As the run continues, you've got to be in a rhythm. Nice, high knees. Upright torso. Balanced and relaxed. A consistent run is the foundation for a consistent plant and takeoff, and the plant is coming up fast.
In my own case, I've been trying to change my plant for the last couple years, so I'm a bit more lucid during this section of the vault than I consider to be normal. Even so, like a dream, my memory of this section of the vault disappears by the time I land on the mat -- if I have a problem here, it can take me a few attempts to notice, let alone to correct.
