Hi, i ran a 5k TT at 6:10 pace. Avg HR was 189. The last 2 miles (6:05, 6:24) and my HR was between 192-196. My resting HR is 47. Can i use this information to determine my LTHR? Or do i really need to do a 30min test?

Benito,

We can get 95%+ accuracy based on this information.

LTHR 193
Threshold pace 6:20

ah, thx David! That seems quick. If I’m understand this correctly, I should be able to hold threshold pace 6:20 for a 30-40min run?

Yes, I’m proposing that if you can do a 5K at 6:10 for 19 minutes, you can hold 6:20 for 30 minutes.
