Hello, my name is Al. I am 49 and have been thinking about running for awhile now. The last time I tried taking it up was 10+ years ago. It didn't last long, think I started to fast and didn't learn right. So here we are, found this app latest week, went to local running store and bought shoes today, and completed week 1 day 1. Im sore this evening back no worse than what I expected. Looking forward to Tuesday now.
