To say "simple" is a bit misleading. Forward lean requires months of strength training and practice to achieve.

I developed a bone spurs on my Achilles just got treatment for it and been running again on mile 5 now. Thank you for this info it means the world to me and give me strength mentally to keep going peace

Great tips. Thank you. 😊

WOW THANKS now i cannot get hurt but THANK YOU!

Very helpful. I’ll study this

Thanks James for this video. A timely reminder for me and tips on how to increase stride length which is what I need to do. I will focus on comfortable knee drive. This might help me not look and run like an old plodder! 😊

With great respect, isn't the '90 degree angle' thing utterly disproven? Even the clips you show of "elite runners" show their arms at an angle far below 90 degrees. Mr Kipchoge's arms for example are around 50 degrees. Similarly the 'arms 'swinging forwards' thing - again, in the clip Mr Kiptun's arms are not 'pointing forward, they move across his chest, as is the case with many current champions.

In order to prevent injury and run safe for long distances are form with mid-foot, correct? while one foot directly touch floor when upper body is above, bring other foot closer to repeat strides to reduce spread out/ cramps while running🤔-> which happened during my last full marathon races I've been participated

I am finding that when the knee drive is sufficient, it will feel like I am either lifting my knee too high or just high enough. The foot strike is feather-light because the hip flexor is still engaged giving a controlled foot lowering to the ground after the knee drive is complete. My knee drive foot begins to skid the pavement during the drive if the hip flexor is not lifting knee high enough, or if I let my leg pendulum forward without using hip flexor.

I am not great runner yet, but its imortant to keep up with paced run on full/ultra marathon course during those race🤔🤔 If person gets 8:30 warm up for few miles, try to keep running for under or close to 8:00 mile paces🫣 Just my guessing but prefer to reduce record, mix places to run for prepare marathon races as track field, hills, treadmill... If I need to know more, I'll appreciate to hear more

Foot landing bellow bending knee... which knee? Same foot or bellow bending knee of the opposite leg..?

Do everything in your possibility to not run naturally according to your morphology and spend your life trying something you are not made for. good luck :)

Nearly all the runners in the video have their arms crossing to the centre of their bodies. Which contradicts the audio

Easier said than dunne lol.

You want to be a good runner and break the record forget about all these videos and the techniques . all you need is loosing weight .be skinny and practise .run run run .you will be fast strong and good .im 50 years old .i run 5k in 19 minutes ❤️

why nobody is talking about huge difference of vo2max of elite runners with what mere mortals like us posses

0:16 oh this aged… like milk… RIP.

Elites get injured as much as recreational runners

All are age 25 or less...and already in practice

The clip of the runner at 4:47 doesn't fit in, that's quite bad form. Arms swinging across the body and massively overstriding. Also that person is sprinting, not running.

It would have been better if you actually show how to do that instead of just random people running

It's all about genetic

Have try to measure all this things when you’re running? 😂 The worse way to run properly is to think so much about running. Running is natural, we didn’t see any improvement in technique since… never. Is only a matter of practice, and practice, and practice: easy pace allows for feeling relaxed and good posture. Tempo runs allows you to maintain effort under control, and starting to lean balance when movement take more amplitude. And finally some little moments of over threshold paces allow you to feel power, still under posture control. We’re made for walk and run, thinking about it usually don’t improve the thing, is not like swimming. I think the problem of leaning forwards (breaking the hip alignment) is due to fatigue. Most people run too fast and not so often to allow themselves to run as natural as breathing. If you construct your basis solidly (basis are always the pace less than 70% MHR the whole run, I mean always under this 70% not an average: you must begin your session at 65% or less because cardiac drift), you will run with good posture. Tempo always below threshold effort, running so close to the threshold increase fatigue rapidly and disturbs posture and concentration. Many runners obtain a threshold value from tests and after they run exactly at this pace, but is much better to work 5% slower, or 10-15 sec/ km above threshold. Speed should be practiced just over threshold in endurance running: 10k pace or just 5 seconds/ km. Also I see many runners training sprints at 1500 or 800 pace without learning to run at 10k pace confidently. Make all these good trainings and posture, cadence and balance will soon arrive! 😎
