Relentless Ambition

Well, i’m still not sure about leaving my coach. By reading and doing lots of research on this forum I’ve seen that ‘beginners’ need a longer GPP and basic fitness before speed work can be done. Alot of information to be found here: http://www.charliefrancis.com/community/showthread.php?19789-Speed-endurance-the-key-to-all-11-12second-sprinters

We had a discussion yesterday and he told me I’m far from my potential, and that with all my injuries and such it’s normal that speed work/power work was very limited. I duno I don’t really feel like leaving him, I have to think it through.
About the lactic work, I told him that when I ran 22.38 last week, my last 50m were horrible. He said I lack '250+150 workouts with 90 sec rest after the 250. I remember you, T-Slow saying the workout itself can’t really improve a 100m time, could they improve my last portion of the 200?
