Your acceleration isn’t bad. One thing you should think as you transition to upright running is keeping hips high. This will help maintain front side mechanics and posture. Remember not to press the whole 100m or you will breakdown and tie up at the end of the race like you currently are.
thanks for watching and the feedback.
You are also hitting the nail on the head.
Acceleration over the first 20-30m is usually ok.
But then there are two issues
1) My maximum velocity is reached already very early (after 30m) and is then in absolute not high enough
2) I get too tight in the end and slow down too much.
In the below picture (as link, you need to copy&paste; in browser) I charted the actual and estimated velocities (yes, you are right, I love data and graphs..)
The blue line is my best 100m run at 12.47 compared to the top 5 masters sprinter in the 2003 world masters championships based on a thesis of a finish professor.
Do you have some drills to recommend to get the transition better and hold the hips high?
Will this help to reach higher top speed and /or avoid getting to tight and slow in the end?
