While racing, I often get extremely dry mouth (cotton mouth). It’s not debilitating, but it is an extra factor to conquer during a race that I don’t need. In fact, I’ve always had this issue. When playing competitive sports in HS and College, I started chewing gum to stave off the cotton mouth.
BTW: I’m well hydrated before races and have plenty of fluids on the bike during the race.
Do others fight this issue? What works for you?
