I haven't really thought too much about whether menopause has caused me any lack of power, because I didn't start riding or running - or doing any type of endurance exercise until about 3 years ago. I'm now 56, and I went through surgical menopause 20 years ago, so I don't know any different!
I think that maybe one of the reasons there's a lack of information out there on losing strength or power after menopause is because no one really expects women to be doing these kinds of endurance sports after *a certain age* or menopause anyway!
We are certainly not the *norm*.
As for hormone replacement, I, like many others were scared away from hormones when all of the hoopla about hrt came around. If you read about it these days, there really was not sufficient evidence for such a wide spread scare...the groups used where very specific and not representative of the *real* women who used hrt. At any rate, I went off Premarin, which had been working fine, went on *natural* products & progesterone cream. It was ok for a while, but I experienced severe symptoms, and could never quite get it right. I did this for two years, and finally after a long discussion with my doc, went back to a very low dose of Premarin. My symptoms went away. I say do what works.
While menopause is a very real thing, it is not a disease, and I refuse to blame it on any of my *issues*.
Congrats on getting back on your bike after cancer!
