He gets more points for reaching the second field, and even more points if he can traverse that entire field. He keeps going until someone finally brings him down.
Now, the defensive team can choose to chase the guy, or they can run around in the other direction to stop him on the other side. If a guy is really fast and he scores, some of the defenders may chase him and others will run the opposite direction so they can stop him on the next lap.
It would be loads of fun.
Just make it a 110 yard oval with two 5 yard end zones. You get 3 points every time you cross an end zone. The interior oval (non playing surface) is divided into two regions that replace the sidelines. Call it Trackball.
