This article from the Well blog at the New York Times is about a month old, but I don't think I've seen it mentioned here (please forgive me if it has). It reports on evidence gathered by (in part) a researcher at University of Oklahoma that shows lower-than-average bone density in competitive cyclists. Why is not clear-- it could be leaching of calcium by excessive sweating, or it could be to do with the lack of skeletal stress during extreme exercise. Drinking calcium-enriched water while cycling was determined to be helpful. Neither runners-- who certainly do have skeletal stress-- nor weight-lifters-- who have much less-- were measured to exhibit the effect.
