The LCI training actually turned out to be pretty interesting. They needed to review the basic bike handling and stuff that was covered in Road I, while at the same time trying to train us how to run the course ourselves, so there was a lot to do. We ended up going through a lot of Road I again, this time taking turns playing teacher.
It was all too much for one weekend, though. It's too bad it couldn't be spread out a little more. One thing to work on on my own: I'm terrible at hard turns; I'm too afraid to let myself lean over far enough. The instructor suggested just doing increasingly tight (or fast) loops in a parking lot to get used to the lean.
It turned out not to be a problem riding this weekend after not having ridden in the last couple years. I rode back and forth to the class (at Briarwood) every day in addition to the various in-class exercises, but I don't feel particularly sore now.
