From 368lbs to 15 mile runner:)
Thanks, it took me about 1:40 hour to complete. I dont focus on speed for now. If you get too out of breath i slow down and pace myself then build back up. I also alternate incline levels to give me more challenges. I think what i'm doing is great no matter if its outside of treadmill. I've been training for over a year, i started out on the ellliptical then mastered that for 5 miles. I try to give my body challenges and my body responds back. You will get there too.
