No I got second, but it was a .25 improvement over last year and my best time since coming back 3 years ago after 10 years of not training or sprinting. 3 years ago I ran 12.45, this year I ran 11.44 and last year prior to using the Cheetah Sprint Start, I ran 11.69.

I have a college female athlete that ran improved by .4 after one week of training with me. She was running 12.34 and 25.60 prior and after learning this start she ran 11.90 in the 100m and 24.34 in the 200
