Yesterday, the gym was closed when I went, so i chose to run outdoors instead. Currently at week 6 day 2, I was supposed to run for 20 minutes. But, a big letdown. I was barely able to run for 2-3 minutes. Had to stop continuously. Very disappointed. Going to gym as per schedule tomorrow. Treadmill is a bit less intimidating than outdoors. How am I going to do my 4K run on MAY 20????
