300m hurdler 

An incredibly dim witted male or female, who feels the urge to run their butt off while showing off by jumping at designated times within the grueling 300m hurdle race.

Do you see how much he shows Jesse shows off? He must be a 300m hurdler.

300m Hurdles 

- one of the best events in track & field. this race is a SPRINT, and involves speed, endurance, and skill. some people have a certain lane preference because of the curve in this race. It is one of the most demanding races, but feels amazing when you get a really good time.

The sprinters run the 300m Hurdles race.
