I did go to the gym last night and hit the treadmill for quite a while. Towards the end of my workout, when I was slowing down for my cool down, I snapped a picture of what I had done. I am including it here:

Yes, that is over 2 miles done. I averaged 3.4 mph, and had a vertical distance of between 400 and 500 feet.

All in all I felt really great!
