I am one of the pickle juice faithful.

Don’t drink/eat pickles (dill) prior to or during, but frequently I will have a swig after a long hot ride in high temps especially when I cramp in the evening or worse yet, in bed. If I cramp in the evening pickle juice + a magnesium tablet always takes care of them.

I did start to cramp last summer on a 12% 1/2 mile climb after 70 miles. Wished I had a pickle then.
