What Happens To Your Body When You Run A Marathon?

It’s easy to forget just how incredible our bodies are and what it really takes to run a marathon. Sarah and Mo have recently taken one on and have decided to look into the science behind what’s really going on both during and after a Marathon beyond what we see and maybe even feel!

Format doesn't really match the thumbnail and title. This is yet another generic marathon prep video (I get it, it's the season). I was hoping for some good science on what actually happens to your body in a marathon - like at the biochemical level, how much damage it does, how is your body changed by the event etc

My first attempt at a Full in 2 weeks in Melbourne. I’m running for my dad who passed away in February and always told me to dream the impossible.

Started running in April this year, signed up for a marathon next year September to keep the momentum going. Really nervous but I hope having so much time to prepare will make it a good experience! All these videos are super helpful and informative, thank you!

Ermmmm still unsure what happens to my body when I run a marathon?! Not your greatest video team! Very misleading !

Not brought up in great detail is what happens post marathon in the week (s) following. Cadiac fatigue and DOMS some post marathon issues runners need to deal with, the heart is a muscle and it could be damaged or fatigued after a marathon effort, so prioritizing enough rest before starting training again is important to prevent any cardiac related health issues.❤

The thumbnail and caption says something different from what's being shared in the video. We've heard a lot if this. Thought maybe some science was going to be explained as to what really happens to your body during a marathon 🏃
Thanks though.

I am pretty lucky because I can recover from a marathon in 1 to 2 weeks (slow runner advantage) but this year I was mentally drained and it took me about 7 weeks to get back into regular running.

The person who finished the marathon is not the same person who started the marathon.

Man wish I watched this a week ago. Ran my first marathon (well ran the first 20 miles and walked almost the whole last 6 miles), hit 5:53. Not great. Was not expecting to start shivering halfway through the run, and was not expecting exactly how much my upper back would start hurting.

Mo's hair game is ON POINT (no shade thrown on Sarah's barnet).

Im 37, havent ran distance since i was a senior in high school. April, i made a change and decided to start running again. Made a goal of 100 miles by the end of summer. It hit that goal by July. So i set my sites on the marathon. In the lead up to the marathon(Sunday) in Friday my dog got hit by a car and broke his leg. Im very thankful hes alive. But i got maybe 3 hours of sleep from Friday to Sunday morning. I ran my first ever marathon and FINISHED.

Is it normal to get super emotional after a run like that? My emotions are all over the place. Lot of happy tears, i guess.

[EelcoZomer]

Ran my second marathon yesterday. And ran under my lactate threshold the entire way. A massive difference and could drop the hammer the final 5k, did a pr! But a video about recovery would be good.

[julienl]

How about getting a slight cold after a marathon? After my second marathon I again am getting flu or cold like feelings.

[chinpoeykhoo]

Prefect video and timing for my 2nd full marathon next Sunday target Sub 4 while I'm undergoing tapering stage at this moment, best of luck to Jess attempt to break her first Sub 3 marathon in Berlin!

[ivartheboneless]

I never thought of per loading electrolytes that’s a great suggestion thank you

[graemetough]

Title and content not consistent...unusually poor for TRC

Could you do a video on what happens to your body when you run an ultra (100k or 100 miles).

[zeniktorres]

Wow! Your PB is 3:45! How in heck did you get to that!

[dustinhalfmann]

what happens to your body when you run a marathon?

[marcleong]

Yeah I am curious how long it takes to actually recover after a marathon. I actually heal pretty quick jokingly my gym friends call me Asian Wolverine cuz after I did my first half marathon I was fine the next day. I had a buddy scan done and the protein that heals muscles is higher in me than normal. I do have my first marathon attempt in 2 weeks. So yeah, I'd be curious to know what the average time is to heal
