you can always hit a wall, but they will make it harder to do so. the course can be run a number of ways, but its mostly a large oval you run the same direction per run, easy to get some decent slides but still short enough the underpowered guys arent gonna be screwed.
regardless, it was good fun for a couple of runs just testing the place. also, if the staff want to mix it up you can run it the other way and have right turns every other run or whatever.
