When I first started out, it took me 30 minutes to walk a mile.

Now, I can do a 12 minute mile and have jogged up to 4 miles non-stop.

I no longer use a treadmill. 30 minutes on the treadmill will cause my thighs to go numb, followed by sharp needle like pain. Weather permitting, I go outside for my walks/jogs. Hooray for summer!!!
