It makes sense to clarify, that we should be talking about Threshold vs VO2 at about the same progression level. And assuming that’s the case - threshold at 5+ is an absolute torture for me. VO2 feels more like an interval, even when it’s 5min long, and I try to believe that I can do “just a little bit more until it’s over”. While threshold slowly but surely kills my desire to live.
As a result my current threshold level is around 3, while VO2 is at 6. Sometimes I must report threshold workouts as too hard/all out and TR would bring it down for me a notch. Maybe I should just HTFU though.
