when you're running on a trail you've never been on and have no idea where it goes/ends

person 1: I just went blind running on the trail near hudson bend!
person 2: how long was it?
person 1: 4 miles, but it was a very scenic run!
person 2: cool cats.

Running a blind red 

Run a red light without checking the surrounding to make sure it's safe to run a red light and causing a crash.

That man was an idiot for running a blind red and because of that the bus driver and kids are now six feet under.

Blindrunning 

Something you say when you're the last in Search and Destroy and you just look to the sky and run. You subsequently humiliate an enemy player after they can't hit you.

Holy shit! How can that guy not hit *gamertag*?! He's blindrunning for god's sake!!
