I don't see why it shouldn't - you're still working to go through the wind, aren't you?

It only represents wind resistance beyond zero wind with running on non-moving surfaces when it is blowing directly at you, over your entire body at a speed faster than you are actually running on the treadmill. So if you are going 9 mph on the treadmill and it is blowing at you at 10 mph, it is like you are running against a 1 mph wind. Make sense?

Math is demonstrably not my strong suit... But I think the above reaponse is incorrect. 1mph wind will be 1mph wind, whether you are running in place or standing in place.
This thread has potential...
Unless your fan is generating some massive airflow then it's probably helping you more than hurting due to the improved cooling effect the fan provides to your skin.
This is why I run on the treadmill with a giant fan behind me. I get the benefits of cooling plus a tailwind.
Thejeff.... Not again... You should really know better than contributing to a physics thread.
i think the plane would take off in this case
Put your phone in front of the treadmill and tune into LR. The bloviating will provide all of the wind resistance you will ever need.
if you somehow set the air velocity of the fan to the speed you are running, it would replicate wind resistance quite well bug it would take a pretty big fan for the airflow to be anything as uniform as you'd experience running on a normal surface.
Is the treadmill itself moving?
Is there a slope to it?
Is the treadmill moving uphill over time?

Yes. It's inside an RV driving up the Rocky Mountains.

Not really necessary. Just have the treadmill mounted on a flatbed and have the truck's cruise control continuously adjusted to match the treadmill's pace.

OK. Well, in that case the BIG fan would need to be locked into its Rocky Mountain setting. If you do this then it should replicate wind resistance for runners under 150 lbs.
I always put my biggest fan in front of the treadmill when I run. I love having someone there to cheer me on.

You're using the right brain power, but not in the right way.
Imagine a wind tunnel and a 100mph fan. Standing still (0mph velocity), you will feel 100mph of wind knocking you over. 10mph of wind from the fan, and you will feel 10mph of wind pushing you.
You are right, that if you stand on a treadmill tuned in at 10 mph, and the fan is blowing 10 mph, you won't feel anything; your velocity relative to the treadmill is 0, but -10 mph relative to the fan, room, and wind from the fan. But if you're running, your velocity relative to the fan, wind, and the room is 0 (velocity relative to the belt is 10 mph).
This website thing here gives some specs:
http://www.bealecorner.org/best/measure/fan/fanspeed.htmla regular fan at 100% efficiency would blow 14 m/s. But the measured data showed 15% efficiency, so 2.0ish m/s. The math gets more complicated than my skills, but that does not translate to the actual force you're running into, because it depends on where the fan is, how big it is, and other factors detailed above.

Congrats, You just won the stupidest person that ever lived award.
It's totally different because the air hitting you is turbulent. If you go running at the same speed in 0 wind, the air is not turbulent.
I don't have numbers but turbulent air is way different from non-turbulent air. It will knock you sideways and shit.

You are so uneducated it's hilarious!
He's plain dumb.
Run outside in zero wind and there will be all kinds of turbulence around your body. The lower pressure at your back may constitute around 1/3 of the total drag.
Running on a treadmill is like running outside with a 12 mph wind at your back.(my 5:00 easy pace)
Running at 1% incline is like running outside up a small hill with an 11.5 mph wind at your back.
Running on a treadmill with 2 inch blocks on the right front and back is like running on a cambered road.
