Running is harder for me but I still like to do it semi regularly to maintain the ability. There are real life situations where it could come in handy, and not just for when being chased by bears! 5k is the most I do, but I have placed in my age group on timed events several times. I suspect doing much longer runs regularly would beat up my body, while doing long bike rides won't.

A bicycle has wheels.
Any wheel, no matter how big or small, is a flywheel.
And the flywheel is essentially an energy storage device, an energy accumulator.
The battery of energy can be charged and can give it back.
Where does the linear inertia of the bike and the rider come from?
Of course, from the untwisted flywheel wheel.
An example of removing energy from a wheel is a dynamo.
The mechanical energy of the flywheel is converted into electrical energy.
On fixed gear power wheel flywheel connected to the cranks - pedals hard, and Cycling with the free flow of energy in the crankset - pedals not, reverse the mechanical connection is broken due to the overrunning clutch.
Thus, the mechanical energy of the entire rider bike is always present on the fixed gear crank pedals.
In a transmission with an intermediate shaft, this energy is not even added, but multiplied.

I don't mean to pick, that's why I originally asked you to explain in non-physics terms. Energy added or multiplied by the transmission isn't a thing - just some advice here, take or leave it, but you should find a another way to describe your concept. The physics analogy doesn't work.

Ups!
We don't call it a flywheel when the rotational inertia is insignificant. The linear momentum comes from you forcing the wheel around - the opposite effect of a flywheel.

This fixed fear weighs 10.4 kg, average speed 20 km / h, maximum speed 40 km / h:
But this bike weighs 17.5 kg, the average speed is 22.2 km / h, the maximum speed is 47.5 km / h:
If it's not physics, then it's magic.
Or the wild euphoria of owning a new thing?
What's wrong with physics?
Why is everything turned upside down?
The maximum speed of 47.5 km / h is not the limit for this magic bike, which accelerates itself.
Fixed gear and so go by magic, they do not even need to turn the connecting rods - they turn themselves.
On this bike, the long-range connecting rods spin twice as fast as the fixed gear!
Magically spin themselves!
I am an old, decrepit, sick, infirm old man of 100 kg weight, with an average power of 70-80 W, became a wizard, spat on all the laws of physics and began to drive even faster!
And even added power to 110-120 watts!!!
He must be crazy ...
It is mystic fixed gear.
It is not easy to put into words. There is an almost mystical connection between a fixed-gear cyclist and bicycle: it feels like an extension of your body to a greater extent than does a freewheel-equipped machine. If you are an enthusiastic, vigorous cyclist, you really should give it a try.
Sheldon Brown

It seems like fixed gear is very simple, but in fact the scientific physics of fixed gear is very complex.
Sheldon Brown almost made it up New Fixed Gear.
I feel very clearly on my own skin the mystical connection between myself and the fixed gear bike, as an extension of my body.
To fixed gear who did not ride it, you need to get used to some time.
The New Fixed Gear also needs a habit.
No one in the world has ever ridden it, so I can share my feelings a little.
I'm still dumbfounded and not used to it.
You drive like a limousine.
And I'm not used to it yet because of the short time riding it - it's like getting used to fixed gear - it should be some time.
On fixed gear, you get the joy of driving and euphoria like a drug.
On New Fixed Gear, the buzz is harder and more deadly.
When, after a trip to the New Fixed Gear in the garage, I changed the bike and immediately sat on the fixed gear, there was a moment that I kind of unlearned fixed gear again - somehow it seemed fragile to me.
The internal energy of the entire New Fixed Gear system-the racer, turned out to be simply stunning.
I was having a great time!
It was like I was under the influence of drugs and I was experiencing a state of euphoria from drugs.
All in all, full of Buzz!!!

Let's get away from physics and weigh the bikes. We measure their average and maximum speed.
This fixed fear weighs 10.4 kg, average speed 20 km / h, maximum speed 40 km / h:
But this bike weighs 17.5 kg, the average speed is 22.2 km / h, the maximum speed is 47.5 km / h:

it's almost entirely your position on the two bikes, and how you've adapted to riding them.

Nothing is wrong with physics, when it's real physics. I'm sorry, but what you're presenting isn't really physics. If I didn't feel you were earnest, I'd be insulted because people trying to BS you will often resort to "dazzle them with science" and the fake science is insulting. But I think you ARE earnest, so I'm trying to help.

Since I have already tried New Fixed Gear, I subjectively feel and even know that I will go even faster in the new season.
This is just on the available pre-gear 177 inches will go.
The next stage I will have is a 200-inch transmission.
I will not paint the physics of magic, but I will show the star 15t for 200 inches:
(48T/15t)x(53T/22t)x26"=200"
And I would also like to ask you, on what basis are patents (inventions) made - on the basis of magic-magic or still on physical principles?
Do you seriously think that inventions are made just at the click of a finger?

