Hi from Vancouver. Also in a new facility that opened May 1. Also M3's. None of the other instructors understand watts. I have trained outside with watts so have a good grasp. Also done a bit of reading on watts.
Get yourself a book like 'Training and Racing with a Power Meter' by Hunter Allen and Andrew Coggan, Ph.D., Velo Press.
Also, as a member of ICI/Pro, you have access to the blog/postings by Gino Nacey. He has done a lot of background work on using power.
Power is to cycling in the 2010's what heart rate monitors were to cycling in the 1980's. Hmm, heart monitors haven't caught on for indoor cycling yet...
I did a functional power threshold field test in my class tonight on the M3's. The advantage here is that participants don't have to have a heart rate monitor. They just have to remember their FPT. We will use that in the classes.
I don't worry about teaching new classes about zones. My focus is on getting them to work at a certain percentage of their threshold. I talk about the need to mix up their training, doing a variety of workouts to see improvement. I leave the zone stuff to the more diligent riders - the ones who are training.
