recalculating distance changes everything before it in pr's

When using the recalculate distance it messes everything up before it.  Ran a marathon today where I lost gps a few times shows 26.06 .. when I recalculate it shows 26.30 which makes sense because I started my watch a bit back from the start. But when it recalculates it changes all of my previous pr’s from 100m to 10k to 1second and the half marathon and beyond are off now too. I reverted so it’s fine now but are there other ways to change this?

I would guess they meant the best efforts of the same activity where all changed to 1 s. To answer the original question: No, there isn’t any other way in Strava to correct the distance.

Hi ​@envisiondl,

this sounds like a bug… are you saying that recalculating the activity changed best efforts of previous activities?

I have used the “correct distance” on my yesterday's run and it worked as expected, it had added a bit of extra distance and slightly recalculated the pace, but my best efforts are untouched. 

When viewing the best efforts, you should see the origin of the incorrect PRs - which activity is it. Is it this marathon or something older?

Also, it might help if you include some more details - information about the recording device/app, link to the activity / activities, etc.
