+1 on the dry run. 10 miles isn't very far, but hills and wind can make it seem that way.

+1 on being visible. Get a rear blinky LED light and either a front blinky white LED light or powerful headlight.

I don't see why riding the wrong way is dangerous. I know it is not recommended, but It increases the closing speed, but it gives you the chance to spot a drunk or someone who is "driving while intexticated" before they're on you. It is a mixed thing.
