Walking and Eating
The Gentle Reader who is a faithful C-Blog devotee knows by now of my antipathy for running for fitness and my love of walking for fitness. One of the things I neglected to cover in my walking vs. running posts was the issue of eating. Walking and eating is way easier than running and eating. I must warn you that I am going into a zone that is graphic and TMI. You've been warned.
Running is a stupid activity that burns a lot of calories. This is mostly glycogen from your bloodstream and muscles instead of fat from your gut and butt. The body needs that quick energy to maintain the speed needed for running. When you run out of this glycogen, you hit the wall or bonk. To counteract this, runners drink sports drinks, slurp gels, and eat energy bars. They can't eat real food because the combination of real food in the gut with the up-and-down pounding produces a condition known as "runner's trots." Everyone else knows this as diarrhea.
Diarrhea is a constant at road races. There are even infamous tales of runners who have soiled themselves completely in a race. I'm not going to share the pictures, but you can Google them up if you don't believe me. There is also a Wikipedia article on the subject where you will find the context of the opening quotation of this blog post.
Runners will blame the trots on "trigger foods" before a run or race. Everyone thinks immediately of Taco Bell which is a trigger food for every member of the human race except me. That is one of the upsides of a plant based diet, but that is a topic for another post. With runners, all solid food is a trigger food for them. This is because the trigger is the running and not so much what they ate.
If you are a runner, the choice is stark. You can risk bonking, or you can risk explosive diarrhea. Sometimes, you get both. The undeniable fact is that the human digestive tract hates running. This is a big reason to give up running and become a fitness walker.
Walkers don't have these issues. Walkers can eat a Thanksgiving level dinner and go walking immediately after. The walking actually aids in digestion. Many people go for a short walk after meals for this reason. Food is never an issue for a walker unless it is Taco Bell. Walkers also don't waste money on expensive sports drinks and energy gels. I like a granola bar or a sandwich before my walks when I think I need some food.
I couldn't do this sort of thing when I would run for fitness in my younger days. I have had some close calls with runner's trots. I will spare the Gentle Reader the worst details but trying to manage running and nutrition with other aspects of a busy schedule was a nightmare. Why did I ever waste time with running? That was really dumb.
I have had to go to the loo in the middle of a walk, but it was never catastrophic. I have never soiled myself on a walk. I can't imagine how a runner wants a medal so bad that they would expose themselves to the public spectacle of having liquid feces running down both legs.
The cure for runner's trots is to become a fitness walker. That switch will cause you less distress and embarrassment. And you don't have to time those meals around your training anymore.

The Worst Book Ever
Fortunately all photographic evidence has long been destroyed, but there was a time when I briefly belonged to the barefoot running cult. This was roughly ten years ago. Like millions of others, I read Christopher McDougall’s Born to Run and realized that I’d been duped by big running shoe companies who had sold me something that I didn’t actually need. Newly enlightened, I did the only rational thing and spent $160 on a pair of shoes that mimicked the sensation of running barefoot. I felt sorry for the idiots I saw on my daily park loop who were still caught in the cushioning-is-necessary matrix. I exchanged nods with the local hippie guy who always ran in sandals. After a few weeks, however, I became disillusioned. The anticipated breakthrough in my running never came. What’s more, none of the top professionals seemed to be ditching their plush footwear and going minimalist. If they weren’t doing it, why should I? In the end, I was relieved to go back to wearing regular old running shoes; my feet were really starting to hurt.
When you dig into McDougall's claims, you find that he is a first class bullshitter. Here is what Jamie Compos wrote about the minimalist running thing:
So I did some runs in my fancy new shoes and it felt liberating. I even did a spate of barefoot walks on all types of terrain, and some sprints in grassy fields. I tore out the cushy insoles from my work shoes and got some good ol’ Chuck Taylors (minimalism incognito) to wear casually.
Everything was going well. So well, in fact, that one day I decided to do several squats at the gym, followed by a 6-mile run – more than double the distance I’d attempted in my minimalist shoes to date.
My knees were screaming the next day, and remained extremely tender for weeks.
Thus endeth the experiment in minimalism.
The injury frightened me so much that I gave up running for several years. Dual obsessions with backpacking and running are probably not good on the knees. A friend’s comment while we were out on a beautiful backpacking trip sealed the deal:
“I’d rather be able to do this in old age than risk it all on running,” he said.

The claim from barefoot and minimalist enthusiasts is that runners have to allow for an adjustment period until you get used to running without all the cushioning of a modern running shoe. This sounds almost identical to carnivore diet enthusiasts who tell people to allow for days, weeks, and months as you suffer explosive and chronic diarrhea until you "adjust" to the new diet and become chronically constipated. With a vegan diet, your health is already improving after a few days. But I digress. . .
