Just about a year ago, I went on a canyon ride on an empty stomach and probably dehydrated from festivities the night before. My right calf seized up on me and I learned my lesson! (Sometimes the hard way is the best way since it's more memorable...)
On two recent rides, the same calf sent messages that it was thinking of doing the same thing. I slowed the pace and was able to thwart it both times. I may not have eaten recently, but I wasn't on an empty stomach and I certainly wasn't dehydrated - just pushing myself relatively hard towards the end of my rides when I felt it coming on.
What's the skinny?! How can I avoid this? What am I doing wrong? What's your expert advice?!
