Interval Training

I've been re-reading Friel and looking at how he sets up a week and I think I'm being extremely aggressive in my training schedule.  I do heavy interval training during the week, where as Friel only schedules three days of intervals, usually Tuesday, Thursday, Saturday (although it can be any combination of days). 

My past schedule on 2/11 and my current schedule follows Friel a lot closer.  My 2/18 schedule has four days of intense intervals, which is too much.  Going forward, I will follow Friel more closely and do three days of intervals:  power, muscular endurance and anaerobic endurance (assuming in build period).   If I need an hour workout but interval only lasts 30-45 minutes, then I'll just cap it off with an E1 or E2 ride. 

The big interval day will always be Saturday, which is 2 to 3 hours of intense intervals (spin class).  The extreme class usually ends as the weather warms up and us bikers move to outside riding.  I will make Tuesdays more power and Thursdays more anaerobic endurance.  I'll let spin handle muscular endurance for now. I'll adjust next weeks workout to reflect this.
