The fact that it's so cold also helps. The greatest advantage of humans over other animals when it comes to long distance running is the fact that we can sweat to dissipate heat. There is a traditional race ran every year somewhere (I can't remember the location) where humans compete against horses. Typically horses win on colder days, whereas in years that the race was held on a hot day, humans had the edge.

[@wilfinley]

I'm not sure why the video fails to mention climate, but that is the singular reason why Huskies can outrun humans. Available energy isn't the major factor that limits animals from running long distances - it's the inability to regulate their body temperature that does. Our ability to sweat across our large hairless surface area makes humans the most versatile long distance runners on the planet. Try and make a Husky run a few miles in 80 degree temperatures and see how that works out. They're poorly suited to running anywhere but cold climates.

[@gageanderson7612]

Wil Finley its not the sole reason though. For instance, a pig can also sweat and is hairless, yet the still can't outrun us because the use more energy than they can restore.

[@wilfinley]

Masonic Bonsai - only domestic pigs loose their hair and all pigs have very few sweat glands. As far as I am aware humans are the only extant species that is covered from head to toe in sweat glands. That's why we rock so hard at temperature regulation. Chasing mammals on the plains until they collapsed from exhaustion was probably one of our ancestor's more successful hunting strategies in the distant past.

[@humanperson2775]

But dogs have four legs so it's easier for them to travel rough terrain... ;( My little dog can outrun me and out-stamina me...

[@medalf]

Four legs is actually pretty bad for running long distances. Ostriches are the best runners in terms of energy conservation since their legs are basically pogo sticks. They can also run for more than an hour at top speed of 70 kmph. But even them could be outrun if the chase lasted two month like for exemple the Trans Europe Foot Race (64 days of running an average of 80 km per day). I'm not sure who would win in a yearly span between a sled dog in cold weather and a highly trained ultra runner but that would be an interesting race.

[@leonhardfrommhold8463]

medalf the sled dog would just win. The fact that he can run on glycogen all the time (or doesn't need it) just makes him so much better. A very gig advantage of humans is that we have two legs instead of 4 ( still better) and , most importantly, can sweat. But sweat isn't needed in cold climates and in days long race glycogen just outclasses 2 legs

[@arcticnerd5994]

I grew up working with my neighbors sled dog team. She used to race in the Yukon Quest and it was amazing how far those dogs could go in a day. I would get tired running the sled before the dogs would.

Dogs can only run long distances in cold weather

[@Cythil]

considering when we use the term evolution we generally refer to natural selection then the original poster statement is wrong. This was achieved by artificial selection not natural one. Also fitness is a bit of a tricky concept. There dogs are extremely good at long distance running. Which is useful to be sure for survival. But the extreme ability to run these distance can not be achieve in nature as humans need to provide the fat and protean for the dogs to continue to run. They would not be able to acquire the amount needed on there own in nature. So in the end they would not really have that much advantage compared to wolves. It may actually be a disadvantage in nature as the dogs could maybe run out of there fuel reserves without knowing it. While regular wolves would have that glucose fatigue kick in before they overextend there fuel supplies. (If we use the wider definition of the term evolution then it correct. As Evolution in a more general sense just means change.)

@@steirqwe7956 Ok but if you ran the race in conditions where a dog team can't run efficiently a camel would probably win, Also, there is very few animals in the world that can take part in a 1,000 mile race. Being domesticated is a prerequisite. A wildebeest might do it faster, but a there is no way to test how fast a wildebeest can travel 10k because it's a wild animal. So you are really only competing vs domesticated animals like dogs and horses and humans come 2nd when they get to set the race distance and environment that suit them best. So it is a very misleading claim imo.

[@guitarstaraces746]

The average dog is faster and can run a lot further than the average human, I'm fairly certain of that

[@olenickel6013]

@Chris Russell Huskies can adapt to warmer climates. They are Siberian dogs, used to continental climates that get drastic climatic changes, including short, hot summers. And while Huskies are working dogs and need exercise, not only physical, but mental, they are also very social animals (the Chukchi tribe that originally bred them had the dogs watch their children) and make great family dogs if you can provide enough exercise, because of their naturally friendly and patient demeanor. So no, having a Husky as a family dog in a warmer climate isn't animal cruelty.

I don't know. While sled dogs do have incredible endurance and seemingly do not tire in their work, to my knowledge, they can and do get tired. Some are even said to collapse or even die from exhaustion.

[@andy4an]

yeah, of course they get tired. :) I was riding with dogs that had been running much of the day from 8am to 1am, and in the last hour, we took like 3 breaks to rest the dogs. This video could still be mostly true as far as I know though.

