Max Velocity drill

Flying 20

Develop and hold genuine top-end speed, which is where line breaks are finished.

Setup

Three cones on flat grass: cone A at 0m, cone B at 20m, cone C at 40m.

From cone A, build your speed up smoothly across the 20m to cone B - do not explode off the line, roll into it so you arrive at cone B already at nearly top speed.
From cone B to cone C, hold maximum speed while staying tall, relaxed and rhythmic; you are not trying to accelerate here, you are trying to hold.
Run 5-10m past cone C before easing off, and never slow down inside the zone.
Walk all the way back and rest 4-6 minutes, then repeat - 4 reps total.

Treating the build-up as a sprint so you're already fading entering the fast zone
Tensing up and 'trying harder', which actually makes you slower
