So, RR, you had your LT tested in a lab...how about the rest of you?

I feel very sketchy about setting my zones. I tend to use a combination of percentages I have read about it training books, the number I see on the monitor during really hard efforts when I'm gasping for breath (which I assume to be near my max), and sort of a perception of where I am regarding HR when I do rides that leave me pretty sore after.

Have any of you in Seattle been tested, and if so, where?

Is LT the same regardless of type of exertion...such as flat TT vs. climbing?

I feel like I am always guessing about to set my HRs. This has been bugging me for awhile.
