Is a 12 min mile jogging or walking?

Running is an action, not a pace.

If both feet are off the ground at once, then it isn't walking.

Yes but is he wearing super shoes?

I do a fair amount of walking for recovery in my training. The fastest I can walk is right around 14:30/mi. 12:00/mi is definitely slow running, not walking.

4 mph is top end speed walking

My typical walking pace is 16 minutes a mile, my brisk "tempo" walking pace is 14:30 a mile and my jogging pace is 12:00, my tempo runs are about 10:30.

Definitely jogging. Still well under 6 hours marathon pace.

For an 80 year old.

You realize you could do "infinity" minute miles and be running if you wanted to. It is called running in place. Running and walking have nothing to do with pace and everything to do with the mechanics (form).

You knew that though and I assume this is another one of the "pretend to be dumb" threads that are so popular these days on Letsrun.

Have done both; 12-minute miles is extremely slow running or extremely fast walking. It is difficult to run that slowly or walk that fast.

12 minutes is TORTURE pace.

Biomechanically too fast for walking...it hurts.

Biomechanically too slow for jogging...it hurts.

It's hard to imagine someone choosing to ambulate at that pace on purpose. One of the most painful things that you could possibly do.

I don't agree. Most of my running is at around that pace on trails and a lot slower than that in the mountains.

Hmmmm....well I guess I'll have to take your word for it mountain man.

I do all of my running on a boring flat path and 12-minute mile pace is the worst of both worlds. Too slow for jogging and too fast for walking. I call the Devil's Dong Pace.

12 min pace average here, but looks like fun.

Meeting up with Simon in Arêches and finishing with Jess from Plan Villard - Jim W.'s 19.2 mi run

Jim W. ran 19.2 mi on Nov 7, 2022.

I absolutely agree with you about the discomfort in maintaining that pace on a flat. If I was going to average that pace on a flat. I would mix running 10 minute pace and walking 15 minute pace.

Yes, I stand corrected. I based that claim off of a quick perusing of google, but I remembered that 4 mph is somewhat of a brisk walk for myself. I would say 3 mph is not quite casual (no effort, zoned out, looking at phone) but not quite speed walking, I would describe it as what our teachers would call "walking intently with purpose" to get to class on time.

My fastest walking when I was injured was 16 min mile.

Quicker than that would've been easier to jog

I’m 56 and coming back from meniscus surgery. After only running a total of 250 miles in 2022 , I’m starting from scratch staying in Z2 for 45-60 min 4x a week.
This morning my pace was 13 min/ mi- I was jogging and it definitely felt easy but was able to keep my HR down at < 70% max.

Felt great afterwards and did 6 uphill strides to finish.
Just happy to be out there and know the way back is lots of easy miles
