"there is a critical period where it is optimal to really lay down the big load blocks and there is a quantifiable difference to be had by placing a training camp 4 mths vs 4 weeks before your goal event"
"The period of
time between 3 and 12 weeks prior to the event is the critical period in which load has the greatest effect on performance for most athletes. That loading block from weeks 7-3 is particularly important for most athletes and a big relative performance jump can be exploited with significant loading in this block (a training camp, a couple of big weekends etc)"
"The period of time from
weeks 12-26 before the target event can best be termed
training to train.
It is a period that, in terms of undertaking heavy training loads, risk greatly exceeds reward. To put in perspective, a 6hr solid ride in this period is worth less than what a moderate 3hr ride would be worth during the critical loading period! Yet undertaking these loads in the early season could significantly compromise the athletes ability to undertake the big loads when they count. This is a very common occurrence among self coached athletes, the so called February Rock Stars.
By far, the most important training for all athletes occurs in that 3-12 week window before their key event. Any training before this, while not insignificant is merely setting the scene for the real training to come
Ora anche se è bello vedere che a Febbraio fai dei miglioramenti mirabolanti e tutti sono felici

bisogna tenere molto in considerazione ciò di cui sopra. Conosco più di qualcuno che a Febbraio è stato fatto andare a mille e a Giugno aveva nausea della bicicletta.
