Every so often I'll develop some "small" cramps in my upper thighs. These aren't like when your whole leg cramps up, it's more like a few localized tight areas that hurt. Usually I notice them when I'm sitting in my chair at work (it's a drafting chair, so my feet don't touch the ground), or worse, when I'm driving my car. If they get really bad I need to stand up and try to massage my leg a little, but they always seem to come back when I sit down again. Generally they don't bother me at night when I'm in bed, like the cramps I'd sometimes get after riding hard that are down in my calfs.
What's weird is that these cramps only seem to happen after I have not been bike riding for more than 5 days or a week. Once they start they can persist for several days until I go riding again. They showed up again today, and I was a little worried about going on a group ride tonight (first since last Thursday, so 5 days ago), so I hung with the slow group (not that I wouldn't have anyway). What's so weird is that my legs didn't bother me at all during the ride. I can feel them coming back a little bit right now after getting home.
I'll admit that my electrolyte levels may be a tad off from most people. I don't drink milk, and I'm not that great about taking my calcium supplements. That being said, I don't hold back on cheese and all the other calcium sources out there. I have started taking along one bottle of Gatorade lemonade (great stuff, btw) on rides, along with another bottle of water. I used to just bring water. It does help pick me up a little during rides, but I don't know how much it would impact this particular problem. I'm not really sure what else to try to do about these little cramps. Any thoughts?
