Firstly, congrats for getting this done. It is tough with the short recoveries. It’s intended as a threshold so perhaps we just went over that LT2. Although likely that was only from rep 11 onwards. What we are ultimately looking to achieve is get just under LT2 and stay there for as long as possible, hence the short recoveries, so our HR stays right where we want it. I would imagine looking at your max HR that your Garmin threshold Zone (4) is max at 170ish. Thus predicted your LT2 at 170. Sorry if this is all quite a lot of detail but if we go down this route, which I think can be beneficial, it’s worth getting this right now. When I did this session I set it up on my Garmin so the second I went into Z5, it alerted me, so I was able to then slow down. Looks like your last 6 reps, were probably all in Zone 5 or certainly top end of Zone 4 (referencing Garmin zones here not PB Runner zones, again sorry for the confusion). So in summary, yes probably working a bit too hard and why it felt so tough. Would be interested in more feedback via a message in terms of which direction you would prefer to go. More threshold work? (if executed right hopefully they won’t feel this tough). Or stick with more traditional workouts? (5K pace). All that said, great effort here and probably the session which will have had most positive impact on your fitness for a while.
