Let’s be trustworthy, most of us have questioned if it’s good for us proper about mile 25 when all the pieces hurts! And but…we do it once more as a result of one thing in us is aware of there’s good when DONE RIGHT.
Which is to say that you’ll have much less impacts from working a marathon if you happen to’ve executed a correct construct up, you’ve been power coaching and fueling.
A whole lot of what I’m about to share from the science may have some individuals pumping their fists and saying “see we instructed you working is dangerous for you.” However that’s not likely the take away right here and most are very non permanent results and don’t evaluate to the overwhelming well being advantages of lengthy distance working.
That being mentioned, we’re not claiming that marathon working is to your well being. If wholesome and longevity is the main focus, I don’t know that 26.2 is on the checklist.
What Occurs to Your Physique After a Marathon
Coach Laura Norris and I dove in to the analysis to bust sure myths, discover solutions and provide help to higher perceive why we push so laborious for submit marathon restoration time!
Right here I’ll summarize our key factors from the Tread Calmly podcast, however you need to hearken to the complete episode embedded beneath!
And most significantly, understand that this stuff are taking place unbiased of your tempo!! Operating sooner doesn’t meant it impacts the physique much less.
So let’s dive in first with what occurs to your physique after working and a marathon. Whereas a few of these can sound just a little scary, working a marathon isn’t dangerous to your well being (assuming you haven’t any underlying circumstances).
#1. You Shrink
That’s proper! Operating usually compresses your spinal discs and so any run over half-hour will trigger you to be a bit shorter, with the period of the marathon you’ll be able to end as much as 1/2 inch shorter!
Whereas there could also be disc compression that results in us being shorter, the research say there isn’t any actual long run degeneration taking place. And we all know that redhydrating plumps them again up an one other research confirmed working may very well assist cut back degeneration
Past your discs, there’s really some loss out of your foot collapsing downward by as much as 5mm. Once more brief time period and certain muscle fatigue.
#2 Discount in Lung Operate
A 2019 evaluate in Sport Drugs discovered that you’ve got as much as a 15 to 25% decline in perform in your lungs and in your diaphragm muscle mass as a result of fatigue of heavy respiratory for thus lengthy in a race. Once more, that recovers fairly shortly.
It simply means that’s why you’re feeling drained and out of breath, in all probability simply strolling round after a marathon.
However once more, goes to indicate that doing this race, working is a complete physique sport. We see it influence your bones and your muscle mass and all the pieces.
#3 Mind Fog or Heightened Feelings
The opposite factor that a lot of you could have in all probability skilled is perhaps you could have simply loads of feelings on the end. I imply, I cry at each end line! However you might also really feel like I can’t actually decide or I can’t assume to inform my household the place to fulfill me.
That’s mind glycogen that’s been depleted.
Your mind runs on carbohydrates. And even while you’re fueling your greatest, you’re in all probability not fairly hitting the precise quantity that your physique and your mind is utilizing since you would simply be taking in a lot.
#4 Swollen Ft
We regularly speak about needing to purchase bigger sneakers as runners and that is because of ft swelling with extra time on them. In reality, one research confirmed they develop 4 to 8mm which is why we’d like that longer shoe otherwise you would possibly want a large on race day.
But additionally, your ft will swell extra AFTER end the race.
Blood circulation is now not being diverted to muscle mass, so it might begin to rush again to different areas like your ft. Probably why these working restoration sandals feels so dang good.
#5 Systemic Irritation
Okay, you already know issues are infected…however what about your coronary heart?
The identical 2019 research, they discovered that troponin ranges had been elevated for up to 4 days after a marathon. Troponin is a biomarker that signifies acute harm to the coronary heart muscle mass.
What’s really actually vital about this research is the conclusion WAS NOT that marathons harm your coronary heart. It was extra a discover that if you happen to get bloodwork executed proper after a race you’ll have elevated ranges of this and different markers like C-Reactive protein, creatine kinase, lactate dehydronase (principally muscle, tendon, ligament harm).
It’s one other reminder that we don’t need to leap proper again in to coaching as a result of there are issues you’ll be able to’t see or really feel taking place.
We cowl much more within the present, however these are among the highlights that assist reply that so frequent query of what does working a marathon actually do to you??
And I hope, you’ll be able to see right here that the majority issues are very non permanent, however certainly are necessary and reinforce why resting is so essential!!
Is it true that you just want at some point of restoration for each mile raced?
That is an adage that each Laura and I heard early in our working careers. In some methods it is smart as a result of the longer the race, the extra restoration your physique wants.
However when you’ve been working for awhile taking 26 days off of working after a marathon may not being totally mandatory, relying in your targets. That being mentioned, the elites do it!! They typically take a month and even 2 off after their huge purpose marathon race of the 12 months.
Once more, all of those information factors remind us that restoration is a lot greater than you “simply feeling able to run”. The physique is doing loads of stuff behind the scenes that may really provide help to to comeback fitter, after taking the suitable period of time to get better.
Typically, we advocate 10-14 days of no working for just about everybody. Beneath you’ll discover further assets for a full submit marathon return plan.
What is going to reduce the influence of working a marathon?
As famous earlier, having executed the suitable coaching is a large issue. It doesn’t imply that being tremendous nicely skilled eliminates all the pieces, but it surely definitely helps.

When you fueled and hydrated nicely with pre and intra race carbs, you’ll be able to really assist to hurry up therapeutic.
