My friend was busting my balls to day that this is primarily a woman's condition, which may be true. The physical therapist I'll be seeing has treated a bunch of male cyclists with this syndrome over the past few years. Strikes me as the long distance cyclist equivalent of shin splints.

I think women are more prone to it due to anatomy and childbirth, etc., but I would imagine that combining 90K road cycling miles and middle age will do it to you too.