I am going to tell a different story. You can agree or disagree if you like, but I think my tale is better. We were never born to run just like we weren't born to swim, fly, cycle, row a boat, or sweat to the oldies with Richard Simmons. We were born to walk. This is our natural movement. You begin as a toddler with a few unsteady steps and progress from there. Walking injuries are rare relative to running. You feel better when you walk. You don't feel better when you run. Our bodies are designed to walk for long distances which we are able to do with little difficulty or distress. In comparison, chimpanzees are terrible walkers but outstanding climbers. They were designed to climb. It is their natural movement.
Human beings did not develop big brains from eating meat from persistent hunting. Humans always had big brains, and those brains have been maintained by starches derived from farming. The energy we require to walk and work comes mostly from carbohydrates not meat. Carbs are the preferred fuel source for human beings. I don't know how persistence hunters can run all day while bonking on a meat diet.
McDougall is at pains to argue that endurance running is natural to humans. Yes, humans have great endurance and sweat like horses. We can go all day when it comes to walking and working. The running thing comes up short with the injuries. This leads us to the next big myth which is ultrarunning.
Ultrarunners do not actually run ultramarathons. They run and walk those extreme distances. A marathoner is able to cover a marathon while running the entire distance, but ultramarathoners are incapable of doing that with ultramarathons especially those 100-milers. They shouldn't call it ultrarunning but speed hiking. Here is what Heather Hart wrote:
Here’s a bit of a reality check for new (or non) ultra runners: you’re likely going to walk during your ultramarathon. The longer the distance, the more you’re going to walk. But don’t worry: walking during an ultramarathon is quite normal – you’ll even see the elites power walking up some steep and gnarly hills.
But for whatever reason, not a lot of people seem to know that.
https://relentlessforwardcommotion.com/ultra-training-101-ultramarathon-walking/
The reason not a lot of people seem to know that is because ultrarunners hide the truth about the walking while embellishing the running. I would like to know how much they walk in a typical ultra, but I will guess 50%. Some researcher needs to use fitness tracker data to get a true picture on the ratio of running to walking in an ultra.
Why do ultrarunners have to walk? That is obvious. Human beings are not born to run. Running long distances is unnatural for us. But we can walk those same distances though we do it slower. Ultrarunning is just a great way to ruin a hike.
If you believe the ultrarunning myth that ultrarunners run the entire 100 mile distance, you will buy the born to run thesis. The reality is they don't run the whole way. That brings us back to the shoe issue.
Neither cushioned trainers nor barefoot shoes make any difference. If you run, you will have running injuries. No shoe causes or cures these injuries. The running shoe industry won't tell you this because they make bank off of your search for that magic shoe that will cure those injuries. This is why they never make those injury prevention claims. When Vibram made those claims, they got sued and lost.
Running injuries have one thing in common. They are all sustained while running. When you stop running, those injuries clear up. This is the number one advice for healing running injuries. Stop running.
When it comes to cushioned shoes, they certainly make walking more comfortable. When people walk, they heel strike normally. This is why shoes for eons have had stacked heels relative to the forefoot. That is the point of first contact when walking normally. Forefoot striking is abnormal for walking on level ground. Forefoot striking comes into play when going up steep hills. You can walk barefoot, but this becomes painful very quickly. This is why people like carpeted floors and rugs.
Born to Run is a bad book. Unfortunately, it still remains influential. It was a microfad in the larger fad of running. If there is one upside, Born to Run has made some people give up running when they finally rejected the hype. A better book to read is Shane O'Mara's In Praise of Walking. The big complaint of that book is that it is very scientific and has a ton of evidence and research that can be wonky to read. I don't care for the evolution arguments O'Mara makes, but the book seems solid in its presentation which makes it the opposite of Born to Run. O'Mara isn't full of crap. I think runners should switch to walking and do that walking in comfortable shoes.
UPDATE #1: I enjoyed this comment from Ben so much on one of my sources for this post that I wanted to share it.
To me, the issue isn’t whether barefoot running is better than running using cushioned shoes, but whether humans are truly ‘born to run’ at all. We can run long distances, certainly, but did we evolve to do so, or are we to some extent ‘misusing’ our biology?
The persistence hunting theory, often used as an evolutionary explanation for our running ability, has been debunked as unscientific. It has about the same standing among anthropologists as the aquatic ape hypothesis. Studies of extant hunter-gatherer societies show that some never run at all – never.
All in all, it seems that running is something that we (or some of us) can do, but we don’t have to do it, it isn’t necessary to be healthy, and its importance in our evolution has been overstated (or at least misstated – no doubt occasionally running from predators or towards prey is very useful). It’s an interesting issue, and personally I find McDougall’s mythologising of running and running culture doesn’t contribute in a useful way, whatever its practical applications for runners or effect on the industry.
