Instant Relief for Leg Cramp

[kap]

I thought I was well-prepared for the long ride in the heat by drinking lots of fluid, i.e. Gatorate and juice; eating Cliff energy bars and Cliff blocks. Still, the past Saturday in the middle of a 50 mile bicycle ride I had muscle cramp in both of my inner thighs. I made it home but I was extremely tired. I had to skip an easy 15 mile ride the next day. Now what did not I do right? And what I should do better for this coming Saturday ride? TiA
