Whirly. I can't believe that you would think such a thing.
And besides I know you guys are right because I did a simple experiment.
Tonight when I was at the gym I had a run on the treadmill and while I was running a long at about 7km/h I realised it was exactly like flying into wind. As long as I didn't look at the ground my speed was 7 km/h relative to the treadmill.
And because I know you guys are right I knew it was safe midstride to turn around and run with the treadmill. Yep you guys were right, I never ended up on my arse or nothin.
You guys should try it too.
