Yeah. BAD idea.
I only had it on 6mph and a 5% incline (with about 2 minutes of 15% incline insanity thrown in)...only ran a mile. Still managed to find myself nearly passing out because I couldn't catch my breath. Also, my heart was beating so fast I felt it was going to jump out of my congested chest. Nice visual, eh?
Oh well. My fault for pushing it a little too much on the incline. But hey, I ran a mile! Woo hoo! And I'm alive to type this little post! Double woo hoo! Now, I'm off to attempt a little germ homicide via mouthwash gargling.

Oh, it's ON.
