Air. They just blow them up before the races and release the air after the races. Jon13
Normally, they are called pylons or "air gates".
If you leave your home for a walk, or a trip or a race-we'll use that. you start your race on the track where the pylons are, you run 800 meters around the circular track. which brings you back to the pylons for the end of the race at the final meter. SO BASICALLY- the starting line doubles as the finish. you start running at the pylons, and end the race at the pylons also. and it doesn't HAVE to be a circle, if you start a trip from your home, walk to the store and come back home. you start at your home and come to the end of the trip at your home also.
