Bug zone corsa
I want to report a serious bug in this VO2 max running session.
My critical speed is approximately 3:45/km.
This session, which includes 2-, 3-, and 4-minute intervals, should be performed in Zone 5 (3:45–3:30/km); instead, it prescribes a pace of 3:00/km—that’s Zone 7! 😂🫣 Meanwhile, another screen refers to it as Zone 6.
In a training app, bugs like these are absolutely unacceptable—this is the *foundation*. While features like HRV, recovery, and CTL are nice-to-haves, the absolute essential—if you want to compete seriously with other apps like Rest or Train or ATHLETICA.AI—is getting the workout prescriptions right.Train o ATHLETICA.AI è non sbagliare la prescrizione degli allenamenti

Hi Giuseppe, you're completely right, and thanks for the screenshots. This is the same session you posted in the Intervals.icu forum, and it's fixed and live now.
The cause: on days where the load target was more than the session could fit in the time available, a later step pushed the VO2max reps up to the session's overall ceiling (125% of threshold pace) instead of keeping them in the VO2max range, and padded the end with extra copies of the last interval. That's why you saw 3:00–3:05/km, and why one screen called it Z6 and another Z7. Both faults are fixed for everyone.
I've already replaced your 4 November session: the reps are now 110–115% of your threshold pace (about 3:25–3:16/km), the ladder is 4-3-2-1 twice, and the extra repeats are gone. Reopen the session and you'll see the new version.
One honest note: that range is a bit above the 3:45–3:30 you use for Zone 5. If you'd like your reps prescribed in your own zones, that's this roadmap item: Use your own tested training zones
