I ran one… FOR SCIENCE!

So maybe we can't outrun cheetahs or antelope, but humans are uniquely adapted for long distance running. What does science have to say about marathon running? To find out, (and because I was feeling a little crazy) I decided to run one!
Here's what I discovered about the science of long distance running

For all of you who wonder why Pheidipides died (although he was a messenger , meaning that he was one of the official guys for jobs like that , so he was training regularly) : Around 2 weeks before the battle , he run from Athens to Sparta (246 km) in a day and a half (around 36 hours) , he asked Spartans for help , he slept a few hours and return back to Athens (and we can be sure that he the return trip Sparta-Athens in less than 2 days). Then he participated in the battle of Marathon , so he was fighting for an hour or 2 with full armor. Then (without getting rid of everything from his equipment) he run to Athens.

[@THERepublic1971]

He died because he ran to Sparta to ask for help, they denied his request because of a religious holiday, so he ran back. This totaled 280 miles. When Marathon won the battle against the Persians he then ran to Athens and died . He died because he ran over 300 miles in a matter of a few days not because he ran an easy 26.2 miles, which is not the distance. 26.2 became the distance in 1908 during the Olympics in London. You're a scientist not a historian.

[@JustAnotherRunner]

+Jon Scovell Mic drop....

[@phampants]

The modern distance of a marathon of 26.2 was set at the 1908 London Olympics because the finish line was not where the royal box was located. So they extended the race & place the finish line at the royal. Since then, the distance became 26.2 Prior to that the estimated distance between the Battle of Marathon to Athens is about 25 miles.

[@iamdihan]

Yeah that kind of annoyed me when he said the distance from Marathon to Athens was 26.2 miles. Channel about being smart and does not give factual information

[@greghouston2521]

It's too bad the extra 1.2 miles was added in 1908. Otherwise, 25 miles is about 40K, a half marathon would be about 20K. Then a 10K would be a 1/4 marathon. Plus people routinely die running marathons due to the large numbers involved. Hopefully the shorter distance would have a lower death rate!

[@gakaface]

Apart from the odd small mistakes, that was really enjoyable. And running a 3:39 marathon like that is an incredible performance.

Very nicely done. I really enjoyed how you went about making this video--the presentation and involvement is extremely admirable! Mankind was born to move--we are the current product of innumerable years of evolution. However, I feel that there is something greater that separates us from the common animal (although we are still animals ourselves): the ability to be self-aware and to think in terms of time. This gift and curse allows us to understand ourselves as individuals and as a collective to a much greater degree which opens up a universe of possibilities. I am going down a path that I will never reverse--I want to grow and become smarter, better, and stronger with each day. If you find these words of mine to be genuine, please bring me your own knowledge and life experiences so that we may both grow. That is all, no more no less.

Ray Cruick Yes, and an extra mile at the start so the royal children could see the start from Windsor Castle. 26 miles 385 years was adopted by the IAAF in 1921 as the official distance.

Jim P No, but I do have them inside each of my cells! Thanks, mitochondria! The 38 ATP figure is a theoretical maximum per glucose, of course. In reality we don't get near that efficiency

[@thevirtualjim]

It's Okay To Be Smart lol, yea I was being a bit snarky. In one of my courses, I talk about 38 vs 36 for theoretical maximums for prokaryotes vs. eukaryotes.

+It's Okay To Be Smart Glycolisis only last less or like a minute, the energy that you are using to run a marathon is B oxidation of lipids. it gives you 108ATP per Fatty Acid instead of 36ATP per glucose molecule, plus you only store little amounts of glycogen

[@MolecularAnimationsoftheCell]

+Jim P every species has a different average ratio of ATP per molecule, cows are one of the most efficient.

+It's Okay To Be Smart The mitochondria is the powerhouse of the cell.

I found this channel today and watched a hand full of videos so far, which i liked, but watching this one i have 2... complaints or so, that would be really easy to fix. 1. weight is not the same as force, so you can not say a force eight times our bodyweight and especially you can't tell me how much force it is by using pounds. With this we come to the more important issue: 2. Please use SI units... there is (not) really only one Nation, that uses the Imperial system and this is the world wide web, so you might consider adding SI units in text form or even do it the other way round. Pretty please? Pardon my imperfect english and DFTBA

[@ilovevicandgretta]

I think you're confusing weight with mass; weight actually is a force. When you step on a scale, it is measuring the amount of downward force you apply to it, which translates as weight.

[@XyntXII]

okay, maybe i got this wrong in the translation, but still: if it is a force, why is it not in Newton but in a unit for mass (or is a pound not about .5 kg (a bit more)) i am a little confused right now, but thank you, for showing me the way to a misconseption of mine. tomorrow i'll clear that up for me. I would appreciate it, if you'd help me a little.

[@r080d]

Force is mass multiply by acceleration. Weight is mass multiply by gravitational acceleration. kg*m/s^2= N lb*ft/s^2= is also force but different unit.

Great run! Congratulations!!

[@aleandrian]

Congrats for your marathon and your video!

[@MadJDMTurboBoost]

6:54 ur nipple is bleeding lol

[@dubidooba7930]

Chafing

[@superoxidedismutor]

skysi I only get it with micro perforated ones running more than 15k (lol 15k i'm ok, 10miles i'm not) ran a 50k with a plain cotton t-shirt, no problem

[@AnnoyingAsianWitch]

That's why you tape it.

[@Nick-jb4xi]

What Denuris said. Those micro perforated shirts feel like razor blades on the nips after 12 miles or so. Vaseline, tape or band-aids if you want to be safe.

[@christiana1137]

Tbh I don't know how people can run that much I'm tired after like 2 minutes

[@Savistohome]

A lot of people start with programmes such as Couch to 5k, then move from there. Will power, determination and a bucket of patience are key. :)

[@platinumpineapple9943]

u train and build up to it, i just hit a 16:52 5k after barely being able to run for 6 minutes this at the beginning of the season

[@Savistohome]

Holy cow, 16:42?! If this was 1897, you'd be close to the world record! :O

[@platinumpineapple9943]

Savisto Home 16:52 and yea theres been plenty of people on my team that have beaten 16;42

[@Savistohome]

Platinum Pineapple That makes my muscles hurt just thinking about it. :O You and your team have impressed this novice runner. ^_^

[@vijayvk4692]

Thanks for your information sir.

[@SpotGoes]

Great video. Love the mental game aspect.
