When I do a work out I will do 3 types of sets.
The first is I hit the Power target at a cadence that is natural for me, usually 75-85.
The next block ,I again hit the power target but now I start shifting into higher (harder) gears until my cadence is < 55-60. If I pedal any faster, I will go over the power target.
The next block, I again spin up to the power target but now I shift to progressively easy gears.
This makes me pedal faster until I get to about 95.
I just keep varying between the 3.
I do this on endurance rides and foundation days.
On Tempo or VO2 days, (the hardest work outs), it takes all I got just to hit the power target at what ever cadence it takes.
I typically race 1 day, foundation X 2 days and Tempo X 1 day per week.
I rest 3 days (M-W-F) because of work issues but since I take days off, I can push a little harder. Plus, I’m old so extra recovery in not a bad idea.
