I started out with no planned route. I just ran south across the highway and started turning whenever I felt like it. I ran some streets that I hardly ever run on, got scared half to death by a dog I didn't see before he barked in a deep husky voice, ran some little hills and enjoyed the beautiful weather. I didn't really push the pace or hold back. My pace was dictated by feel and I felt pretty good.
Now that I've got my first post-vacation run in, I hope I'm ready to kick it up a notch in my training. I've got a 100-miler to run this fall. (garmin data)
