Bruce,
As to your question about your MHR, someone here can probably come up with the estimate method for that metric, I understand that you can do a fairly good estimate with a TT type ride, of a given distance, not sure of the details about this, though. The number you gave, 114 sounds a little low, for your level of fitness, to me. The Joe Friel book, The Cyclist Training Bible, has a method for getting this without doing a stress test type MRH measurement, also, (great reference book, if you don't already have a copy, I use mine frequently for my education.)

Please keep us updated on how this goes for you, and what happens in the sessions. I am interested in learning about this.

Bill
