About a month ago I started working on my cadence, trying to up my average over a ride from the low 80s to about 90. I managed to make the change over the course of a week or so to the point where I no longer had to think about pedaling faster, but the past couple of weeks I've noticed that my butt gets sore sooner than it used to. I find now that after about 2 hours the area of my sit bones is quite sore and I find it hard to sit still, having to stand up and shift positions much more frequently to relieve the discomfort.
Can the move to a higher cadence have caused this, or is it just a coincidence? Has anyone else noticed a similar effect? Do I just HTFU and wait for my body to adjust to the new cadence or is there something more to it?
