If someone is doing tempo work on a treadmill, how much faster could they go as opposed to on a track (with ideal running weather). If someone is going 5:20 pace on a treadmill, maybe equivalent to 5:50 track?
5:00 treadmill, 5:30 track?
It feels magnificent to run on a treadmill quickly, wondering what the conversion is.
It's almost impossible to really say in my opinion.
I find treadmill paces to be very accurate for me. Over the winter I was running tempos at 5:30–5:40 on the treadmill. A few days later I'd do one outside and run just about the same pace, often a bit quicker because I was more engaged and excited to be outside.
There's a lot of factors that come into play: * Mental, treadmills are boring * Heat, you get overheated on a treadmill quickly and sweat A LOT. It's tough to run fast when you're absolutely soaked in sweat * Individual treadmill quality and calibration. Not all treadmills are equal.
Ask yourself, would a plane take off if the runway was a treadmill?
There is a man at my running club who has never run under 19:40 in a race (usually 20 mins actually) but has run sub 18 on a treadmill. I rest my case.

A plane would indeed take off on a treadmill. The plane doesn't rely on the mechanical friction between the wheel and ground to move like a car does. There would be some friction incurred due to the wheelspeed needing to be higher due to a moving surface beneath, but that has zero impact on the force being generated via the engines.

Think about it like this. The car takes the ground and pushes it behind the car via the tires. The plane grabs the air and pushes it behind via the engines. The wheels are just there, along for the ride. Now, if for some reason the treadmill moves so fast that it incurs enough friction in the wheels, it could slow it down, but that's not practically happening.

HAVE you ever seen a plane take off on a treadmill? No.
Have I ever seen that running club member run sub 18 in a race? No.

I'd like to add that an individual's mechanics also have an impact. My friend, a smart person and good runner, has always claimed that he can run tempos way faster on a treadmill. He has a very loping stride, long legs, with lots of hang time. So I imagine the belt moves under him more than a "regular" person.

Why do people still keep having this silly debate? If you don’t have the physics chops, just look it up. It’s been plentifully discussed including on this forum under what assumptions it would or would not take off.
