The concept and all the scientific basis for it (emphasis on intensity X recovery instead of volume X intensity) were also subject of Michael J. Ross´ “Maximum Performance For Cyclists”, much in the way of Carmichael´s but with a different approach and presentation. As you mentioned, a lot of current “in” physiologists and cycling coaches have been advocating intensity as the be-all-cure-all for time crunched cyclists (is there any other kind?)

Fact is, pros get their dose of high-intensity training (HIT) from racing, once their base period is done or even during base with some judgement. Amateurs don´t race as often or as hard, so we don´t quite get the speedy rhythm needed to improve. Even training with pros isn´t the same as racing.

So it only makes sense to focus a training program as proposed by Carmichael.

Again, thanks for the writing on the subject and also on everything I´ve been reading here. Although not exactly a grimpeur myself (I´m 1.84m and 75kg), I have deep appreciatoin for the art of climbing, a big fan of grimpeurs and Charly Gaul is my hero too!!!

Keep up the excellent work!!!
