Here a couple of cool videos with a nice interface to show power, HR, cadence, speed, % grade and etc. They are from local climbs.
This one is from last year's low key hill climb. It is just nasty.
Here is one from the top section of our benchmark climb which I do quite often. I cannot do a sub 20 minute climb and as I watch the power production, it is obvious why. Boy I need a lot of work. It would be really nice if I could get about 10 more heart beats at my current stroke volume.
