Another Solo Run-Walk

I decided to run/walk outside to enjoy the beautiful morning. I used my Garmin Forerunner for mileage and the Gymboss for interval timining, and went 3.37 miles in 56 minutes, a 16:37 avg. pace. Here I thought I was going faster than my solo run last Friday, but it turns out I averaged about 20 seconds more per mile today! Yikes! Granted, I went about a mile and a half longer today than I did on Friday, and that's worth something! Still, I really want to speed up. Maybe I'll start working in some speedwork.
