Again you shows two things :
a) You don't understand anything about training. Mo Farah, and Eliud Kipchoge (who in any case I don't think can run his PB of 5000m at the moment) WERE ABLE TO RUN FAST SHORT DISTANCES WHILE PREPARING LONG EVENTS.
The case of Kejelcha is the opposite : he was able to run fast a HM preparing something shorter.
When we increase the volume raising the LT (using fast long run between 10 and 20 km, and long tests on track at a speed a little faster than the LT, or tests of middle length at the speed of LT, with short recovery and big volume, or finally long distances with variations of speed, with the recovery at a pace of 80% of the 10000m speed), WITH FEW WORKOUTS OF SPECIFIC SPEED ENDURANCE for a shorter distance we can improve our PB.
The opposite is not possible.
So, if you are an athlete of 800 and 1500m, when you start to increase the volume looking at 3000m, automatically you improve in 1500m.
So, the rule is : when you prepare the longer distance (10000m looking at 5000m, 5000m looking at 1500m, HM looking at 10000m, Marathon looking at HM) you can improve your PB in the shorter, maintaining workouts of speed endurance in bigger volume. When you mainly look at speed, not only you don't improve your PB, but step by step your performance becomes worse.
b) You are a total liar, putting in my mouth something I NEVER SAID : for example, that I say the merit of the explosion of Mo Farah is mine, when simply I explained what Mo did, and how I adviced him, during the period between October 2009 and August 2010, immediately before going to Alberto. You can read what himself wrote about that period in his biography.
I never said I have the "magician potion" for making miracles with the athletes. On the contrary, I respect a lot of coaches (during the European Championships I was in the Team of Norway and I could know very well the professionalism and the system of Father Ingebrigtsen), because we meet frequently, speak together as part of the same world. So, we know each other, and know their training principles, their mentality and their ethic values. For that reason, there is some coach we don't trust too much, because lacks the last point (but, please, don't ask me the name...).
It seems you are doing a crusade against myself, because I'm able to produce top results without doping, and this can create doubts about your "faith" in the big advantages of blood doping.
Sorry if I continue to produce top results in clean way, and like me other coaches working with Kenyan and Ethiopian runners. Our final goal is to drive the athletes to run fast on the track and on the roads in clean way, not to win the competition of the higher Hct.
