I am new to cycling, but not new to athletic activity in general. I did not think that cycling would have such a unique effect on me, so I am a little confused:
When I go for longish rides on my roadbike, I get "the shakes" pretty badly unless I frequently stop and eat something. Is this normal? Why does it happen?.. I eat a well-balanced diet and avoid simple carbs, so it seems to me that this really shouldn't be happening. It has never happened to me while performing other forms of athletic activity, including XC skiing and hiking, which I thought were equally strenuous. Does cycling have some sort of special effect on glucose processing, or am I doing something wrong?
