Like the 400m, the characters have stamina that will run out if they run too fast. If it depletes, the player will stop running for a short time as the meter refills. If it runs out when a racer is about to jump over a hurdle, if the player's timing is poor, the hurdle is not cleared. The sprint at the last hundred meters is also present. Like the 110m, if a hurdle is cleared with perfect timing, characters receive a speed boost. If they hit a hurdle, they stumble and lose their current speed.
