Skinny runners, fat cyclists

Notices
Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

I assume bigger folks try running and realize the severity of impact is damaging them and quit.

Then try cycling and find out they can do it without injury.

Tiny, little people can run without hurting themselves, so they keep going.

Process of elimination essentially. That said, I don't know any older runners (skinny or otherwise) that are not damaged from running.

That said, the majority of runners and cyclists I see are "skinny fat"

Meaning very little muscle and lots of saggy skin. Chronic cardio does that to you.

Because cyclists use Strava, and runners use Starva??

(not as good as @dr_lha's but maybe second place)

A lot of overweight people start off cycling to try to lose some weight before going to running, and wind up:
a). Getting hooked on cycling, or
b). Not losing any weight and getting stuck in cycling . . . . because it's murder on the knees to run carrying a lot of weight.

You can start out running when overweight, but I don't think you'll last too long. It's unsustainable, whereas sitting on a saddle spinning your legs at a leisurely pace is a piece of cake by comparison.

I wonder if in another few generations whether we will see human knees getting stronger and more durable due to evolution. My bet is yes, mankind will adjust to running on harsh paved surfaces.

It's circumstances, depending on fitness level, weight and terrain your opinion is wrong.
To the point of the OP, whenever I finish a run I'm not hungry but after a bike I'm starving.

Does being able to run on hard surfaces significantly improve one's chances of successful reproduction in today's world compared to other competitive factors?

I was heavy and used running to lose 60lbs. I would run 60-70 miles per week. I would never eat 2-3 hours before a run. During a run I found it near impossible to take in nutrition without feeling nauseous. After a run I would struggle to drink a chocolate milk. It would be 2-3 hours before I felt like eating anything. Many folks will eat breakfast or take in some nutrition before a ride. During a ride of duration many/most will take in some type of nutrition. After a long ride I will be ravaged. I will pretty much eat anything which is not tied down. Hence I put the 50lbs back on.

Energy used running at a given pace is proportional to body weight, so fatter "runners" end up "jogging" or "walking" instead.

Cycling on flat ground at reasonable speeds your power requirements are dominated by what it takes to overcome aerodynamic drag. With its force increasing with the square of velocity, power to overcome aerodynamic drag goes up with it's cube and octuples for twice the speed. Rolling resistance is a constant for a given weight and power to overcome linear.

An extra 50 pounds (22.7kg) at 20 MPH (8.9 meters/second) on a road bike costs you just 22.7 kg * 8.9 m/s * 9.8 m/s^2 * .004 Crr = 8W out of 200, or 4%. Losing 8 of 200W only slows you down about 1.3% which is 0.3 MPH.

Down-hill fat cyclists are faster because their increased sectional density produces a higher terminal velocity.

Climbing speed is inversely proportional to weight at a given power, although we don't have a different name for "slow cycling up hill"

That would only happen if most people's knees hurt too much to lie down together. Or if people enjoyed complaining about their knees so much they never had time to do the deed. Without selective pressure, it's just an unpleasant side effect of evolution, like having bad backs and needing glasses.

Jogging is a type of running. And runners who walk aren't runners, they're walkers.

It has been a while since I've run a marathon, but the last one, there was a good percentage of the runners who weren't super lean.

With any sport (other than Sumo Wrestling), as one moves up in the ranks, the bellies get smaller.

So, lots of cyclists that can do a mile on a cruiser with little extra "fuel storage".
But, start hitting the 100 or 150 mile riders, and that spare fuel storage becomes minimized.

And get into competitive racing, and they do get really lean.

You see more fat swimmers than fat cyclist. There are several larger people in my masters swimming that are fast. They all swam in college.

I sink in freshwater, or at least I used to sink. "Floating" was never relaxing at all.

A little added buoyancy might actually help swimmers.

You haven't heard about the big man run an it's variations? Run a bit, stop for a hot dog and beer, run some more, repeat...

Running is hard, mentally and physically. You've got to be pretty disciplined (or masochistic) put up with the misery of an hour-long slog. And no. There's no coasting. So I just think these people are just more disciplined with their diet too. Plus an hour of running almost always burns more calories than an hour of cycling.

You people can argue this until the cows come home. Amateur athletes in all sports come in all shapes and sizes. There is no answer.
