I have been riding outside (as opposed to spinning) for about 2 years. I hardly ever have a really "good" ride, unless maybe a 15 mile flat ride along the beach. It seems as though every time I ride, my legs just get weak and lately I've been getting such horrible cramps in my thighs that I have to throw my bike to the ground and walk around until they go away... I try to drink a lot of liquids, but I am diabetic so I have to be a little careful about what I put in my body. I'm just not sure why my legs get so weak - any suggestions??
