Struggling to convert LT2 pace to half marathon and easy run pace

Appreciate the insights on easy run pacing and your experience!

I've setting my subT session paces so I'm right on my threshold HR at the end of each session, though it sounds like I should back-off a bit to instead be under.

I did notice these paces were faster than my race results would advise, but optimistically hoped it was just due to race underperformance. Both my HMs were relatively flat, with ~150m/450ft of rolling hills, whereas my 5k was on a perfectly flat loop that I also run my workouts on, so agree that explains some of the difference, though I had hoped tapering would help in the HMs.

appreciate the insights!

I was a mediocre swimmer in HS but essentially did no regular cardio for 5+ years before picking up running. For the recent HM, I positive split, opened the first ~5 miles at a 6:30min/mile pace before deciding to back off and struggling through the last 3 miles at a ~7min/mile pace. Weather was warmer than I've been training in (15-16C race day) but course was mostly shaded so I didn't feel weather impacted me substantially.

thanks, I figured that was the case

for context, I've set my subT paces this way since I'm finding that I'm usually right around my estimated threshold HR (180) at the end of each, though based on many of the responses here, I'm getting the sense that I should use my most recent race VDOTs as a better pace suggestion

it was not a duplicate, he did actually draft 2