[@coltonsmith5997]

They do get tired yes, but they take breaks. As someone who follows sled dog races(I have a couple friends who run in them) one thing that isn’t publicized much is the amount of breaks they take. There’s a pit stop every 25-50 miles on the longer races where the dogs can stop and take a break. For up to twelve hours. And yes sometimes some dogs are just too weak to keep going, I even had it happen to a friend of mine, but then all they do is put the tired pup in their sled until the next checkpoint and then send it home and call in a new one. And lastly, it’s hard to describe to someone who hasn’t ridden on a dog sled how much the dogs enjoy running. They were literally bread for it and it’s the greatest thing to them.

[@Mrraerae]

@@coltonsmith5997 yea they can't wait to run, and when you go visit some place where they do dog sled tours you can see all the dogs that are waiting and crying and howling and jealous trying to tell people to let them run.

I have a theory about the glycogen conservation. It's possible that after getting the fat and protein started, they re-route a small amount of it through a valve to do the job that the glycogen normally does in all other mammals. Using this theory, it can also help identify why recent racers do better. Their metabolisms just takes time to shut the valve, and having a pre-running gas is faster than taking time to switch it on. It's a similar concept as getaway drivers during robberies or carpooling. it simply saves time to hop in and go rather than taking tie to put in the keys, change gear, and start driving after.

The cold weather actually helps them to not overheat for with that fur they have, they could overheat if they would run full out if it is "just" minus 10 degrees

I highly doubt humans have more stamina than ANY other land mammal other than sled dogs. What about wolves? They "jog" for miles and miles everyday and almost never slow their pace.

[@caimansaurus5564]

Humans in peak fitness condition, or the way most adult hunter-gatherer humans (especially in flatland areas) are. Most modern, sedentary humans couldn't hold a candle to a poodle.

[@Kyonarai]

Not many people can hold a candle to a poodle anyways, because people forget that standard poodles were bred to be hunting dogs and are actually very strong and agile if conditioned properly, lol. The reason why huskies would be better distance runners than wolves is because of our artificial selection for the fastest/longest runners. We've bred them so that not only are they perfectly designed for running, but they LOVE to run. A racing line husky relishes running more than any other activity, so much that if you put them on a dog powered treadmill, they will run themselves into exhaustion if the humans don't regulate their run time. Sadly, many pet line and show line huskies have had these traits dimmed down or bred out entirely to make them better pets, because racing line huskies are so manic and full of energy that most people can't handle them. If not allowed to run, they get anxious, neurotic, and destructive, and so make poor house dogs. This is why, when organizations like PETA and others, which are super anti dog sport(despite the fact that dogs LOVE doing their sports) shut down sled races and rides, many of these dogs are left homeless, and end up being put to sleep in absence of the job they were born to do and love.

[@Burn_Angel]

Kyoranai So, you're saying that, because PETA is against animal abuse, they led lots of dogs to "sleep"? Yeah, that's to be expected from PETA.

[@Kyonarai]

Yep. They euthanize 98% of the animals they take in, because to them it's better to be dead than someone's beloved pet.

Actually, humans can do the same thing if they walk. It is in fact the best (realistically the only) way of loosing fat. If your goal is to loose fat, don't do 1h of HIIT every morning and every evening, you're just using up the sugar stored in your blood, liver and pancreas. Those reserves need to be completely depleted before you start using up fat tissues (Usually after around 90 min of intense exercise). Want to know the "one secret that will make you loose fat permanently" ? Walk. When you perform really low intensity exercise, your body taps into your fat tissues to get energy rather than the sugar storage. I think this is because it wants to maintain sugar in case you need to run (if a predator shows up and you need to run away), but would have to check. Point is, low intensity exercise makes you loose fat. Want to loose fat ? Forget 1h high intensity Spinning class in hot tents, you're just depleting sugar reserves and sweating water, go for a walk ! Don't walk too fast, remember: low intensity !

[@brandon9089]

well while i agree that humans are particularly great distance runners, it’s not very fair that we compare our absolute best versus a random animal. for example many people say we’re better than horses at the marathon because eli kipchoge can run it faster than the average horse. but what about the BEST distance horse, given a lifetime of distance training, good diet, and top facilities. i’m not really sure who would win then...

I had a husky growing up as a kid and a couple times she ran out the back door and escaped. We were probably like 10 or 12 years old but we just chased her around the neighborhood all afternoon until she slowed down or laid down and we would eventually catch her. Huskies will get overheated eventually, at least mine did and the ones my aunt had did (she worked with race dogs). Human children on the other hand seem to have an infinitely deep well of energy along with a strong need to run circles around the kitchen table. (Granted, climate seems to make a big difference, this was in U.S. during spring/summer.)

[@johnfadds6089]

I used to run with my cousin's golden retriever during summer. The dog would have explosive energy at the start, running all over the place around me. After about 15 km it would start falling behind panting heavily, not running but trotting at a slow pace, so I would stop and let him recover. Wouldn't want anything bad happen to him. This was an average dog, not the best nutrition or fitness level but I have never seen him tired like that. He could probably run all day and more in cooler weather. Dogs maybe don't get tired, but they do overheat.
