Recently got a copy of Cutting Edge Cycling, by Hunter Allen / Stephen Cheung.
In it, they talk about a variation from the typical training week (short, interval-based rides on weekdays, longer rides on weekends) that make up a typical training cycle - viz, block training.
Here, you focus on one type of training (eg, FTP intervals) for consecutive days till exhausted, then rest/recover and repeat - for a certain number (recommendation of 3 to start with) such blocks. Then you start another set of blocks with a different goal in mind (endurance, power, etc).
The authors mention that this works for people who are not necessarily constrained by long working hours (with this training, you may have to do several days of long rides on weekdays, if you are doing an endurance block), but that results are often better than with the typical training week.
Anyone using this method? If so, how do you structure it - what is the sequence of areas you work on, how many blocks, how many days per block, etc.?
