I'm trying to understand the value of "easy days" in the middle of the peak season and what energy system I am training, if any, by doing them. I have a particular question about my training plan, but also I just don't understand what I am working on these non-rest, non-interval, non-event ride days. Note: I tried searching on this and other forums, I have a power meter and have read the Allen/Coggan book and have not found the answer or am too dim-witted to comprehend it. I am not a road racer, my objective is to be very fast at 100-200 mile hill climb rides.
In my season (May to Sept) - now - the week looks like this:
Mon - off
Tues - hill intervals (VO2max)
Wed - easy - 2 hours
Thurs - FTP intervals
Fri - active recovery (up to 90 min)
Sat - easy 2 hours
Sun - 100-200 miles, 7-10K of climbing (event) or shorter group ride of 70 miles, 6K climbing.
So in season, what is the purpose of Wed and Sat? Build endurance? But don't I already have that through the super efforts on Sunday? What level should these rides be at - 1 or 2? Do these days add any value? If the value is solely like active recovery is it reasonable to substitute other activities (like walking, etc)?
