I was doing it for a while last summer. I'm terrible at running and was able to get up to a 2.5 hour run, although 1.5 hours was a lot more enjoyable. I liked just going out there and seeing where I could go. I found some really nice horse trails and jogged through some real nice parts of town and just found it to be kinda relaxing and adventurous at the same time. I wore a heart rate monitor to keep track of my heart rate and stay where I wanted it to be.
