Total of 44 miles - first half all downhill and the second half an incline of no more than 2% - just enough to slow you down a little. Got the clean air and even some rain and mud so some bike clean up is necessary. The best part was my first opportunity to ride through an old railroad tunnel - this one is said to be 2 miles and I believe it. My light was sufficient but not great. Once the eyes adjusted after the first quarter mile the going was ok with the trail being so smooth.

The "roughest" part of the trail:

You get to ride through some cool stands of old growth forest

And over several trestles - this one the longest
