From what I've read, it seems people who are very aerobically underdeveloped have a big pace range in the top-end of their heart rate. The heart rate spikes harder at lower efforts and relatively less the harder it gets.
The longer the duration, the harder the spike gets if it's not truly easy. And at a certain duration medium effort blends awfully close to race effort heart rates. I can be at 180hr without working anywhere near a hard effort.
This is probably true for most runners at 5k, 20 min and slower. They probably don’t realise this, unless they wear an accurate chest strap, and pay close attention to hr. They may look at an inaccurate average hr from the wrist at the end of the run, and get a false picture of how hard they ran.
Maybe it's not how physiology works but it's how running can work. You start running something like 8:00 pace for a bit. You get tired and walk. You feel better and run something like 8:00 pace for a bit more and keep doing this. Eventually you'll adapt to the pace and won't need to walk. It's actually a form of interval training.
No one was a stronger advocate for slow running than Ernst van Aaken. Before he lost his legs he and his son ran 10 km after work each night in an hour. But his son told me they did not run a steady 6:00 km/10:00 mile pace. They ran faster than that and stopped to walk slowing the overall time to an hour but with all the running being faster than that.
This can work to an extent, especially on hilly routes, and there is nothing wrong with walk breaks on an easy run. But, generally, if you are having to run your easy runs as intervals, this is an indication that the pace is too fast,
I wouldnt say you hammer them, but if you have to ask yourself that question its very likely a bit too fast. You even describe it yourself - 'not always comfortable' shouldnt be used when doing an easy run... easy is a feel... mostly a feel that makes you wonder if you even trainined. Also i agree with the if you cant run like this every day or feel fresh for fast running you have to go slower no matter what ypu think is right, eg i run my easy very often pace between 830 and 9min despite running around 16mins for the 5000!!! Many local runners cant believe this but its whats needed for me to be feel recovered for workouts and hitting some decent miles, even running every day....Keep them at 1-2/10.
If you run easy with correct form and hitting fast speeds multiple times a week your stride doesnt get compromised at all! Focus an forefoot strike and a light bouncy feeling, coming from your hips. Never strain or 'muscle' your way through, always use ypur elastic energy. When running slow like this it feels almost like using no muscle force at all, a bit like relaxed jumproping.
I assume ypur younger which means you shpuld be running slower than someone running the same times but is way older and more experienced like some posters here. Its because lifetime miles and efficieny matter and with age the top end range fades, but lot of older folks keep a better percentage of their racepace than their younger counterparts...
Other than doing like 5k 4x/week all out, you can do whatever training you want at 120mpw. You are so far from any limits that it doesn’t matter.
If I run my easy days any faster I'm not recovering and just digging a deeper hole. So there is a limit.
If I didn't do any track workouts or lift weights I would probably agree. There's not much volume to hurt yourself doing only 2-3 hours of running a week but it's enough to get hurt if you're not recovering from the hard stuff in your routine.
I would like to run easy days faster but I can't or I just end up running my hard days slower. Maybe removing "hard" entirely would be the best way and just do a lot of easy and threshold runs so recovery wouldn't be as needed.
Give us this 12mpw schedule where the hard day are so hard that you need to run like a snail to recovery…..
I have seen 15-20mpw training plans. They hammer every day….
any fit adult male should be able to run 5/6 times per week and be able to run under 17mins with 6 months of consistent training (if starting from ground zero), 3 months if a regular runner

And you aren't training the right energy systems.
I don't see what people find so abhorrent about low-intensity running.
Every good runner in the world does a hell of a lot of it (most do 80% of their weekly volume as low-intensity).
So, why do so many try to avoid it - or argue that it's of no benefit?
Just stop being so self-conscious and train properly.

There are different ways to "train properly." Running a faster pace with recovery breaks can be a form of low intensity training. Peter Snell told me that if you're looking to turn your fast twitch fibers into slow twitch you need to be running not much slower than 7:00 pace. I had a lot of questions about the arbitrariness of a flat number like that with no allowance for other factors but he was convinced that you had to be around that pace no matter what. I asked him how people who were pretty close to all out at that pace were supposed to train and he said they needed to do intervals which would not be that different from what van Aaken and his son were doing.
I know HR training gets sh*t on all the time, but the an HR in the 137-145 range is about right for me when it comes to easy training. I check my HR every 15-20 mins to make sure I'm in the ballpark.
It has the benefit of keeping effort consistent in different weather, terrain, various treadmills, and across all levels of fitness and even cross-training.
Going by feel doesn't work great for me. If I'm coming off a rest day and feel refreshed, I almost always run my easy runs too fast.

