Thanks for that. I hope that in the future I won’t have to use it. I did follow those somewhat with the progressions and two days ago was successful in doing 6 sets of 30m starts from a crouch. I have another speed session planned today and a session with my therapist tomorrow. Last summer I was sitting in the stands at the Canadian Track and Field Championships and looked over at the gentleman beside me and noticed from his name badge that is was Gerard Mach. We chatted briefly, mostly interpreted by his son. His son said he had edited his material recently and I gave him my info but have never heard back from him unfortunately.
