How to play
- Stand still in view. Wait for ON YOUR MARKS · SET · GO.
- Moving before GO is a false start — you are sent back to the blocks.
- Then lift your knees as fast as you can: faster knees = faster sprint. On a treadmill, just run.
- 400 m: pace yourself — sprinting flat out drains your stamina.
What you train
Wait for the gun, then sprint 100 m or 400 m on the spot. High knees set your speed — or run on your own treadmill. Move before GO and it's a false start. The 400 m adds stamina, so pace your lap.
