Is that why it tastes like ****?
BTW, there was an interesting video on GCN, about how different people excrete differing amounts of salt in their sweat, and how Dan happens to be one of those who doesn't excrete as much, but when he was racing he didn't know that, so during one of the big Tours he was eating the diet the team provided which was loaded with salt, so he ended up GAINING weight over the Tour instead of losing it. All water, of course.