That is an interesting perspective. But, even if it is true(?), should that be the objective of an easy run?
HRE, very wisely, often comments that most runners do not run enough, and would improve just by running more. Running more mileage, both consistently and sustainably, needs the easy runs to be kept very easy.

I've lurked on here long enough to know that a) you know what you are talking about and b) have a ton of experience. So with the caveat that I don't mean this to be disrespectful in any way:
I don't disagree with you, but most runners are too stupid and inexperienced about training to do what you/Snell describe. 99.99 percent of runners will screw up an Igloi-style workout of 7:00-pace 100m "on" and 11:00-pace 100m "off" or whatever it is.
Far simpler to just tell them to slow the eff down on their easy runs.
I may get downvoted to oblivion for saying this but I don't think anybody should be running slower than 8:00/mile.
If you're a decent runner and 8:00/mile is easy for you then great.
If 8:00/mile isn't easy for you then tough luck, keep running at 8:00/mile or faster until you improve and it becomes easy for you.
I agree.
As I said in an earlier post I ran similar time to OP for 5k when I was 65-years-old (19:45).
I was barely doing 30 miles per week. but in between interval sessions I would would do recovery runs of 3 to 4 miles between 8-8:15 per mile.
In my mid-50s I would do a 1 hour 40 min run between 7-7:30 per mile. and still recover enough to do interval sessions.
A lot of this gets confused with what elites do in the way of supplemental miles with their second run of the day, and even then not all of them would shuffle around. For example Steve Ovett in base phase would often run 10 miles twice in a day, and both were under 6:00 miling.
Yeah, but Ovett also had some 5 milers in 35 minutes. So just about exactly half as fast as his 800m race pace.
Arthur Lydiard: Ovett, of course, admits he does big mileages. But if you think anyone is going to succeed on what Coe says - 50 miles per week of anaerobic running - well, I'm sorry, I just don't believe it. Source Runner's...

Now we can get into exactly what we mean by an easy run. I would define easy runs as what you should do most of the time if for no other reason than to be able to run as much as you need to. One way to do that is to run slowly. Another way to do that would be break the runs up with a bit of walking. Again, van Aaken was absolutely sure that nearly all of your running needs to be easy but also advocated walking breaks during many runs. I've seen profiles of the training of a couple of his athletes from the early 60s. They ran LOTS but there was nearly always some walking during those sessions and part of the reason for that was that it lowered the effort levels of the runs.
After upwards of fifty years looking at this sort of thing I think the main thing you need to do to run well is make sure you're running enough, whatever "well" and "enough" mean for you. If fairly slow running makes that more doable, do fairly slow runs. If walking occasionally during a run makes that more doable, walk a bit. Or do both on different runs.

Thanks for the respect. And I won't disagree with you completely. Telling people to slow the eff down can be a lot simpler. But not always anymore. I see threads here from people runing mid twenties and up for five km asking about what zone they should be in and when and how much time at a particular threshold and that's not simpler.
And there are many people who just feel awful and awkward at real snail's paces, let's say 12 minute pace just for the heck of it. So we tell two people of similar age and ability to try to get to six miles a day. One runs at about a 9 minute pace and has 18 minutes of walking in the rest of the time and the other runs a steady 12 minute pace. To me what matters is the six miles, not how each got there.
This can work to an extent, especially on hilly routes, and there is nothing wrong with walk breaks on an easy run. But, generally, if you are having to run your easy runs as intervals, this is an indication that the pace is too fast,

They’re looking for a short cut. If they just find the right workout they won’t have to run so much.
The reality is that distance running training is not glamorous. It’s mostly about grinding out a lot of miles.
Watching runners at all levels over the course of many years, I’ve seen nothing to disprove Lydiard’s “Miles Make Champions”
