Both teams line up behind the line and each has their own sprint track.
The focus here is on responding to commands while sprinting, Goal of the players is to be first through a gate.
This can be the gate at the end of the sprint track. However, a command can also be given by the trainer to run through a gate at the side of the track (pots/cones).
Sprinting forward, backward or really stopping and turning around are all possibilities.
Fun of this game is that you can turn it into a little competition. As a trainer, you can give the commands in such a way that the score is always exciting, because not always the fastest sprinter wins, but the player who reacts the fastest.
