Enjoyable run

Yesterday I went for another trail run, but just took it easy. I didn't bring a watch or Garmin, just ran for approximately 45 minutes. I found a trail that is very muddy and has some difficult terrain. I almost fell on my face for the first time, but caught my balance at the last moment. Everything that I read says eventually I'll fall on my face, but I'm going to try not to let that happen. I am having a lot of fun in this new sport.
