[01]What Are the Start Commands?

The start commands, explained

On your marks

On this command you settle into the blocks, hands behind the line, feet on the pedals, and find a still, balanced set position. Take your time, there is no rush until the next command.

Set

On set, you lift your hips above your shoulders, load your weight forward over your hands, and hold completely still. Any movement now is a false start. The gun can come at any moment after everyone is set.

The gun

The gun, or a horn, is the signal to go. You drive out of the blocks and into the drive phase. Reacting in under about 0.100 seconds is ruled a false start, so the goal is a fast reaction, not a guess.

On your marks, where you settle into the blocks; set, where you lift your hips and hold still; and the gun, when you react and drive out.
What do you do on set?
Lift your hips above your shoulders, load your weight forward over your hands, and hold completely still until the gun. Any movement is a false start.

Not faster than about 0.100 seconds. A block push quicker than that is ruled a false start, so the goal is a fast reaction, not anticipation.
