I'm a pretty salty sweater as well. I haven't experienced any adverse effects from this. Last night I rode an 'easy' 45 miles and felt great. At the end of the ride I literally had chunks of salt dried in my hair. For the guy who said, "You'll get there." I'm pretty fit, been putting in over 500 miles last few months and I'm still a salt lick at the end of my rides, so if I'm not there yet, I guess I never will be. I think some people are just salty sweaters. I will say though, any of my rides over 60 miles I come home and crave salty foods. In general, I prefer salty over sweet so I dunno if this has anything to do with my saltiness.
