Emily, I started riding as I was in the worst throes of perimenopause (the last 2 years). I got my first road bike around the time I had my last period. When I started riding in 2000, I weighed about 118-122 (if you can believe it), basically from being burned out on the exercise I had been doing for 20 years. I had gotten myself down to 110 a couple of times when I was heavier and in peri (basically for my kids HS graduations). I wasn't inactive, but it wasn't enough to neutralize the effects of hormones. I also changed the way I eat quite a bit in late 2003. I had been riding for 3 years, one year on a road bike, and I weighed about 107. At first, I was pretty happy with that weight, but I really wanted to get down to around 105. I've had to change up what I do in terms of exercise, every so often and modulate my grain intake even more since then. I just can't slack off. Given that I still enjoy red wine and chocolate and I go out a lot, it's OK, but now I can't stop going to those boot camp classes....
