I usually ride my workouts indoors and outdoors at 80-100 rpm but I found when climbing outdoors my cadence usually is nearer 65-75 rpm when climbing a 10% slope, for example. That cadence is out of the saddle (my strenghtness), on the saddle cadence is a bit higher.
Since my gran fondo events are pure climbing, I’m thinking of improving strenght doing low cadence interval training outdoors.
Which % FTP should I target when doing these intervals?
One of these workouts per week would be enough?
I assume rule of thumb of ~6% slope steady climb to perform the workout at 50-60 rpm. Correct?
Interval resting should be at Z1 with high cadence to recycle lactate or should I target only a little less power so my body learns to work witch acid?
