I just ran a 8:00 mile my HR was 129, guess my PR MILE.

I'll be honest if your right. But guess what my PR mile is based on my HR being 129 off an 8min mile.

Feel free to add YOUR HR after doing 1 8min mile (Not a 8:30 or 8:50, an 8min mile)Add your PR mile as well in correlation to your 8min mile.

7 hours

Great guess.

That's really hard to guess without at least knowing your age.

I'll guess you're early 20s. That means for you an 8:00 mile is about 65% heart rate max (roughly).

Since that's within a low-intensity range, it's very difficult to tell what your mile PR would be. It also depends on the terrain you ran on and the amount that you were hydrated.

I'll shoot into the void of darkness with very little to go on, and say 5:00 is your PR.

4:38

5:20

i'm 29

I was running 6:58 on the treadmill recently for 8M at a heart rate of 126 and my mile pr is 4:40. So, I'll guess that your mile pr is 2/3 of 8, which is 5:20. But I have my doubts about whether this would have any accuracy, since it depends on what shape you are in now, whether you are healthy, and whether you are trained with major or minor miles.

8 minutes ( ͡° ͜ʖ ͡°)

this is obvious. 4:12. a HR of 129 is lower than you think.

4:34

My HR is 100 running 8m miles. I could probably squeeze out a 4:30 mile right now. My HR would get up to 160 for that effort.

Some of you are forgetting one crucial fact: we don't know how old the OP is.

A 40 year-old with a 129 HR is very different from a 20 year-old with a 129 HR.

5:00 YOU SLOW POS

DNF

Actually, some of us read the post that's six above yours.

I would say 4:30.

It's hard to predict because some people are stronger aerobically, while others are a stronger anaerobically. I'm the latter. When I was in PR shape I would have 130-135bpm for 8min pace, and I was a 4:05 miler.

It probably doesn't mean much.

After a 8min mile my HR is about 118-120 and still I doubt I can run a sub-5 mile right now..

When i am warmed up my hr is 145 at 8 min pace. At 129 I would run ~9:10/mile.

I can run a mile (on track in race) in 4:20. You should be able to run 3:46.9 for 1 mile.

Is your name Alan Webb?

Can't be webb. His first post on this site was yesterday. Momentous occasion!
