20 miler @ 7:28 PACE / HR 156. 2nd best 20 miler ever.
I've learned that about 155 HR is my breaking point in long runs (over 16) and 165 HR in my medium long runs (10-15). Speed is not the issue, I can run 6's any time I want throughtout the medium or long run but know I will hit the breaking point after a couple of miles if my HR hits those critical numbers. Once I have hit those numbers I can't reverse the effect.
I need to make sure and run my marathon by HR effort and not mental effort or I will overrun my physical ability.
It's hard to read the below but the first 5 avg was 7:46, second 5 was 7:31, third 5 was 7:19 and last 5 was 7:17. A few low 7's thrown in there but no 6's.
