Whenever I run or cycle I get major cramps in my calf muscles which prevent me from running as far as I want.

I can only run for 5 minutes before the cramps begin. It is very frustrating.

I warm up heaps with stretching and walking yet I still get them. I am also reasonably fit.

Is there any supplement you can take to counteract cramps or sore muscles?

I have some magnesium so I took 1 today, will that help at all?

Maybe its a diet issue. What causes cramps apart from inadequate warming up?
