I've just gotten back into running. I did 10 miles last week (in one go) and 8.2 miles (Wednesday) on the elliptical. Each week, I am averaging around 20 miles a week. So, I decided to take that stamina to the treadmill. To my huge surprise, I could do 30 minutes jogging without stopping. I haven't been able to do that since I was 15 (26 now) and before my knee injury. I took that outside today in the hot sun and was able to jog 2.2 miles at a slower pace (looking at a 12 minute mile). I'm disappointed that I am so slow but I guess it could be worse for a beginner. I'll try to work on the speed and the distance outside. At least I can jog more than 50 feet without feeling I was going to pass out.

Do you guys use the Nike+ Running App? I did today and it was actually great and accurate.
