What Happens To Your Body When You Run 5k?

[@Jimthetyreman]

Yesterday, Sunday 4th of Feb, I did a 2 hour long run, I use time NOT distance when training. I had a 98% of zone 2!!! I LOVED every minute of it!!

[@soulsonicfarce]

This is almost exactly my experience from my long (25k) on the same day. I aimed to stay within my zone 2 heart rate as far as possible (92%), keeping a steady pace for 2 and a half hours. All goals achieved and loved every minute 😁

[@gazza2933]

Good work Jim!

[@drmayanksinha]

My zone 2 is walking 😭 No matter how slow i run my HR shoots up to 150

[@daeondreponder7496]

Then walk a marthon ​@@drmayanksinha

[@freelounge6001]

@@drmayanksinha Just run-walk-run-walk then, that's what has helped me get my heart rate down more consistently. When you hit 150bpm, walk until your heart rate settles back down into the zone 2 range, then run again until it hits 150. You'll see your heart rate ramp-up time start to stretch out longer and longer after a few sessions of this, so you'll be running more and more in zone 2 and low zone 3. Of course you'll want to mix this up with runs where you just sustain in a higher zone as long as you can, as that will deliver benefits as well.

My best runners high happened last year at Buffalo marathon. I had a good hydration/nutrition plan which was doing great.... until mile 18 and then the struggle bus was in full effect. I wasn't sure if my goal of sub 5hrs was going to happen, but then it happened "runners high" (about mile 24) all the pain went away, and I was able to push through the finish. I am also not ashamed to say as I crossed the finish line at 4hr 45 min. I was overcome with emotion and couldn't help but cry..... Best day ever and thanks in part to all of you and the great content you put out on the channel.

[@runningchannel]

Congratulations on Buffalo marathon! What an amazing achievement😁

[@drbikeshorts]

That’s a lot of big words to spit out during a 5k. Well done!

[@soulsonicfarce]

I got a mad week-long runners high after my first official half marathon, beating my 2 hour goal by 6 minutes and my PB in training by 8 minutes. The sense of achievement and well being it gave me was like nothing else I’ve experienced. I was 48 and I’d never been a runner until 8 months before the race

I did my first ever 5k last weekend. Ive been very sedentary, so im not sure about a runners high, however i did note that my constant anxiety has lifted and ive been more productive generally. Looking forward to running again this weekend

[@MrMisuma]

Not long I ago, I tested myself and ran 5K every day for 5 days. I was proud. Proud and curious enough to do 6K every day for 6 days. And I was even more proud. And I thought that was enough. But I just ran 7K every day for 7 days! I’m actually less proud of the physical side of it, but more proud of the willpower I found in myself 😊

[@CustardDonut]

@@CustardDonut Haha! No. I’m back at doing 6K for 6 days.

[@fastfiddler1625]

My biggest runner's high was my first half marathon. I had my earbuds, music, and audio books ready to go. I didn't use them once. I was so caught up with omg I'm going this! As well as keeping tabs on my body and focusing so I could run as fast as I could without burning out. I was worried I'd get bored running for 2 hours 5 minutes. I did not get bored.

[@flaviuskern225]

Ran 6.3 miles yesterday, my heart rate during my first 3 was 150’s; continuing same pace, my heart rate dropped to 120’s during my last 3 miles…didn’t consciously change anything, but I do notice my breathing becomes effortless.

[@Stevemulka]

My Sunday long run got delayed and as a result I finished the second half of the run as the sun was setting. I crested the hill to be greeted by a lovely warm yellow glow, this together with the amazing countryside and (insert whatever you said it was that causes the high) made me feel amazing in fact very emotional. I was ‘whoop, whooping’ all the way home :-)

[@GoonGucci]

I just started running 5ks I usually finish at 50 minutes , but I just started running not much of a runner. I also weigh 200 pounds and I’m 6’3 I can’t even imagine running anything under 25 minutes 🤯

[@nikolajjansdaldreijer2445]

FIRST! Oh that felt great. This has been a dream of mine for the last 72 years! I would like to thank my parents who have always believed in me

[@rjsouthworth5246]

The runner's high I best remember is when I was running my first half marathon (virtually as it was during lockdown). I was about halfway through and I just felt like I could keep going forever - Phil Collins's "Take Me Home" was playing on my headphones so I always associate that song with the feeling now.

[@DarenC]

The muscles in my legs do most of the legwork. Got it! 😂

[@rachaelbullmore48]

Does anyone else get the post-run chills? I usually feel absolutely frozen to the core about an hour or two after a run - whether 5km or 15km or anywhere in between. The longer my run the longer it takes to get rid of the chills. I usually have to have a piping hot bath/shower, drink coffee and dive under a duvet to warm up again. You can almost set your clock to it if I have attended parkrun

[@theghostofpcs2391]

Yes, I do. I'll be fine at first, but once I'm cold, it's almost impossible to get warm again.

[@paulhanson1600]

Only had this doing a marathon. But I also try not to run much in cold weather in Jan/Feb!!!

[@runningchannel]

I've always disliked running, but something clicked the past week and I feel the desire to start running.

My first runners high happened some months later when I first started running. It was like a tense focus, things looked so clear, like if my body and mind were working together. I notice picking up my speed and maintaining it more than usual and there was like a cool tingling feeling through in my body. I've been running for 6 years now.

[@mickwful]

After most runs, sit down have a brew. That was easy look forward to the next one. Except a Marathon after the first few hours have worn off I felt lost and down. I think this is because it had absorbed so much of my thoughts and life that I now had to find a new purpose.

👏 I ran about 4x per week clocking 30km mileage weekly and I will run till my knees can’t take no more. It’s the best destressing cardio workout

[@cannuckchick7522]

The good news is that runners don’t have a higher rate of knee replacement because we tend to not carry the excess weight that so stresses knees as we age.

Maybe this is not a runner high but I just started running in a treadmill recently, it's too hot outside, and could only do short intervals of 2 minutes, 1 minute and a half and one minute and lots if walking between. Once i was done i felt something like euphoria and the world was snapped into focus like 4k and I felt great for the rest of the day and felt like i could breathe better, not sure it was runners high but i felt great

If you're experiencing extreme dizziness it's definitely worth talking to a health professional. Headaches after running are often down to dehydration

Not extreme thankfully. Just a few seconds and fixed by a cooldown. I'll definitely try more fluids though thanks🙂

[@gayleewoo]

Very late reply but...when you're running all your blood is getting pumped hard around your body, if you come to a sudden stop then the blood is still pumping hard and that's why you feel dizzy. Walking after gives your body time to bring your heart rate down and the blood stops pumping so hard, that's why you feel better when you walk, and why the cool down is so important.

[@listrahtes]

Dont like his running form. Too much vertical movement and excentric bend in the knee during initial contact. He looses a lot of energy like that and strains his joints unnecessary. A lack of drilling the mechanics of landing and how the glutes and hamstrings pull us through. Also his upper body despite being very muscular has a lack of lower body tension while running. A focus on b skip could help among other things. Its not a big thing as he doesnt advertise this video as running form but for a 5k tempo I wouldnt show this form on a video. . Also there is not the one "runners high" Endorphins have not been disproven: With amateurs its often when they reach the abiltity to run without funcional overload which can take quite some time even on slow runs for all body systems. They then think that the body is drugging them as they feel so good but its just a well working machine. Parts of runners high is mental strenght, endorphins, endocanabinoids, defocused attention (very important to it) and for people always thinking about it attention bias.
