Tonight i ran a little over 15 miles in 1:40. I finished the run about 10PM and it was still about 88 degrees and 75% humidity at this time, so real sweat producing weather.
I sweat alot when I run, and I weighed myself both before and after the run and I went from 146 to 138. I dont take in any fluids on the run, so thats just about a gallon of sweat total and comes out to about a cup of sweat per mile.
Anyone else weigh themselves like this to see how much they are sweating during their runs?
