Cramp

On my last two runs I have have severe cramp in my right foot and calf, starting from about 2 km into the run, and lasting until the end. It was quite difficult to make it through to the end, and I am worried that if it keeps happening, I will not be able to progress as far as my 10km target.

I have a few theories as to why this is happening. (1) I am not hydrated enough. I think I read somewhere that this can cause cramp. (2) This is the beginnings of plantar fasciitis, the scourge of runners everywhere. (3) My shoes are too tight, or don't fit properly, or something.

I seriously hope it is not (2) as this can take some time to heal. So for tonight's run I am banking on it being one of the other two. I am going to make sure I take on enough water beforehand and will try and runn with slightly looser shoes, and see if it makes any difference.
