I know what you're talking about Muffin Girl.
Ok, I'm actually relatively flexible, I can still reach down and put my knuckles on my toes, but never-the-less, my hamstrings (and lots of other muscles) are still feeling very tight. They cramped a couple of times over the weekend while I was doing virtually nothing.
Anna, I eat loads of bananas anyway (good source of potassium).
I'm beginning to think I've just got naturally tight muscles. It's not my imagination. I can feel the areas of tightness when I rub them.
Oh well, stop complaining Garr. At least you can still run!
