I’ve tried using the “resync” function in citystrides, but it says that “there are too many tasks running, try again later”
I’ve tried doing this for months and it hasn’t worked a single time, and I’m not sure if anyone else has this problem.
Yeah, resync pushes jobs to the same queue that city sync uses & that’s been a beast lately … I’ve been working on this problem since October 2025.
There’s a bit of a problem in how to handle this, because I either block the action (how it is now) or I allow it but it takes a long time. That wait can be confusing, which can result in people taking incorrect & drastic action like revoking access (which only deletes the account and all its data, it doesn’t resolve any issue).
I already have a 5/day limit on resyncs, and I already have phrasing that sets expectations (“The requested Activity is now being resynced. This may take a long time.”), so I’ll adjust it to remove the hard block … I’ll probably get this out sometime today. I’ll try to remember to update this post when it’s released.
Just in case - have you edited the activities in Strava to fix the ‘spikes’? If you haven’t fixed them there, then resyncing isn’t going to accomplish anything.
