I have a lot of experience with cramps. The best thing you can possibly do is to ensure you are hydrated at all times. This is the number one reason I found why I cramped. Drink up and drink a lot before, during, and after your ride. And make sure you get your share of potassium. In effect, a good source is to eat banana(s) before a long ride. Finally ensure you stretch that muscle out before, during, and after your riding. Get that blood and oxygen flowing in there. You do these 3 things, and you won't have a problem.
I'm 45 and every time i ensure I have my fluids... my cramp rate goes WAY down. Try it if you think I'm full of it.
