    Hello Henk,
    I will understand if there is no reply since my questions is perhaps too individual.. but I’ll try anyway. My son is just turned 15.. Height 1,87m, skinny/muscular, very high muscle tonus(nearly stiff,) and his 100m time is about 11.8 secs.
    He is a very “strange” athlete ( I am a 400m runner and strange for me is what I thought till now to be true , but perhaps I am wrong).
    Although he is usually the tallest , he is the fastest out of the block. He is usually ahead till the first 50 meters but then starts to get reeled in by the other athletes. I always thought that the “opposite ” happens for tall athletes i.e slow out of the blocks and then catching up later die to slower deccelaration?

    He has very very low kneelift.. and he sometimes gets injured on his hip extensors. He is also more interested in Powerlifting and does not get nervous at all in the few races that he does.
    What are the basic running drills/ excercises that I should do with him ? How can I keep him not slow down so fast after the first 50-60 meters ?

    Thanks You,
    Armin Rana Ray

    • Hello Armin,

      Sorry for my late reply, my blog and email were disconnected, so I did not see your comment. And, no question is ever too individual for me although it is easier to answer general questions 😉 A tall guy being fast from the blocks and slowing down at the end, yes, that is, like you said, different from what is the rule. But the rules are confirmed by exceptions. The problem could be physical: running technique, maintaining high-speed-form or mental: tightening up under pressure of being in front and not knowing how to maintain speed. Some tips from afar: 1. metaphoric: pushing a car in the beginning you need strength to push, when the car starts rolling faster, there is no time left to push,so relax like holding on to the car running downhill: no need to push or drive.
      2.his recurring injury slows muscle dysbalance or bad mechanics, I can’t tell much about it from here.
      3. learn to play with and to control speed 5x 100 m in this way, 20m fast (95%)-20m (90% but not slowing down, no leaning backward and foot in front or “stepping on the brake”!- just maintain speed effortless)-20m 95%-20m 90%-20m 95%. rest 4 minutes. Or the same running 150m (rest 5-6 mins) 30m-95-30m-90-30m-95-30m 90-30m 95. 95% = stepping down on the accelerator but not all the way down, 90% = keep you foot there, don’t move it and next 95% again step it down. It should be hard for the coach to see the transition at each mark as far as posture and movements are concerned. Best regards and good luck

    Hello Henk,

    I recently heard you speak at Mike Boyle’s winter seminar. It was great and I look forward to having to opportunity to hear you speak again. Your book is also a great resource for me. You had said we could email you if we had any questions, so I hope i’m not bothering you with this email, but I had a few questions.

    1) How does your speed truing differ for track athletes vs field athletes in terms of how much training time is spent on (max) speed work?

    2) For the athletes that only train 3x/week for an hour and a half per session how much time would you spend focusing on speed work, strength work and conditioning?

    3) I have been looking into the Bosco Test to help me determine the muscle fiber make up of my athletes but I am having a hard time finding a reliable source. Do you have a link to the proper way to perform the Bosco Test and calculate the results?

    4) I recently just purchased a KBox from Go Exxentric and wanted to know your thoughts on it and how you would use it with you athletes.

    Thank you for you time.

    Ryan Heickert
