@RatOrthodox As in ghastly?

I went on the slutstack podcast and revealed myself as “scary man”. Link in replies.

@tim_roozendaal Damn that average hr! Congrats!!

Conditions turned sour during the day. A lot of wind (5-6 Bft) and slight rain. Let the idea of sub 37 go and just attempt a pb (38:15). My mate, and pacemaker (35 10k runner), said we will just go out at 3'40/km and see where we land. He did a stellar job, keeping a steady pace even with the gusts of wind and kept me out of the wind nicely. Managed to smash that 37 even with horrible conditions with a chip time of 36:52 😱 More later. For now, very very very happy with this performance 🚀🚀

@tim_roozendaal Good luck, trust the process!

I'm racing a 10K on Friday and that means it's taper week. I hate them. The lack of exercise makes my mind go crazy. I'm constantly doubting myself; have I done too much or too little? Less focus and feeling restless overall. A big part of why I train so much is to keep my head in check, which doesn't help during taper week. That said, I'm looking forward to the race and picking up training afterwards. Nervous and excited. Goal is sub 37. Training shows I'm in a good spot but it has to come together on race day.

@chintya_qu @LeadworkSW i believe this is you but you are not credited.

This roof can last 100 years.... But everyone wants to steal it

@__el__toro__ Nice! I have been looking for an excuse to use them in a design for years but have not found it yet! Is lubrication normally handled with thick anti seize grease?

@90KZR No, just the external portion. I know all about harmonic drives. Worked with them for years.

I would love to see what these parts end up on. So many jobs you just have no idea, though.

@greef_kris Ja, maar wel thuis, op een zonnige zondagmiddag.

3,60€ voor dik 100 km ! Wie doet beter ?

@zanehengsperger @ahmedshubber25 I would guess something like SAAB's Strenx 1100

@ahmedshubber25 what steel grade?

The cab structure requires special steel alloys to meet iso rollover cab equipments and visibility requirements. The steel’s lead time is 12 weeks & needs to be ordered in bulk. Oh & this steel grade is only made & refined in Sweden 😉

@LaetitiaOuillet Heerlijk geschreven Laetitia, dank voor het delen!

@stevemagness @ChrisMasterjohn Steve, for an amateur athlete, what resource would you advise to get a rough overview?

@ChrisMasterjohn For every field, we should have a history of it required in grad school. I can’t tell you how much exercise science would benefit from a history of training. Same with many other fields.

The ability of science to go absolutely nowhere in 75 years is truly incredible. IG Spiesman showed in 1941 that vitamins A and D prevent colds when given together and do absolutely nothing to prevent colds when given alone. So what are we doing in 2025? Aggregating trial after trial showing vitamin D doesn’t prevent colds when given alone. People who make themselves slaves to the evidence base and subjugate themselves to the biases of the researchers who created that evidence base will point out that Spiesman’s trial was not as statistically robust as a modern trial and will argue we should ignore it and focus on modern meta-analyses. The critique is true. But Spiesman was not operating in a vacuum with his own random hypothesis. He was investigating why trial after trial had shown that cod liver oil, which has a balance of A and D, prevents colds, but A-rich D-poor halibut liver oil does not. This was in the midst of a massive campaign to optimize immunity against measles, mumps, chicken pox, and rubella by importing millions of pounds of cod liver oil per year while trying to make the American industrial work force solid as rock by preventing people from calling out sick with colds. The fact is that most science is not good because scientists pay too little attention to the histories of their own fields, work on incremental knowledge instead of big ideas, and chase grant money instead of trying to do the necessary public service of focusing on the most important things to know on the frontiers of what we have already discovered. Science marches ever forward, into an abyss of meaninglessness. If you want to not get sick, do what the Northern European peasants did for hundreds of years before clinical trials were invented and take some cod liver oil.

@LeadworkSW Fantastic work, thanks for sharing.

Let’s get to the point

@divya_venn @noampomsky Hehe yes that is nice. It is also quite famous, there is even jacket called 'type two fun': outdoorgearlab.com/reviews/clothi… But I always miss type four fun: not fun at all. Like walking in the rain for a day at cool temperatures without it getting an emergency. ^^

radical fun by @noampomsky is a delight but i especially loved this

@tim_roozendaal Well done Tim! That is a few minutes faster than my first 55 k on the shoes you advised me! I had no problems at al afterwards, however needed a week to get into training. Like somebody told me en route: you have a new problem. Now you know you can do it!

