Why does treadmill at 10mph/3% feel like a similar effort to 5:00 min/mile pace on synthetic track?

It was probably calibrated by liberals

It could be the environment the treadmill is in. How is the ventilation, cooling, temperatutre, humidity, etc. Treadmill running is harder usually because gyms are setup so people will feel comfortable not exercising or doing light exercise, not running at sub 6 minute pace. Just like you wouldn't want to go for a hike at 40 degrees, running would be pleasant at that temp.

Sounds like age, poor fitness, and a lack of testosterone are catching up to you. Time to take up pickleball and power walking!!!

5:10 pace on a treadmill feels like 5k pace for me. It's basically my threshold.

I like treadmills for 6:00 pace but anything faster than 5:20 feels like a sprint

Because you're not used to running on a treadmill, so it feels more difficult. Your muscles are being used differently when running on moving ground vs still ground, which causes a different stimulus than you're used to. So running on a treadmill feels more difficult.

pssst. A treadmill isn't reality, as in most things you experience.

If you don't feel the wind in your face you are not running.

Even indoor? :)

It's not always a popular opinion here. But if you use a public gym treadmill, they can be wildly inaccurate as to pace. Either faster or slower. The one mill at my gym is at least a minute slower than the pace it gives on the screen. So if I think I'm running at 8:35 pace, it's actually 9:35 pace.

10 mph @ 6% converts to 5:00 on my treadmill. More like 7% on my old gym's treadmill. The conversion charts are in the right ballpark

^^ This.

What are you doing? It's not even raining!

If you don't feel the rain in your face you arent running.

A University in England actually did a study on this:

An old wives' tale or fact?

3% at 6:00 pace should feel harder than 6:00 pace, but not much that much harder.

Well, I know that, but I was just trying to think of something nice to say about being outside in Seattle, and considering my audience, I figured that was about the only thing that would fly. But yeah, like you said.
