Bike is very comfortable, I've worked on that for hours. But feeling as if they're going to cramp, right on the edge is way it feels. I get off the bike & stretch or walk a few minutes & it's gone for a few miles. I bought some bananas today to try that. I stay very hydrated & eat carbs at the stops but, not much Gatorade. Where can I get electrolytes to add to water ? Or will the Gatorade powder work.
