hot take: most people’s zones are wrong because their ftp is from a test they haven’t repeated since
everyone treats the number from their one ramp test in march like it’s carved in stone. you’ve either improved since then, so your hard workouts are too easy, or you’ve detrained, so your “zone 2” is quietly zone 3 and you’re wondering why you’re always tired, a stale ftp is worse than no ftp because it comes with false confidence
When did you last test vs when did you last change your zones, be honest
