whenever I hear cramps, I think of
- sodium
- calcium
- magnesium
- potassium
I don't normally cramp for average rides. but when I plan all day rides, I take those 4 supplements, the nite before, the morning of & at the 1/2 point. then when done, soak in a warm epsom bath w/ a little red wine & massage those legs
- I use pills from the drug store
- the magnesium is a very low dose
- for the sodium, I just sprinkle table salt in my water, not enough to taste, but I also also add a squeeze of lemon juice so that might mask it pretty well
you sound like a more experienced rider than me, so please excuse my sharing, what you might already know
