I finally figured out how to get the guy really running. Everything was going great. Then I got to about 50m and all of a sudden there was this stupid hurdle and I ran into and fell.
I have the run going pretty good now. I start with pressing "O" so he leans a bit...then i lift the back leg forward by pressing "Q" and "P" at the same time, then "W" and "O" (and so on back and forth). The main thing to keep balance is to have the back leg hang lower than your front one so the runner follows a bit of a skipping motion.