Ups!
I was not going to argue with anyone, but just show the phenomenon of the new program as it is.
There were no such programs in the world, it is completely new.
And no one but me can say anything about her. While on this gear, I "overtook" my standard fixed gear - this shows that the idea is working.
I will continue to work on this program no matter what.
If I really want to amuse my ego, I can document the scientific discovery of the phenomenon of fixed gear recovery.
The formula for the discovery has already been drawn up, it is up to the scientific physical society to formalize and prove it.
And I will say this about inventions - they are secondary to physical discoveries.
On the basis of scientific discoveries, inventions are made in whole bundles in their field of discovery.
I already have a lot of projects on the new gear-both cargo fixes and snowmobiles and stappers.
A lot of toys were born right out of nowhere, such as have never been before.
And all because of the opening of the recovery.
So these constructions would lie in ignorance, no one would know about them.

I once rode a motorcycle in the woods.
In parallel to me, a man ran with his training.
I love to photograph the forest and nature.
So I would stop, adjust the camera, and take pictures.
And that runner passed me riding a motorcycle.
What had he seen in the woods?
He couldn't see anything, just a strip of road ahead of him and a wall of forest around him.
I've seen the wonders of the forest.
Dew, grass, bugs, the sun, the play of shadows, cobwebs, leaves, flowers.
So I don't like stupid running. It should be combined with the contemplation of nature.
Then running is a walk and that's good.

Running definitely harder overall. It's harder on the body (joints etc). Furthermore, Even moderate running will have you out of steam sooner than moderate cycling. Nevertheless, you can also punish yourself just as much going all out on a bike. Especially on hills.
Cycling just has a bigger range of effort from recreational up to all out cardio.
I also find that it's easier to get back to fit on a bike after a long period without sports. Running just causes aches and pains to occur sooner, and the older I get, the more likely it is that they become long lasting injuries.

Running is far harder on the body. Have you ever seen slow motion video of the shock waves running up the leg from the foot??
For me by far the easiest thing to do is to cycle on a trike. No worry of tipping over and falling, Ride as slow as you want, and your feet can stay clipped in at stop lights.

Try telling my 70+ y.o. friend, who was along on a 32 mile ride, while still wearing a knee brace from a knee replacement, that bicycling is more difficult. I think you're confusing "convenient" or "riskier" with "harder".

This month (March 2021) I have been “a runner” for 45 years. About a dozen Marathons, dozens of ½ Marathons, and lots of other races and runs in that time. As a 9th grader in the in March of 1976 I joined my h.s. track (and CC) teams and just never stopped running. I took up cycling and swimming about five years later when I wanted to get into the new sport of triathlon. There’ve been numerous running injuries over the years. Lots of pounding the pavement. Wear and tear on the lower joints. Consequently...today...running (really it’s only a jog now) is WAY harder. For all intents and purposes I shouldn’t be running. It’s painful. But I’m a runner at heart, and I guess you can’t keep a good runner down. So I merely go through the motions for about five miles about once per week. Otherwise I’m on the bike (or swimming).

Running is harder, much harder, that is why the bicycle was invented.
I very rarely, almost never, see runners that are older than me.(~60), I would say 40-50% of the cyclist that I see on the roads and bike paths are older than me, this might be specific to the area and hot and humid weather (Palm Beach and Martin County, Florida) but this is my unscientific observation. If you are 60+yo even relatively slow 5k running (10-11min/mile) in hot and humid weather is a challenge to your cardiovascular and skeletomuscular systems. OTH, biking has advantage of extra cooling, and easy choice of speed from easy almost no effort ~10mph to somewhat challenging ~18-20mph. The best about running, cycling and swimming is the advantage of cross-training.

I ran track in high school and continued to run to reduce work stress through my late-30s. Unfortunately running was a constant recovery from injury. I constantly pushed myself to greater distances and faster miles resulting in Shin splints, pulled muscles, increasing back pain. I loved going out for an hour and feeling well exercised. Ran tons of organized fun runs for best times. The injuries and pain made a transition to cycling easy. Cycling was great on the back, no shin splints and just occasional leg cramps on century rides. Cycling is as easy or hard as I want to make it, while running doesn’t afford the same amount of flexibility unless you consider jogging running.
I did limited running into my early 60s during the wet winter months to get a fast workout but after getting plantar fasciitis I gave it up completely. Now its 100% cycling combined with daily 3 mile dog walks and hiking.

Running is only realistic for thin people. It is too difficult for fat people.
As we get older, I am concerned about injuries. Cycling is low impact, so less likely to cause injuries to knees and ankles.

watts is watts. just different stress points and impact, different muscles deployed. whatever you train for is easier - shocking.

This. Finally some common sense.
OP asked a stupid question and got a lot of stupid responses.
How many 50+ people can hop on a bike right now and ride 3 miles?
How many 50+ people can lace up a pair of sneakers right now and run 3 miles.
End of thread.

I wouldn't be so quick to call it a wrap. There's a whole lot more to difficulty than just the watts, and after training both later in life I can't at all agree that what you train is automatically easier.
I could double or triple my running miles and it still won't make it any easier than cycling, even for short runs. On the other hand, when I climbed on a bike at my late 40's it was darned hard. Three miles was hard. It DID quickly get easier so I see where that's coming from, but at this stage in life it's taking a lot more for the same kind of gains in running and jogging.
It sounds like I'm arguing both sides, but I'm really saying it's just not that simple.