Wasn't lying when I said big day of running on Sunday. Shortest day ultra! Started at sunrise, finished at sunset. Marathon PR, 50K PR, 55K PR (all first time lol) Vomero Plus was excellent for the job. Still surprisingly bouncy at 50k. Now I'm very broken and very tired. More later 🫡

@RatOrthodox Damn are you now quoting Aleksandr Solzjenitsyn?

The line between chill bro and busybody runs through the heart of every poaster

@spoon369 @historyinmemes Most likely a splined shaft. It is the standard for a lot of power dense axle connections (motors, gears ect.) jerpbakbayless.com/what-is-spline…

@historyinmemes How does the driveshaft connection allow the sliding out?

A rare example where an engineer thought about the mechanic. (1950s)

@tim_roozendaal Sounds like the healthy choice, congratulations!

10k Time Trial DNF 🥴 I had a bib for a local race next Sunday but due to circumstance I couldn't make it. So I decided to run a 10k time trial to see where I am at right now. Didn't go to plan unfortunately. I think I over estimated my fitness and decided to go for sub 37 or bust. It is a pretty windy day today, 4 bft, which didn't help. First 3 km were into a headwind, and pace felt rough. I decided to hang back a bit and decided to push a little harder into the tail wind. But after 5k, the pace already started to slip. I came through in 18:44 and the 6th k was already in 3:50, 9 s off the pace. I've been dealing with a small niggle in my right knee for the last few days and decided to pull the plug at 6.3 to not spend another ~16 min in the red and risk further pain for a marginally PB, if I could ran a PB at all. Fitness is still pretty decent but it just didn't click today. Heartrate was pretty high in the beginning and my mental wasn't totally in the right place. I can spiral really easily, if my mental isn't really at the right place and then the first few k already feel heavy. It's definitely part of what happend today. Stopping was 50% quitting, 50% logical decision. This time trial concludes my norwegian singles approach, which worked wonders for my over fitness, but didn't really gave me the sharpness for racing. Will be back to the drawing board, and focus on races in 2026.

@stevemagness Steve, I'm a self coached amateur runner. You really succeed in cutting through the noise and help me filter on what does matter for me. The daily posts are nice nudges and the YT channel is a great resource to look up stuff! Also loved hard things, thanks for being here!!

I started this page for a simple reason: to cut through the noise. We are inundated with hacks, shortcuts, and superficial advice that simply doesn't work. My goal was to provide insight to help people live and perform better based on evidence, not hype. I wanted to create a positive, informative corner of the internet. No flash, no glam, just the stuff that actually helps. In an attention economy that pushes us to short and flashy, thanks for engaging with depth.

@jonhagedornmd Nice, working on your (perceived) weakness is always good! However, I would not take a Garmin metric as a goal because you might be tempted to play their (always limited) system. Instead, log your time on a nearby hill and test against that benchmark!

Main off season goal is to get this score above 80. VO2max has dropped post-marathon, but hills are my absolute weakness. On a mission to make my legs bulletproof. Heavy weights, more vert, more hill strides. 😤

@AshRuns100s Hi Ash, your writing put me to tears, thanks for sharing. I hope you have many more miles ahead of you. Congratulations for dropping out when you got what you needed.

I gave God my beat up kidneys & said "take running forever" He just laughed, handed me a bib, and said SEE YOU AT PINHOTI. First blog post in several years.. spoiler alert, I'm still a broken spiritual emo. Check it out: ashruns100s.com/2025/11/21/laz…

@JohnGoldman This article is useful: you need to be able to blow some air through the fabric. turigrinos.com/2019/03/11/bre… There is no reason a cheaper jacket from a running store would not be able to do this, go there and check. Don't have recommendations because I'm a jacket snob.

@JohnGoldman The trick is you do not want it to be waterproof, just somewhat windproof. Amount of breathability is shown in 'CFM'. Options from outdoor brands I like: Black Diamond Alpine Start Patagonia Houdini Air Mountain Hardware Kor Airshell All pricy.

Runner and outdoor friends - Is there a wind breaker / rain coat that won’t make me feel like a wrestler trying to cut weight? Everything I’ve tried so far has me roasting in a personal steam room as I run. Humidity like the rain forest. What breathes the best?
