Reclast?

My line of thinking (I hesitate to say reasoning) is that a lot of calcium is lost during cycling even if you're not sweating because of the constant firing of muscle neurons. Hence cramping in the legs and nowhere else.

I know I'm drifting here...like Mimi said,most sports drinks don't have calcium yet cyclists always get leg cramps.

Well. That helped me think something through anyway

Endurolytes. I have a friend who swears by them, to the extent that she brings a big baggie on all the century rides, and hands them out to her cramping friends. After she gave me three of them at the lunch stop on KCBC, my feet stopped cramping...

All Hammer products have some calcium, but then they have Endurolytes (capsules or powder) if you need the balance to swing more toward electrolytes than calories.

That is an interesting point. I have been having pretty bad leg cramping on my last few rides, of let's say 35-40 miles, as opposed to what might happen previously on a hilly 55-65 mile ride. Somehow, I suspect many of the issues I am having are all related to my lack of absorption of calcium, and perhaps a Vitamin D and magnesium deficiency. I just can't believe that I have become "weaker" all of a sudden. I need to find a doctor or someone who can put all of this together. Well, the endo. will be first and then perhaps a nutritionist and an orthopedic doctor.
If I hadn't been tested for every disease known to mankind two years ago, I would suspect I have celiac or Crohn's, but everything came out negative.

I forgot to mention, the 50,000 i.u. of Vitamin D (Drisdol, Max D3/1.25 mg) is in one pill so it really is a huge dose all at once.
