Is heel striking bad? I am not a runner, but I've practiced heel striking while backpacking to give myself more foot-stamina. Maybe there's a better way?

Yes, not only is it hard on your body but the energy lost in the strike you'd benefit from storing in your calf.

This is very confusing to me. I always thought absorbing the shock with your calf muscle would cost more energy.

There are more efficient modes of running that aren't really available when walking, and any experienced marathoner knows how to exploit this. It took me years of occasional running before it all clicked, despite more experienced friends having shared youtube videos on the subject. I'd always been running in a fashion more like a slowed down sprint when trying to pace myself. But that's not the efficient way, the eff…

I had knee and slight back pain, anf always tried to mechanically aim at the smoothest impact (landing on foot ball, ensure enough forward momentum) yet,unless a high enough speed, I found it harder on my joints. To the point where jogging heel striking like a newb felt nicer. I'm still dumbfounded.

Might be a function of modern shoes. I can’t heel strike on old or bad quality runners

Well, heel striking sends shocks through your spine, unless buffered via sufficiently springy shoes. If you have strong earmuffs, consider trying them while running, and you'll hear the shock if it travels up to your neck. Switching rapidly will probably cause injury, but I haven't heard about any sizable subset of the population being unable to adapt. Another helpful effect is that you don't need shoes to run if you…

Have you got some recommended videos? I'm trying to increase my distance and its mainly stubbornness that's keeping me going

There's a training program by a former Olympian that uses alternating blocks of running and walking: https://medium.com/runners-life/how-to-start-running-using-j... I've had good success with this strategy - it breaks up the monotony of long runs, and overall pacing is accomplished by changing interval duration instead of trying to maintain a precise fixed speed over the entire run. Unfortunately, I've had no success…

Couch to 5K (C25K) is another run/walk training program, which is very popular here in the UK. Even the NHS ( https://www.nhs.uk/live-well/exercise/couch-to-5k-week-by-we... ) promotes it. I started with a C25K plan in November 2020 and ran my first half marathon in October 2021. I'm looking at marathons now, it's changed my level of fitness far more than I could imagine.

I did a few 4 hour marathons in my early 20s, and in December I decided I was going to train for another one, after doing very little cardio for a long time. The run/walk approach has been great for me. I run for as long as I can, then walk 100m, run 400m… until I think I’m done. I’m getting through 10k in just over an hour now, and when I started I was struggling to mostly walk 5k.

I may start long jogging sessions to see if I can break the 20km threshold. Any advices?

In some endurance sports there is also the question of whether to use poles or not, on this subject last week I've seen these fascinating tweets:

Personally, I would say it's not even worth worrying about unless you're an elite runner.

I've been running about 10 years now, done marathons and ultra-marathons and I've have had my fair share of injuries. Not one was down to how my foot strikes the ground. Most of my problems were weak glutes and other muscles caused by sitting too much (developer lifestyle..) and incorrect footwear (in my case, too narrow).

Also, you'll find your run differently depending on how fast you run. On my fast runs, I do run on my mid/forefoot and on my easy runs, I'll be on my heel a little more.

I will say though, that once you reach a certain point focusing a little on running form will help. Things like leaning slight forward and trying to work on your cadence.

You're effectively using your calf as a spring damper. The energy stored in the spring can be released on your next step.

If you're landing heel-first, that same energy needs to be dissipated by your skeletal structure.
