Training Day 36/56 days til Marathon

Today my plans did not go quite as planned. I set out to do a 10 mile trail run. I have done a couple trail runs in Middle TN, but the trails there are lot different. They are wider and easier to navigate. The trails ran in past had rocks, stumps, roots, etc, but today's run was different. Today I ran Arrowhead Trail through McKay Hollow in the Monte Sano Park area. The trail was very narrow, not many markings to mark the trail. The trail had many rocks, roots and stumps. Some of these rocks were pretty sharp, my feet felt every step at times, since I run in the Vibrams. The trail was also muddy due to all the rain in the past week.
So like I said, trail run did not go as planned. I only ended up doing 5 miles. I started out jogging for the first 2.5 miles, slow pace, especially since never been out on this trail before. After 2.5 miles my jog became a hike. I stomped my big toe and 2nd toe on the left foot 2 times as I was on my return hike. I seem to always hit these 2 toes when running trails.
I learned during this run today that trail running is more technical than road running. You always have to scan your area to plan your step. I think I will stick to the road runs for now, but will not rule out trail runs in the future.
So ended up with 40 miles for the week instead of 45. But still a good week.
