@OutdoorMan I had the same a while ago. Well I always wondered why it was considered anerobic altough ZoneSense as well as heart-rate should consider this as aerobic or long-aerobic.
Long story short: I updated the pace-zones in the watch to values that correlate and afterwards it was correct.
If someone has an idea how it’s possible to control that (I’d prefer it would use the info coming from ZoneSense), it would be much appreciated
