Anecdote for any runners reading this: I'm a 75 year old runner. (Some young runners might say I run at a jogger's pace, I just tell them to keep off my lawn.) A couple decades ago, I stopped running on concrete or asphalt, and took up trail running, i.e. running on (mostly) dirt. It feels way easier than running on asphalt, much less on concrete. If you're skeptical that running on concrete or asphalt feels harder,…

Why not take up cycling?

I don't like the risk factor. I was a serious cyclist for a decade or so, and went tens of thousands of kilometers over all kinds of terrain at all hours of the day. My take away eventually was that I'd get hit by a car eventually (again), and I don't know how severe it would be. I only cycle with friends leisurely now rather than as a frequent form of exercise.

I live in a city where it's challenging to reach safe riding territory in a reasonable time frame. If I was rural and had access to trail riding (gravel, mountain), I think I'd be all over that.

This sounds interesting. Would you be able to share more information about this style of running? I'm having a hard time imagining how this plays out in real life.

Running barefoot forces you to improve your technique in line with this description. [0] There's also a sizeable market of "barefoot shoes" that's between being barefoot and the regular running shoes, with the manufacturers trying to convince us buying such shoes is the solution. The gait issue become more obvious (and painful) in barefoot shoes, but you can adjust your technique in mass-market running shoes as well.…

I first found out about this back when Chris McDougall's "Born to Run" book came out. For anyone that does not know, he follows an Indian tribe in Mexico known for their running prowess, using non-traditional sandles to run in instead of the heavily padded sneakers most of us wear.

I switched briefly around that time to running in vibram five fingers, which trained me how to change my stride and stop heel striking. I no longer wear VFFs but do tend to favor lightweight, minimal heel-drop sneakers, and I still don't heel strike.

I switched to trail and found I stopped getting injuries related to lateral stabilization of my hips and legs. I've come to think it's because the trails challenge those stabilizers sufficiently so they get trained properly rather than... I don't know, repeatedly being irritated by running too straight for long periods of time? I'm not a kinesiologist so I have no idea what the real difference is, but I do know I get…

Interesting, as if a narrow kind of stimulus is detrimental to biomechanics, while diverse terrain, even if more challenging, keeps each angle of motion hit below the limit

It's complicated, rotator cuff tear combined with a bunch of rib, shoulder and neck injuries. I never properly healed them, just rest, career in tennis ended after trying to rest and heal 3 times over 8 years. YouTube and Physical Therapy combined with the UC David protocol has brought back more strength and mobility than I've ever had. My main issue I had before was I kept pushing my injury too hard without proper r…

Thank you! I searched for "UC Davis protocol for shoulder" and found Dr. Keith Baars at UC Davis and his research on tendons: [Tim Ferriss podcast re Baars' work at https://tim.blog/2025/02/27/dr-keith-baar-transcript/ and "dastratman" has produced an excellent summary of Baars' and Ferriss' discussions: https://hackmd.io/@dastratman/rygQhSmhke ] I searched your old HN posts and found that you've explained this befor…

Yep you found it, sorry I got a bit mixed up with the threads here.

You're not wrong, but most of us don't live near a good dirt running trail so we have to drive to reach the trail head. When we have to squeeze in a run on workdays it becomes a choice between running on the street versus not running at all. Mud is also a problem for trail running in areas that get much rain.

I recommend artificial turf soccer fields. They're padded! They're flat. They're good for watching games, or people watching too. And you can pretend to be a winger or striker, constantly measuring the angle and distance to the far right corner, because who doesn't want to be like the GOAT?

Why not take up cycling?

cycling looks like less whole body and more targeted exercise.

Maybe, maybe not. It would depend on a variety of factors including the activities you do, your age, etc. Maybe athletes need more collagen compared to people who don’t exercise, etc, etc. Also complete protein sources are definitely not easy to get. Good luck if you have dietary constraints.

Notably, whey is a complete protein source and very easy to get, while collagen is a crappy source.

I just wish whey was as easy to get unflavored. Let me handle the flavoring, you provide the protein.

Yes, I'm aware you can buy unflavored whey protein, but it's more expensive and you have to order it online. I can get a huge tub of "Delicious quadruple chocolate delight" BS from Costco for comparative pennies.

>"Why not take up cycling?" I was a cycling maniac for some time. It fucks one up (knees, back, elbows) anyways. After 10 years of that I cut it down to occasional pleasure rides. Luckily all my pains had stopped after a couple of years.

isn't jogging more impactful to the knees than cycling? I've seen this over and over.

> isn't jogging more impactful to the knees than cycling? I've seen this over and over.

my brief reading of studies shows there is no proven negative impact on knees from running. Some studies suggest there is positive impact: https://pmc.ncbi.nlm.nih.gov/articles/PMC11320545/

I can speculate that running is very natural to human, and body evolved for running through the evolution, and cycling is not natural movement.

You need to eat a ton of quinoa. Only the most dedicated vegan bodybuilder will eat that much quinoa. No thanks. Also, only animal sources contain hydroxyproline amino acid in significant amounts, which you pretty much only get from collagen sources. So while quinoa and other like even whey might advertise themselves as complete protein sources, no, they do not contain all the amino acids humans can use in significan…

Hydroxyproline isn't essential though, humans can produce their need from collagen, which they also produce as well as most other animals. > You need to eat a ton of quinoa Most don't: at 4.4% protein, a 65kg man like me needs 1.5kg of cooked quinoa per day and it's not a big deal: - You'll digest it like a king: quinoa is full of soluble and insoluble fibers and you won't feel puffy for eating too much. Easy in, eas…

There are plenty of studies showing that collagen supplementation helps athletes. Which means there are cases where the body doesn’t produce enough collagen for itself. And as you age, your body produces less collagen. Reasons enough to supplement with collagen.

I am 41 years old and have had hip osteoarthritis since I was 36. I am not supposed to do a hip replacement at such a young age, they prefer older people with weaker muscles to do less damage to an artificial joint.

A cure like this would be a godsend for me.
