@kr I heard you run marathons. Any thoughts on this?
So what is the optimal speed for least energy expenditure? And at which point do you start to run as fast as you can to achieve your fastest time?
Is it just a feeling you get at some point? Like you just know "this is my optimal speed"?
Do you try to optimize for speed in marathons? Or just that you could run as long as possible?
well i haven’t run a full marathon yet (i used to run track/xc in college), but typically the strategy used in all distance races is to be as close as possible to an “even split” for a fast time.
in other words, if you’re trying to run a 5km in 30 mins, the ideal scenario would be a constant 6 min/km pace with minimal variations (even though the first couple km will feel relatively easy).
I've been running 5k's pretty consistently, and posting my runs on nostr (#runstr). My last time was 26:28. Ran a half marathon a few years ago, like @kr said, aiming for good splits is the way.
Oh, interesting, I never heard of splits in the context of running before. But I used to check my time after I passed specific checkpoints to see if I was still "in time" or slower / faster than usually.
Guess I already did something similar, but just didn't think that I should try to keep the same pace. Hilly terrain would make this harder, but where I am now, my routes are quite flat.
But this means trying to give it all at the end is not a thing to squeeze out the last few seconds out of the time?
edit: Oh, I see. That's roughly what negative splits are about, haha
in a perfect world, you’ll be so tired in your last km that pushing to “squeeze out the last few seconds” will actually just maintain your pace.
if you find yourself running your last km way faster than all your others, it’s a sign you probably could have run a better time with a slightly faster pace from the start.
That's my watch... simple and effective. They say that it's also the al-qaeda's favorite. Could be because it's cheap? Precise? Both? dunno
A true bitcoiner watch. I think I bought it 5+ years ago for 10€.
But that was before my bitcoin time
I also heard that Al-Qaida part, haha
One reason why I posted a picture of the watch: to see if anyone knows this story
now we're ALL-qaeda hohoho ta-da!

ouh wow, i never seen his nym like that
my nym like WHAT
oh god, birdeye. I see it. fk maybe i am the fbi
hiding in plain sight :)
like a bird eye watching over us 👀
just noticed i never changed the battery of that watch. not sure how long such batteries usually last, but is this the nokia of wrist watches?

What did you notice? I cannot confirm or deny this.
Also, maybe you're sending rare sats to people 👀

I used to have one too
but then it blew up? haha
Battery ran out.
ah, oh. just thought about the battery too here

Well done. Re running - it’s a fascinating topic. I am a lapsed ultramarathoner and can talk for days about this stuff.
I can recommend the book ‘Born to Run’ by Chris McDougall.

ᕦ(ò_óˇ)Day 5 of exercising everyday before the saloon openshttps://imgprxy.stacker.news/tghN45w_u5-QvDsGT-bRzKOZb5bYteaVLvOu2FcvbBU/rs:fit:600:500:0/g:no/aHR0cHM6Ly9pLnBvc3RpbWcuY2MvM1IzTnZkN2cvc2lnbmFsLTIwMjMtMDktMjAtMTIzMjA0LmpwZw
Oh, oh, I got late with posting this. Got too distracted with notifications and the Pay It Forward Initiative and then some more notifications.
I went for a run today. It took me 31:37 to run roughly 5km.
In German, we actually call it "joggen" not "rennen". I looked up if there is a better translation than "run" (since you don't really run if you try to "run" a long distance or for a long period of time). There is also "to jog" in English. But it feels like this is not used much? Is this more like a trap where you can notice if people use "to jog" that English is not their mother tongue?
Anyway. When I run, I don't try to run for a specific period of time. I try to run a specific route (with a specific distance) with checkpoints in mind.
I do this because I think it makes it easier to "not cheat" by just running very slowly. Anyone can "run" 30min+ if you just walk. Running a specific distance is therefore imo a good benchmark. This way, you can also make a competition out of this by measuring your time.
This always brings me to this question: What is the fastest way to travel a specific distance, therefore optimizing for least time? And what is the most efficient way to travel a specific distance; optimizing for least energy expended?
For example, if we keep the distance fixed, we can expend energy to travel the same distance in less time.
But when we start to target long enough distances (for example, 10km), it becomes obvious that we can't expend maximum energy all the time since we will get too exhausted. And then we will probably be a lot slower since we still have to travel a long distance even after all our energy is already depleted.
So what is the optimal speed for least energy expenditure? And at which point do you start to run as fast as you can to achieve your fastest time?
