I'm thinking about 500 with hr and cadence, and thought cadence would have been more use to be than hr.
Care to explain how hr had helped you more?
The following is probably a bunch of nonsense in relation to how actual physiology works, but it's just from my own experience.
I'm overweight, and despite riding as much as I can, I've simply not been able to shift the weight. I already have a reasonably good circular pedal stroke on the flat (I think!) from about 10 years of semi-regular cycling (some much more regular than others) but due to the extra weight, I struggle badly on climbs.
I have a double chainring so my cadence is generally as low as my bottom gear will let me go on any big climbs, so it's not that useful data to me, as far as I can see.
I used to ride as fast as I felt comfortable, but at the start of the year I found that I was suddenly getting burning muscles (without getting particuarly out of breath) on climbs, which would cause me to slow down considerably afterwards. I also started getting cramps in my legs as well.
Since I got the HR monitor I can now see exactly where my effort level is in relation to my lactic threshold, and instead of relying on my body's feedback system (which was apparently not working earlier in the year when I was getting lactic burn without prior warning), I can now see when I'm beginning to overdo it and ease up (except on the bigger climbs where easing up isn't an option).
Being able to choose and pick when to ride high intensity (usually on the flat
) means that I can save myself for bigger climbs, basically.
