so... You may be perfectly healthy amenorrhaeic, but see your doctor to be sure they don't want you supplementing with some hormone to make up for the loss.

Interesting that your base training is 100 miles per week higher than your race period (so to speak).

I need to start taking calcium!! Thanks for bringing that up. I had thyroid cancer a few years ago and had a total thyroidectamy. So along with no thyroid, some of my parathyroid glands were destroyed. So that plus this added up means I really need to see a dr. and see about supplementing.

During race season I focused more on 2 hour rides, since crits here are 45 min +3 laps. Now that race season is over, I have switched to slower longer endurance rides and am not working on power like I was.
