Has anyone had foot cramp after running? or any other cramp; I suppose the cause is the same? I have been running for a while now and for the first time had a cramp in my foot about 20 minutes after getting back from a run yesterday (7k run followed by 4k bike ride home). I had water before and tea after, so I am not sure it was dehydration that caused it, although of course it is a bit warmer now. anyway, very glad the good weather is upon us and I can now run in the light in the early mornings!
