I have not been one to get cramps, but lately it seems that they are increasing in frequency and intensity.  
 
 
In the pool I kept getting little cramps in the arch of my foot, these are painful and irratating, but two days ago I got one so bad in the calf, that I had to stop swimming.  (These may be related to pushing off on the turns as the turns seem to bring them back.) 
 
 
 
Today, I did a long, hilly bike ride (65+ miles), followed by a run.  Everything seemed to be ok, then I hit a downhill on the run.  I tried to extend my stride and WHAM!  The hammy locked.  I immediately stopped and stretched.  Tried to take a step and WHAM again,  All the way from behind the knee and up to the Glute (sp?). 
 
 
 
What's happenin?  I believe my hydration is good  (I weighed the same before and after the brick), and I had 1/2 a banana for potassium.  Any of you have ways to prevent these? tricks?  foods?  Vitamins?  ANYTHING?
