Hi ​@Karlo Maslać,

there’s a limit on the birth date changes, try again in 24 hours, it should work then. 

Yes, you can change your age on Strava… but unfortunately, you can’t celebrate your birthday every week . Strava lets you update your date of birth, but they’re wise to people trying to be 25 today, 45 tomorrow, and back to 30 for the weekend group ride.

So if you want to appear younger for those new PBs, or older to impress people with your power numbers — go for it, but you'll need to wait a bit between changes.

And hey, being able to tweak your age every now and then… keeps life interesting, right?
