Keeping from cramping???

[Mister Discotheque]

How do I keep from cramping up? I was on my last lap at Prospect Park on the uphill on my bike, and my calf locked up and rendered me useless. What can I do, besides stretching?

not an expert by any means... but i'm pretty sure increasing the amount of water you drink will help prevent cramping....
