Drewza, perfect explanation! This is the theory I am currently going with as well. I have been doing some research on McArdle disease and Tarui's disease which seem to align with the symptoms described by everyone.
I like your prevention and treatment especially. I will do 3-4 rides/day when I have a flare that may last only 20-30 minutes before I cramp initially, but like you said over the course of a few days the rides will gradually get longer and the intensity will increase as the excess glycogen burns off and levels normalize.
So, you have been able to relegate the symptoms entirely with carbohydrate modification during your rest days? If so, do we all just change our diets to low carb/high fat and see what happens? There have been some recent studies done on the ketogenic diet that seem promising.
I am going to see a nephrologist this Wednesday and will be requesting a muscle biopsy (to see the level of glycogen in them) as well as a genetic test to see if I have any mutations that would signify CPT II deficiency, McArdle disease, or Tarui's disease. I will let everyone know when I get the results back.
