Couple times in the past week I started cramping in the calves during my ride (first time this year; rides are typically 20-30 miles). Read up on it, most answers are "hydrate!" and "eat bananas!" (potassium).
I often eat a banana before a ride but don't detect a correlation with cramping... so thought I'd check out potassium supplements. The ones I looked at supply 90mg K, or just 3% DV. Eat one banana and you get 8 times that much. So this doesn't make sense to me - I expected a "supplement" would deliver ~100% RDA, or at least significantly more than one would get from a normal diet. Can anyone comment on that?
Also - any other recommendations on cramp prevention (topic is beaten to death, but I'm asking anyway).
