I have a question about cadences indoor vs. outdoor.
I have been using TrainerRoad for almost exactly a year now and absolutely love it. When I am doing their workout indoors, I usually keep my cadence in the 90-95 range for most things. I find my legs start to burn out when I drop below 85rpm and are sorer the next day. When I am riding outside I have no problems keeping my legs spinning in the 95+ area, but I live in Los Angeles, and we have some monster climbs that I love to do. The problem is when I hit the steeper grades I find myself dipping sub 85rpm and down to the 70s at times. I would like to keep my cadence higher, but I would blow up after a few minutes, and some of our climbs can take hours.
So my question is - should I be training at lower cadences when I am on the trainer or should I continue to keep the higher cadences going and hope my fitness will catch up to the point where I can keep my spin where I like it outside?
