Finished W5D3 tonight!! Happy dance time! 
My trainer from the gym actually drove into town to run with me after work. I was so glad because today was one of those days where I did not have 'it'. It was not easy but I made it. I will start week 6 tomorrow or Thursday.
For me, I don't know if it is necessarily the treadmill or outdoors that makes a difference, but how I feel. Some days are blah and I have nothing like tonight and I just go and move through the routine. Other times I feel great and the routine is no big deal.
