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?

LTHR 193 Threshold pace 6:20 David December 3, 2020 at 10:13 am #9473 benito1xParticipant 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? December 3, 2020 at 2:17 pm #9476 David WardenKeymaster 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.
