Hi ​@Simon Sandbakken,

can you still see it in the notifications list? That should work as a shortcut/bookmark to the ride. And would allow you to see what's possibly wrong. 

The other day I saw a similar situation. Someone couldn't see a ride on their profile, but luckily had a link. And it turned out that the activity got somehow damaged, and the duration was greatly inflated - so that the end timestamp was far far in the future. Which is why Strava wasn't displaying the activity - and it would only appear once the end date & time had passed. - I’m not saying that the same happened in your scenario, but it's possible that it's something similar; the fix would be to delete the corrupted activity and re-sync it from your garmin again. 

Ah, yes Strava shows elapsed time as 64000 hours.. will try to delete and upload again

Hi again - ok I think I found it and yes, the elapsed time is crazy  

here's the link (it's a public activity but if you're not comfortable with having the link here, please just say so and I’ll edit this & delete the link):

(I’ve looked up your profile using your name, and since I knew I’m looking for missing ~70k, I checked your best efforts… and voila, it was listed as your 50k best effort)

Edit: ok I type too slow
