Dear Carleton,

It seems lately that I've been having a lot of problems with muscle cramps. Mostly my calves, but once or twice its been my hamstring. I feel like I'm adequately hydrated (about one bottle of water per hour riding, more if its hotter, less if I'm going slow) and eating a lot of bananas (in case its a potassium deficiency) but I still have this problem. Anything else you suggest trying?
