Catrin - I too am hypoglycemic and I find that I have to use more than Accelerade for my electrolytes. Accelerade works great for sustaining my energy levels but I have to use shot blocks with it or gatorade (full strength). It's been so hot here lately I'd say you are losing more electrolytes than you think. I have been sweating so bad that I'm salting out. My face will get tiny salt crystals on it and it looks like white dust. If I dump water over my head I can taste salt water running over my lips. As long as you are eating enough before going out on these longer rides I would guess you are experiencing cramps from lack of electrolytes. Add shot blocks and try that.
