Maintenance for the week of March 25:
• [COMPLETE] ESO Store and Account System for maintenance – March 28, 9:00AM EDT (13:00 UTC) - 12:00PM EDT (16:00 UTC)
If you mean actual running and not sprinting, the only way out of this is to open the Crown Store. I was having the exact same thing just today several times (and until some months ago every now and then). Not sure what causes this..
