Hammer works for me but High 5 Zero is really good too. And SlowMag fizzles in the back pocket can be a life-saver. Yes, people can say what they like about training time/distance intensity etc. Obviously it is going to undo you if you don't train properly, or hydrate properly, but for me cramps are not always directly related to these things. I can be doing 100km+ regularly with a fast group (well, for me!) and do fine, but then go do a short, easy ride in good weather and start cramping from the beginning. So from experience and lots of thinking about it I worked out for me sugar is a definite kicker. Coke especially but other sweet stuff as well. I don't generally eat/drink stuff with sugar in it but when I do, even without exercising, I will be prone to (or actually get) cramp, just doing nothing! Don't underestimate diet!
