Peter, I don't use any micro or macro or meso cycle with middle distance runners.
In the history of methodology, periodization (or better, CLASSIC periodization) was something coming from scientists specialists of the strength and of the nervous system. The first studies were done by Zachorskiy, followed by Verchosanskiy, all from Soviet Union. The first top application ofd these methodology was with throwers. The best coach applying this system was Bondarchuk, former WRH of hammer, that became the coach of Yuriy Syedikh (still WRH), Juri Tamm, Sergeiy Litvinov and Igor Nikulin. They used to come for 2 months of training in Italy, Tirrenia, and I've the opportunity to have a lot of talk with them.
Following this system, coaches for middle and long distances in Soviet Union were able to complicate all the idea of training, losing completely the road of practic application of the principles.
In 1990, I was responsible of Italian Team, we went to European Championships in Split, winning the following medal : silver in 800 (Viali), silver in 1500 (Di Napoli), gold in 5000 and 10000 (Antibo), bronze in 10000 (Mei), gold in steeple (Panetta), bronze in steeple (Lambruschini) plus the 4th place of Carosi, gold in Marathon (Bordin) and silver (Poli) plus 4th place of Bettiol, bronze in 3000m W (Brunet), 4th in Marathon W (Scaunich), National Record in 10000m W (Dandolo, 5th).
During a session on the road with the athletes of long distance, while following with a car, I saw something strange in another car following me. There was a man, out of the window, with a videocamera, recording..... 25 km of long run at 3'40" - 3'30", even pace !
The next day I saw again this man, hidden behind a tree, recording everything about our warm-up. So, I went to him, asking who was and what he was doing. He, with a very bad English, explained me he was a Soviet coach, wanted to learn from the best European Country. I told him that, because we learnt many things from Vladimir Kuts, Pyotr Bolotnikov, and, in 1978, Antipov and Fyedotkin, probably it was better if they could continue their old experiences, instead moving for a new "Periodization" with macro-meso-micro, completely wrong for our type of events.
The situation of training is very simple :
a) You have to build up your aerobic base, and this process can last about 10 years, growing at the same time both in extension and in intensity
b) You have to build up your body, and this process can last again 10 years, using correct weight in order to increase the strength you can specifically use in your event
c) You have to improve in your ability (coordination), in order to reduce the cost of running at the same speed
d) You have to build your mind, thru the increment of volume and intensity, making easy what, before, was difficult.
In this situation, the most important points are :
1) NEVER you have to lose what you were able to conquire. This means that, if you are a 1500m runner able to run at the end of your winter season, 1 hr at 3'30" (17 km), you CANNOT reach your best results if, in July, you are able running 10 x 300 in 42" with 1:00 recovery, but in 1 hr you are only more able to run 15 km. TRAINING IS TO ADD, NOT TO REPLACE.
2) NEVER you have to stay too long time without competing, for maintaining the nervous level and the motivation at a high percentage (never under 85%). Everybody knows that it's very difficult to plan long periods of training without competitions, and in our events we, fortunately, can run different distances, according with the technical program we are using at the time. This situation is not possible in technical events (this is the main difference between throwers or jumpers and middle distance runners) where who is a javelin thrower can compete only in that event, but, during the periodization,also throwers used our same system, for example a period throwing with more light implements (Shot 6 kg, or Discus 1.75, or Javelin 600 gr) when want to improve speed, and another period with more heavy implements when want to work for strength.
3) not less important, referred particularly to professional runners, don't forget that their profession is to run, they can earn money only thru the competitions, so they can use competitions during the most part of the season, also when are not in top shape, as training. In which other events is possible to be paid for your training ? Life is something real, people has to eat, and with micr0-meso-macro without competitions you don't eat, if you are Kenyan, Ethiopian or, also American and or Australian.
Don't forget that Russian athletes were Statal professionals, they had a salary and were paid for training before competitions. And, not only, at that time, in URSS it was not possible to have a private activity.
And also don't forget that the "pariodization" and the "methodology" of Countries using doping as basic plan must be very much different from what you can do without using drugs, apart the motivation.
For top results, we need top quality, and, for training and growing in top quality, we cannot "squeeze" too much the training (for example, intervals every 2 days), because the body becomes tired, not more able to have a correct supercompensation, and no more able to produce quality. So, we need to have MORE MODULATION between speed and endurance, quality and extension, in order to create the base for exhalting the personal quality.
An example of this, can be the results of my athletes during WCh 2005 in Helsinki :
3000 st : Shaheen winner (95% of shape)
3000 st W : Dorcus Inzikuru winner (100% ofShape)
10000m : Moses Mosop bronze (with PB)
3000 st W : Jeruto Kiptum bronze (with PB)
Marathon man : Alex Malinga (UGA) 6th (PB, he had the time between entrants n. 82)
5000m W : Zakia Mrisho (TAN) 4th (PB), moving from 15'03" to 14'44"
The problem, for professional athletes, is not to be strong, but to be in shape WHEN THE TOP CHAMPIONSHIPS ARE. For doing this, you must forget every classic theory about periodization
