Girl, you must be built to be a runner!! I just started jogging my "10" about a week ago. (I treadmill for my 20'MAS and walk as my knees are in bad shape and with an extra60lbs on them right now, I didn't want to do any more damage. However, I felt 1' wouldn't hurt and so far it hasn't.) Anyway, after reading your post I thought I would try 7.0 - How hard could it be?? The treadmill was just getting up to speed when my brain realized my feet and legs were not doing the work required and in fact the whole system was in jeoperdy of failing. (I about fell off that #~!& thing!! ) I got it slowed back down to 6.0 for the rest of the minute, but it about did me in! I think it will be quite some time before I can run that fast for even just 1 minute!

My deepest respect and more power to you my fellow BMBFLB!
