That might be part of the issue too. I increased my salt intake to counter lower blood pressure (it's normal atm) but I still always border on hyponatremia on longer runs. It's like I sweat all the salt out right away, but then continue to lose water. However, running 3-5 miles at a time, I'm probably fine to lower the salt a bit.

I like to rinse my face when it's warmer but it has to be over 70 for me to be ok with that Now I just rinse it at the end of a run.

Thanks!
