OK, this thread is similar to Dutchy's.
After a strenuous ride, my calf muscles continue to twitch. Often for several hours after the ride. They don't cramp up but continually and painlessly twitch.
I suspect it is my muscles trying to rid themselves of lactic acid. Does anyone else experience these symptoms or know how to prevent it from occuring? My family is rather fascinated by this phenomenon and my wife says that it looks disgusting, like something is crawling around under the skin!
