Its frustrating to have this one body part hold me back from riding with the faster guys. Is it my pedal stroke, my shoes, bad genes.......??? Any thoughts?
not to be contrarian here, but i've always heard that cramps are usually from lack of hydration, specifically a lack of electrolytes.
are you drinking plain water or a sports drink? not to say that plain water is bad (or gatorade good), but even plain water with a bit of salt may do the trick to keep you hydrated better.
hope that helps.. i've had cramps in the past and after some stretching, resting, and eating/drinking i was good to go.
