Treadmill Vs Jogging - Exercise Intolerance Of The Latter

[KevInChester1]

When I've been at my peak of health I've been able to run on a treadmill without too much issue - I can even put it on a decent gradient and speed and still be able to run for 30 minutes or so. The first time I did this I surprised myself as I didn't think I'd even last a few minutes.

Jogging outside I am unable to last for over a minute, my heart pounds, I feel sick and dizzy.

I know there are differences between the two, the main one being that a treadmill doesn't require you to propel yourself along as the road moves for you. Would this make a substantial difference in explaining why I can tolerate one but not the other?

Years ago, I use to run in the gym on a treadmill then I took up outdoor running and I remember it being a lot harder to run outside on the road. I'm sure there is some Info somewhere on the web about this.

Could it be the climate controlled environment of the treadmill vs. the variables of the outside environment?

Yeah was looking into it, seems that the main factors are:

Not needing to expend as much energy to propel oneself

Climate

and the fact you are running on a smooth non changing surface

Guess they should all add up to make one doable, and one just not doable at all (well without a lot of training). Perhaps even just those add enough to the blood flow requirements to trigger me.
