Lunar racer 2 not a technical trail shoe

Stopped at a Penn state park on my way home today to get in my run for the day. The first 2 miles were basic lakeside trail, the I ventured off onto some hiking trail, which ended up being ridiculously rocky at times which make a decent pace impossible. It was also raining which made the rocks that much more dangerous. I turned around 2 miles in, because it was just too much for my liking at the time, and I didn't plan to run over 90 minutes. So I think I had ~ 4 miles of today's run at ~ 9 min pace. No biggie, because it was still a nice run. I finished with 90 min on the dot, but I am reluctant to call in more than 11 for the day.
